DEWATERING

DW PUMP

Description

Available in 150mm and 200mm discharge sizes. These pumps can achieve 13 bar pressure at 290 l/s with best efficiency 78%. They are designed to withstand working pressure of 50bar and are statically tested at 75bar and are therefore safe and efficient in series pump configurations. Larger vein sizes decrease probability of clogging.

Design Features

1000 m3/hr B.E.P @ 120 meter head. Specific Gravity 1.05
Volute Casing test pressure 7500 kpa. Working pressure 5000 kpa.
Longevity is achieved with unique sealing and bearing design resulting in minimum delays and standing time.
These significant improvements have reduced the total cost of ownership to company with case studies to prove these claims.

VS Range

Description

Heavy Duty Hard Metal or Elastomer – This has been enhanced from the original design with the hydro-dynamic expeller labyrinth seal which when operating pressurizes and keeps contaminants from entering the bearings.

Design Features

Due to the OEM design weaknesses, we introduced our design improvements that have increased the working life of this pump significantly resulting in huge cost savings.
A PRZ Hydro-dynamic expeller labyrinth seal was introduced, the pressurized seal design keeps contaminants from entering the bearings with an additional shrink-on securing ring.
A heavy-duty five-foot column extension design for additional support.
A standard heavy-duty five-foot volute design to match.
The cantilever shaft design together with improved material selection enables high impact resistance from large pumped objects.
A complete test and Case study was conducted and concluded by a Mining Company quality department.
Monthly operating expense’s and improved overall cost of ownership have been achieved.
