25 APPLICATIONS Damen developed, in cooperation with various dredging contractors, a series of multi-functional submersible dredge pumps, the DOP pumps. The heart of this versatile dredge tool is a wear-resistant, compactly built dredge pump with a maintenance-friendly seal. All wear parts can easily be replaced and, depending on the job, supplied in different materials varying in hardness, toughness and price. Damen has more than 60 years of experience as a manufacturer and designer of dredging equipment. This knowledge enables us to design modifications for the DOP pump to suit your requirements as well as assist and advise you on the operation of the DOP pump. Sand and gravel mining dredging. Small scale dredging operations, such as maintenance dredging in ports and canals. in restricted areas. Unloading of hopper barges. Suspended from an A-frame as a deep suction dredger, down to a depth of 50 meters. Mounted on a cutter ladder. Suitable as a mobile booster station. Special applications such as environmental dredging. ADVANTAGES Proven design, already used by many contractors around the world. Operating depth down to 500 meter. Multifunctional, basic pump unit can be outfitted with various suction heads for specific purposes. Executed with heavy duty mechanical seal which does not require glandwater or grease supply. Discharge distances up to 1000 meter with a single pump. Sphere passage impeller up to 200 mm. Heavy duty construction with protective casing to allow operation in rough environments. Different sizes to suit client requirements. Very high production capacities. Changeable wearing parts made of high wear resistant material. Available with hydraulic as well as electric drive.

Discharge hoses or pipelines, floaters, jet-water hoses, hydraulic hoses to drive the DOP pump as well as the cutter unit. Diesel driven powerpack or generator set to drive the DOP pump with the following accessories: additional hydraulic drive for cutter unit; jet water pump; sound reducing casing. Control and monitoring equipment: revolution counter; vacuum/pressure indicator; depth meter; mixture velocity meter; mixture concentration meter; production meter; materials.

27 Suspended from a crane and equipped with a jet water ring, DOP pumps are used for emptying barges. Suspended from an A-frame and equipped with a sand production head, DOP pumps transform a pontoon into a sand suction dredger. In combination with a hydraulic power pack, DOP pumps are deployed as trouble- shooters at various sites for short periods. MULTIFUNCTIONAL Both deep suction dredging and cutter suction dredging with the same suction dredger is made possible by using a DOP pump. Mounted to a hydraulic excavator using a quick coupling and equipped with a cutter unit, DOP pumps cut trenches for pipelines and level workpits. A DOP pump equipped with an auger head in combination with a backhoe pontoon is a perfect dredger for environmental dredging operations. The auger head cleans up wide tracks on an accurate depth and the turbidity is minimal which is necessary when dredging polluted material.
