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

52 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.

Discharge outlet – The discharge outlet of the

HDS series pump has eight (8) positions at 45

degree intervals that can be selected to best

meet application and installation requirements.

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.

Oil bathed cylindrical bearings

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;

Expeller Dynamic Seal

Packing Seal This sealing system is suitable for a wide range of applications and can be used in high corrosion and high temperature applications. Seals can be made of polytetrafluoroethylene, graphite and other materials depending on the application. For high abrasion conditions, a ceramic shaft sleave is available.

Packing Seal Arrangement

Mechanical Seal

HDS series pumps utilises a world-leading leak-

proof 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.

Helix L Rubber Seal

The shaft seal of the HDS600 – 1000 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.

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.
