2 02 PUMPS IN ACTION The Vacuum Journal Vacuum Trucks Samson Pumps has been delivering pumps for industrial applications for decades, and the lifetime of the liquid ring pumps is impressive. Brian Larsen, Midtjysk Kloakservice ApS Liquid Ring Pumps Expect a Long Lifetime This liquid ring pump, which has been used in the fishing industry for pumping fish between tanks, has been running since Pumps in action years lifetime with daily operation is not unusual for a Samson liquid ring pump. Some Vacuum Trucks will be equipped with a Samson pump and will go from fleet owner to fleet owner throughout the years without replacement. We have seen pumps on Vacuum Trucks that run for more than 18,000 hours without any repairs or significant servicing. This gives us confidence in our technology and a good feeling every time we ship a new pump to our customers, states CTO Kelvin S. Jensen. However, if a pump should break down and a replacement pump is needed, Samson Pumps will be ready to deliver a replacement pump without a long lead-time. Short delivery time is simply one of the cornerstones in our company DNA. We strive every day to outperform our competitors on delivery time and quality. We have learned that these elements are key to Vacuum Truck builders and fleet owners, CTO Kelvin S. Jensen continues.

3 Vacuum Trucks The Vacuum Journal Certification 03 Samson pumps ATEX Zone 0 approved for use in potentially explosive areas, Upon request from several of our customers, we ve decided to have the four model series become Zone 0- approved The ATEX directive is describing what equipment is allowed in an environment with an explosive atmosphere. Certification From now on, the Samson Pumps model series KE, KL, KM and KS will be able to be used in areas where there is a risk of explosion. The four model series are now being certified in accordance with the ATEX Product Directive and are thus eligible for use in potentially explosive areas, throughout the EU. Upon request from several of our customers, we ve decided to have the four model series become Zone 0-approved. This means the pumps may be used in areas where there is the highest potential risk of explosion and where the most stringent requirements for pumps are also in place. With Zone 0 approval, the pumps are also approved for use in Zone 1 and Zone 2, where the risk of explosion is relatively lower than in Zone 0, explains Samson Pumps project and quality manager Jan Steiniche Christiansen, who is in charge of the company s ATEX Zone 0 project. Jan Steiniche Christiansen, project and quality manager at Samson Pumps. New sales potential Jan is convinced that the ATEX certification will lead to new sales opportunities for the company s products. The quality of Samson s pumps is well known. With the ATEX certification, the pumps can now be used in Zone 0 areas and are the obvious choice for manufacturers that offer vehicles for use in many of the places with a potentially explosive atmosphere. This applies, for example, to gas stations, fuel plants, refineries, biogas plants, airports, sewage treatment plants, etc. The ATEX certification will undoubtedly also be noticed among our many satisfied end customers. If they re in doubt as to whether they re operating in any of the risk zones, they can confidently use Samson pumps because the Zone 0 approval covers all zones, says Jan. Comprehensive process TÜV Nord is the certification agency that is issuing the ATEX certification for the Samson pumps. The certification process is a demanding one, and it also encompasses the ISO 9001 certification of the company. The Samson pumps, as well as All EX pumps are thoroughly assessed before leaving the factory. their production and use, have been tested and studied down to the last detail. The entire process is documented through a large number of manuals, certificates, declarations, data sheets, compliance sheets, risk assessments, calculations and test results that are now assembled in a single technical dossier. Manuals for vehicle manufacturers and end users Among the contents of the manuals are detailed descriptions and illustrations of how vehicle manufacturers must incorporate the Samson pumps into their products, and of how the end users are to use and maintain the pumps when out on the job in a potentially explosive area. This is thoroughly descriptive material that will be very useful and applicable. It s perfect for both the vehicle manufacturers we supply and for the many end customers who use Samson pumps in their daily work, Jan notes.

