Advantage of HDA&HDR Slurry Pumps

Heavy duty construction with through-bolt design provides ease of maintenance and minimal downtime
Ductile iron fully lined casing provides durability, strength, safety and long service life
Large diameter, slow turning, high efficiency impellers designed to achieve maximum wear life and low operating costs
Large, open internal passages designed to reduce internal velocities, maximise wear life and lower operating costs
Thick elastomer or alloy bolt-in liners provide superior corrosion resistance plus offer ease of liner change-out and interchangeability to reduce overall maintenance costs and maximise wear life

Minimal shaft/impeller overhang reduces shaft deflection and increases packing life
Cartridge-style bearing assembly allows for maintenance in a clean environment without removal of the pump, resulting in reliable operation and prolonged bearing life
Grease or oil lubrication bearing assembly options offer ease of maintenance and reduced downtime
Now featuring Hedunpumps throatbush and impeller combination designed to enhance efficiency and improve wear performance

Other Benifits of Heavy Duty HDA/HDA Slurry Pumps

Replaceable Wear-resistant Liners

The HDA slurry pump frame plates have wear-resistant replaceable metal liners and the impellers are made of wear-resistant metal. HDA slurry pump’s frame plates and liners can only be made of hard metal. Compared to HDA, HDR type pumps can use not only metal but also rubber to make liners and other wet parts.

Cylindrical Structure

Bearing assembly of this kind of slurry pump use cylindrical structure, adjusting the space between impeller and front liner easily, being removed completely when being repaired. Bearing assembly use grease lubrication.

Great Performance

Wide performance, good NPSH and high efficiency are main character of these kinds of slurry pump. The pump of this type may be installed in multistage series to meet the delivery for long distance.

Different Applications

The discharge branch can be positioned at intervals of 45 degrees by request and oriented to any eight positions to suit installations and applications.

Multi Seal Methods

The shaft seal of this kind of slurry pump could use the packing seal, expeller seal and mechanical seal.

Multi Drive Type

Here are the drive types, such as V belt drive, gear reducer drive, fluid coupling drive, and frequency conversion drive devices.
