1 HDS Centrifugal Slurry pumps We re with you every step of the way The HDS series pump is a heavy duty pump that is designed to handle the most abrasive and dense slurries. The HDS series pump offers users a wide range of seal and liner configurations, allowing the pump to be fully customised to meet our customer s specific application requirements. HDS series pump design features 2 years of pump manufacturing and design experience In addition to this wealth of experience, we have used the latest and most advanced computer aided engineering software, to ensure that we offer our customers the best performance, longevity and reliability under the toughest conditions. Bearing assemblies The large diameter shaft uses a unique oil bathed cylindrical bearing to ensure unsurpassed service life and reliability. Only four bolts are required to hold the housing frame in place, further enhancing serviceability and maximising uptime. Discharge outlet The discharge outlet of the HDS series pump has eight (8) positions at 4 degree intervals that can be selected to best meet application and installation requirements.

2 Waterproof cover prevents water entering the transmission housing Protective gland prevents water & foreign matter from entering the bearing housing Additional protection to reduce maintenance and increase component life Seals - The HDS series pump provides customers with a variety of seal options to meet a broad range of operating conditions and customer specific requirements. Please see the following illustrations for some of the sealing options that are available; Mechanical Seal HDS series pumps utilises a world-leading leakproof mechanical seal design, that allows for easy installation and replacement. This seal configuration is suitable for the toughest conditions. We utilise special ceramic and alloys of high strength and hardness on parts that are subjected to heavy friction. Amongst the many characteristics of this seal design, is its excellent resistance to abrasivity and shock that ensures its effectiveness under the toughest conditions.

Seals can be made of polytetrafluoroethylene, graphite and other materials depending on the application. For high abrasion conditions, a ceramic shaft sleave is available. Helix L Rubber Seal The shaft seal of the HDS slurry pumps utilises a spiral L shape rubber seal that consists of three (3) L-shaped seal rings and one (1) shaft sleeve with a special thread. 1 Packing Box 2 Front Lantern Ring 3 Packing 4 Packing Gland Shaft Sleeve Packing Seal Arrangement 1 Flange End Cover Gland 2 Shaft Sleeve 6 Spring 3 Sealing Ring Pad 7 Sealing Ring 4 Pipe Nipple 8 Screw

3 Material Research Centrifugal slurry pumps are widely used to transport solids and liquids across many industries such as metalliferous mining, coal mining, electric power plants, the chemical Industry, the food Industry, sewage treatment plants, and channel dredging to name a few. Slurry pumps play a vital role in all of their applications and must efficiently and economically satisfy the production, serviceability and durability requirements of both the customer and the application. Due to the broad and stringent requirements for quality and performance, we have spent considerable time and effort in researching and testing materials and improved pump designs to ensure that our pumps and components offer the best service life possible. The Series K range of materials can be adapted to meet any type of application and specific wear requirements. Series K materials include anti-corrosive, anti-wear, alloys, metals and non metallic items. Only the best and most suitable materials have been incorporated into the design of the HDS series pumps. We are fully committed to providing quality products that are easy to service and maintain and that offer excellent performance and durability under all conditions.

This material can be drilled and tapped This material has erosive and corrosive resistance in low ph applications. Its wear resistance is similar to KB02 This material has similar erosion resistance to KB02 and also has good corrosion resistance This material has is of high harness and has good antierosion properties Mild harness material with antiwear and anticorrosion resistance. This material is weldable APPLICATION Used for high wear applications with a ph between and 12 Used for high wear applications Used for mud pumps Used for mid wear applications with fine grain medium Used for low ph applications of less than 4. This material is particularly suitable for flue gas desulphurisation (FGD) and other mild acidic applications This material can be used to transport oxygenated slurries with ph of not less than 1 such as phosphorplaster, nitric acid, vitriol, phosphate etc Used in high wear, high erosion and high corrosion applications Used for mild erosion wear applications such transporting water medium with fine granular particles