The solution can be placed on the chassis and be up and running a few hours later. Truck builder! Here s your turnkey vacuum solution No more worries about how to build in liquid separators, water tanks, or cooling and temperature controls for new Vacuum Trucks VacPac is the answer! VacPac is shipped as a tested and ready to install, turnkey solution to any Truck Builder in the world. In Focus VacPac Manufacturing a Vacuum Truck traditionally involves a substantial amount of engineering hours to ensure that the truck is equipped with a highly efficient Vacuum system that fits the slim body of a truck chassis. This masterpiece of art is what makes building a Vacuum Truck unique, and Samson Pumps expertise is behind the evolution of a waste equipment market that is growing every year. However, Samson Pumps has seen an increased demand for know-how and practical experience with liquid ring pumps especially in the USA where vane pumps or blowers traditionally have dominated the Vacuum Truck market. Less noise and pollution is the new black The working environment for truck operators and government legislation to reduce factors like noise and pollution is affecting demands on truck owners. Liquid ring pumps are becoming a natural first choice for Vaccum Truck Fleet owners who are trying to adapt to a changing business. Samson Pumps has delivered liquid ring pumps for European, high-end Vacuum Truck builders for decades, and through a partnership with the Northville, Michigan-based Jack Doheny Companies, the ideal turnkey vacuum solution was born. The new, complete solutions, which include vacuum pumps, liquid separators, water tanks, cooling and temperature control systems, are delivered as a complete vacuum unit ready to be placed on the truck chassis in no time. Turnkey solutions that will reduce build time and service time New customers who are in the process of integrating liquid ring pumps into their first trucks will be able to build a liquid ring pump truck in no time. VacPac is a gamechanger when it comes to outfitting Vacuum Trucks with various pump, New customers who are in the process of integrating liquid ring pumps into their first trucks will be able to build a liquid ring pump truck in no time systems. VacPac is a complete plug-and-play solution that has been developed based on decades of vacuum know-how. The solution can be placed on the chassis and be running a few hours later. That s a game-changer for anybody who lacks proper knowledge about liquid ring pumps, says CTO Kelvin Storm Jensen from Samson Pumps. Based on our many years in the Vacuum Truck business we see that the biggest disadvantage with liquid ring pumps relates to the installation process, which is more important and complicated than that of other vacuum pumps, Kelvin explains. Liquid ring pumps normally do not need frequent service intervals, but in case there is a need to service the VacPac system, it will take less time than with a normal vacuum system. Since VacPac can be lifted off the truck as fast as it was installed, the downtime during truck maintenance will be very short.

6 06 interview The Vacuum Journal Vacuum Trucks There aren t many jobs a KM2700 can t complete Mantank was formed 20 years ago and has grown steadily every year since Mantank Interview with Nigel Barnes Senior fleet engineer, Mantank Nigel Barnes is senior fleet engineer and joined the company 17 years ago. In that time the fleet has grown from two vehicles purchased secondhand to a modern fleet of 43 vehicles. There are some eight tanks with liquid ring pumps mostly Samson. Previously Mantank used both Kaiser and Dietmar Kaiser, Hibbon and hick Hargreaves liquid rings however when Vallely tankers switched over to Samson some four years ago all recent acquisitions have been fitted with Samsom KM2700. How do they compare with the Kaisers? The 2700 although its heavier it out performs the Kaiser on suction and continuous working. Mantank Liquid tankers can be working for 2/3 weeks 24 hours per day seven days per week especially on digester cleaning where the Plant is on a three week shutdown and time is of the essence. Each shift is twelve hours and nonstop working to ensure the job is completed within the time allocated., We get top performance from The KM2700 better that anything else we have tried the operators love them and our customers insist we send the vehicles with the Samson liquid rings fitted Nigel is a big fan of Samson Liquid rings with performance and reliability top of his list for his admiration. We get top performance from The KM2700 better that anything else we have tried the operators love them and our customers insist we send the team and the vehicles with the Samson