HDA-Product Line
HDA&HDR Heavy Duty Slurry Pump Specs
HDA&HDR derived from warman pump’s AH series. Through the improvement of material and structure by our experienced engineers, HDA and HDR series have higher efficiency in pumping solids, more wear resistance and longer service life than warman AH series.
Clear Water Performance
Remark:
1. Capacity range recommended: 50%Q’≤Q≤110%Q’(Q’ Appropriate to capacity at highest efficiency point).
2. NPSH: appropriate to point Q recommended at highest speed
Metal materials for wet parts
We provide a variety of Metal materials for wet parts which can be used in different operating environments to improve the efficiency of the slurry pump.
Rubber materials for wet parts
The use of rubber material for wet parts extends the wear life of the pump and makes it easier to replace worn parts of the pump.Hedun offers a wide range of rubber wet parts material to meet the needs of different application scenarios.
Main Applications
This kind of slurry pump mainly applies in coal washer processing, handling with the fine ore and tailings in metal mine, handing combined bottom and fly ash in a thermal power station etc.
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.