liquid rings fitted To date our best performance tanker by far is a 13 year 8x4 (12000 ltr) Volvo vacuum tanker that was originally fitted with a Hibbon liquid ring which Mantank replaced approximately four years ago for the KM2700. Nigel says there aren t many jobs that this machine can t complete. In operation everyday Mantanks vehicles are in operation everyday all over the UK operating from two depots and it s fair to say the work that these vehicles carry out are some of the toughest assignments only a few industrial cleaning companies could undertake. We can only do these jobs because we have the skilled and dedicated personnel together with the best equipment available says Nigel. Not all jobs undertaken are three weeks on site a typical job is one which we are currently engaged to collect heavy oil residue in a storage tank. The driver and crew leave the Manchester depot at six am travel two hours to Lincolnshire set up the equipment and pump the load on for approx six hours (continuous). 24 hour maintenance facility check Once loaded it s a two hour drive back to Manchester to unload at the treatment plant and back to the depot a twelve hour shift completed. Nigel and his team who, However when it comes to pumping heavy sludge s Its Liquid rings all the way operate a 24 hour maintenance facility check over the vehicle replenish all fluids and lubricants ready for the crew the next day s six am start. Nigel enjoys his role as senior plant engineer especially as he specifies the equipment best suited to the Mantank operation. He likes to keep up with new technology and carefully assesses each new development and ideas presented to him to see if they can add value or increase efficiency within the mantank operations. However when it comes to pumping heavy sludge s Its liquid rings all the way. Nigel has tried various and well engineered alternative pumping systems but nothing has come close to replacing his liquid ring pumps You just can t beat them says Nigel. After 17 years in this job we here at Mantank have the confidence to tackle any Heavy sludge up lift thanks to the power of suction and the quiet reliability of our favored Liquid rings. Nigel is married to Julie and they have two sons Steven 22 year old and 16 year old Jack who is due to start an apprenticeship in the truck/tanker business. In his spare time Nigel likes to spend time with the family and switch off from work, although sometimes it s hard when you re out and about seeing what the competitors are running. His hobbies include game and clay shooting throughout the year, training of his Labrador gun dogs, walking and skiing at least twice a year.

7 Vacuum Trucks The Vacuum Journal HISTORY 07 Who the heck is Samson? Down memory lane In 1944, the village of Tange near Viborg became home to a new type of company: Tange Specialværksted. This special workshop specialized in the repair of horseshoes and reaper-binders and listened exactly to what their customers were asking for. In other words, developments in the agricultural world influenced the development of the workshop and vice versa. Before long, the workshop was servicing most of the surrounding area, repairing everything from bridles to sewer cleaners, the latter of which gave rise to the first liquid ring vacuum pumps. Demand for this new type of pump grew quickly as new applications were found. In 1950 the company was renamed Maskinfabrikken Samson. Soon, development of the first vacuum tankers were to prove that Fabrikken Samson was here to stay. To keep up with increasing mechanization, the factory expanded significantly during the following years. In 1965, we established our first vacuum division. Since that point, we have focused on producing the world s best vacuum pump. Across a range of industries Today, we help customers in a range of industries, such as offshore, fishing, food, process and waste management. As the only company to focus solely on the production of liquid ring vacuum pumps, we have a wealth of expertise and know-how at our disposal. We therefore don t compete on price. Instead, we set the bar for quality and reliability that saves money in the long term and gives peace of mind throughout the life of the pump., We don t compete on price. Instead, we set the bar for quality and reliability Constant development Every one of our pumps undergoes constant development. Time and again our products are acclaimed both at home and abroad for their performance and reliability. Ambition, investment and potential are just part of the reason for our success. None of what we have achieved would have been possible without the right mix of talented employees. We know our customers and we know their challenges.

Samson s products are the picture of reliability, so I couldn t even imagine buying another brand of pump Pumps in action This Samson pump has given us great and reliable service for many, many years, says Brian Larsen with a smile as he gives the pump an affectionate pat. The pump is from 2001 and runs effortlessly day in and day out. Not once has the pump had to be removed from the vacuum tanker for repairs or the like., In our world, there s nothing that lasts forever, but Samson s liquid ring pumps are well on their way For our work, Samson s liquid ring pumps are the natural choice. Samson s products are the picture of reliability, so I couldn t even imagine buying another brand of pump, says Brian, who owns Midtjysk Kloakservice ApS, a Danish sewage service company in the town of Brunshaab. Samson pumps extreme reliability In our world, there s nothing that lasts forever, but Samson s liquid ring pumps are well on their way. They are extremely reliable and practically maintenance-free. Beyond the regular dose of water they require, we give them a squeeze of grease once a week and nothing more. With just that, they run day after day. We ve also had some rotary vane pumps, but they re no match for the liquid ring pumps, Brian says. Reliability means everything in a company like ours. If a pump breaks down, the vacuum tanker has to stop, and that costs us between $700 and $900 a day, in addition to the income we lose out on. Luckily, we haven t had these problems even once with a Samson pump, though we did with a rotary vane pump that we had on one of our vehicles a few years ago. We ve learned from our mistakes. Since then we ve exclusively used Samson pumps whenever we purchase new vacuum tanker trucks. We ve purchased a couple of used trucks that were fitted with rotary vane pumps. We left those pumps in the trucks until they wore out, after which we replaced them with Samson liquid ring pumps, Brian recounts. Midtjysk Kloakservice ApS has been in business for 45 years, and Brian Larsen has been with the company for 25 years. He was an employee for his first five years, and he has owned and managed the company for the last 20 years. In addition to desludging operations with its eight vacuum tanker trucks, the company also offers everything from graffiti-removal and granulatevacuum services to mobile toilet, Reliability means everything in a company like ours. If a pump breaks down, the vacuum tanker has to stop, and that costs us between $700 and $900 a day in addition to the income we lose out on and bathroom rentals. Its customers consist of private households, companies and public institutions, primarily in Denmark s Viborg region and surrounding municipalities.

Midtjysk Kloakservice ApS recently accepted one such job, which consisted of emptying sand and other debris from a drainage pipe near a highway construction project in the East Jutland region. We had to get 17 meters below ground to clean out the drainage pipe. Naturally, it was a bit of a challenge, both for the operator and the The pump has now been running for 18,000 hours without need for repairs. pump. Apart from the fact that it took a little more time than it does when we work at lesser depths, the whole process went just as it should have. Here, too, the Samson liquid ring pump passed with flying colors, says a satisfied Brian., We very rarely turn down a job if we have the expertise and necessary technical equipment to get the job done right Brian Larsen, Midtjysk Kloakservice ApS Eco-friendly solutions from Grundfos In addition to the high reliability of Samson pumps, Brian appreciates the fact that they are environmentally friendly. The pumps are lownoise, and the liquid ring technology emits only steam, as opposed to the harmful oil fumes emitted by rotary vane pumps. For many years, we ve had the circulator pump manufacturer Grundfos as a customer. We clean underneath the casting machines in their foundry, where the company manufactures aluminum pump cases. The production process leaves tiny aluminum chips and flakes, and it is our job to vacuum up and dispose of the mess. Grundfos is a company that places great importance on both the working environment and the environment in general, so using Samson s eco-friendly liquid ring pumps here is beneficial, says Brian, who has no doubt that the next pumps he will buy will also be Samson models. Some of the big manufacturers of rotary vane pumps have also begun producing liquid ring pumps, but from what I ve heard from my colleagues, they don t work particularly well. It s also an entirely new area for them, while Samson Pumps has been producing liquid ring pumps since 1955 and benefits from the enormous amount of knowledge and experience this gives. So, I m sticking with Samson, of course Brian concludes, Samson Pumps has been producing liquid ring pumps since 1955 and benefits from the enormous amount of knowledge and experience this gives

10 10 Pumps in action The Vacuum Journal Vacuum Trucks Liquid ring pumps ideal for city jobs Samson s liquid ring pumps are practically noiseless. This is, of course, a big advantage for the workers operating the pumps, but also for the people who live and work in the surrounding area. Billedtekst ind her, The environment and working area also benefit when we use Samson pumps. Because the pumps are water-based, they only emit harmless steam, which evaporates quickly and doesn t bother the operator Pumps in action Ulrik Sinding, owner of Djursland Kloakservice ApS (a sewage service company in Trustrup, Denmark) was practically born into the vacuum tanker business. Already in 1979, as a 15-year-old, he was hired by the company that his father, Orla Sinding, started in In 1989, at the age of 25, Ulrik Sinding took over the company, which has installed Samson pumps in most of its vacuum tanker trucks., I give Samson s liquid ring pumps my seal of approval I give Samson s liquid ring pumps my seal of approval. Here at the company, we ve only had good and positive experiences with Samson pumps. They re sturdy, durable and highly reliable, as well as quiet and environmentally friendly. Those are a whole lot of advantages, so I can highly recommend Samson pumps to any of my colleagues who ask me for advice, Ulrik says. Customers from a wide geographic area Djursland Kloakservice carries out vacuum tanker jobs throughout Djursland, a region located in the north of Denmark, as well as in larger cities such as Aarhus, Randers and Silkeborg, which are, respectively, 32, 34 and 57 miles from the company headquarters in the village of Trustrup. Djursland Kloakservice ApS serves private customers, companies and the public sector. The company has signed a contract with the municipalities of North and South Djursland involving the emptying of some 12,000 settling tanks (septic tanks) in the two municipalities. Well suited for use in cities One of our 10 vacuum tanker trucks runs regularly for the Danish construction group Aarsleff s division that carries out curedin-place pipe lining, a technique used to repair leaky sewers. Here, we flush and empty the sewers to remove sludge and waste before the cured-in-place lining is led through. This work is often done in cities, where the Samson pumps come into their own. Compared to rotary vane pumps, which make far too much noise while running, Samson s liquid ring pumps are practically noiseless. This is, of course, a big advantage for the workers operating the pumps, but also for the people who live and work in the surrounding area. The environment and working area also benefit when we use Samson pumps. Because the pumps are water-based, they only emit harmless steam, which evaporates quickly and doesn t bother, The environment and working area also benefit when we use Samson pumps the operator. Oil-based rotary vane pumps, on the other hand, emit oil fumes that cause problems for both the operator and the surrounding environment. If the vacuum tanker truck is parked next to a building, the oil fumes can stain the wall. If a rotary vane pump has a downwardfacing exhaust, the oil fumes settle like a film that looks awful and can damage the asphalt. We can avoid this type of trouble and damage by using liquid ring pumps from Samson, Ulrik explains.

11 Vacuum Trucks The Vacuum Journal Pumps in action 11, We only very rarely have breakdowns with a Samson pump, and if something actually does happen, it s usually only a minor issue that we can fix ourselves Oil-based rotary vane pumps emit oil fumes that cause problems for both the operator and the surrounding environment. This can be avoided by using liquid ring pumps. The fact that Samson pumps are incredibly reliable is very important to Ulrik Sinding. Getting a vacuum tanker to run properly is a costly matter when such a vehicle can cost more than $400,000. For this reason, high reliability is golden. We only very rarely have breakdowns with a Samson pump, and if something actually does happen, it s usually only a minor issue that we can fix ourselves. For example, if we re cleaning up slurry or molasses, which creates a lot of foam, nothing goes wrong with a Samson liquid ring pump. It simply spits the foam out as soon as it s created. When a rotary vane pump is exposed to foam, however, it immediately makes the dreaded ping noise! And then the pump s working day is over, Ulrik explains. Pump from 1996 still running Djursland Kloakservice ApS purchased its first Samson pump in 1996, and it s still running today, just not in Djursland. The company has a policy of replacing its vacuum tanker trucks after around 12 years of service. The vacuum tanker was thus sold to a colleague who still uses the vehicle and the incredibly durable Samson pump on a daily basis. A few years ago, Ulrik began offering dry matter vacuuming, such as the removal of ash from combustion plants. As of yet, he is not sure if there will be enough work to purchase a dedicated and expensive dry matter vacuum. He therefore decided initially to fit a vacuum tanker truck with two Samson KS1025 pumps. This proved to be an effective solution, and a high number of orders quickly came in so many, in fact, that after a couple of years there was a basis for investing in a costly mammoth vacuum that is designed on a completely different pumping principle than Samson s liquid ring pumps. Today we re doing a lot of work with dry matter suction, which has become an important business area for us. And it was the strong and effective pumps from Samson that made it possible for us to move into this area, Ulrik notes., Today we re doing a lot of work with dry matter suction, which has become an important business area for us Ulrik Sinding, Djursland Kloakservice ApS
