4" 316SS WELLPUMPS HT submersible Leachate Pumps 60 Deg C
The established Well Pumps range of 4” borehole pumps - in 304 grade Stainless
Steel - has now been augmented by the addition of a new HT (high temperature)
version built with 316 stainless steel for harsh environments. The WPS-HT has
been specially designed for use in high temperature leachate pumping applications
up to 60°C. This has been achieved with the use of all 316 stainless steel materials
and the development of a special motor to operate at these elevated temperatures.
The elastomers are all in viton and the motor has a silicon / viton mechanical seal.
Anyone who uses pumps in aggressive environments will recognise the enhanced
corrosion resistance these materials give the units as a significant advance over
existing pump ranges.
Standard features of the WPS-HT include:
Robust construction using 1mm (minimum thickness) cold pressed stainless
steel sheet components.
6-spot welding on each impeller vane – 6-point contact between each impeller
and hexagonal shaft.
Special over-sized Viton rubber bearings, stainless steel-reinforced neck rings
and water-lubricated top bearing for excellent abrasion resistance.
Suitable for vertical or horizontal operation
Rugged clip-in cable guard ( no screws to lose )
Internal strainer
These qualities give users the opportunity to handle sea water and contaminated mine- or ground-water
together with a myriad of other industrial contaminants and the reassurance that the pump will give long,
reliable and efficient operation. The performance range on the WPS-HT is up to 4m3/h with heads up to
120m. 12m3/h flows can be achieved up to 65m.
Proquip can offer a full range of customised 316 SS or polymer shrouds and strainers for WPS-HT pumps
when used in vertical or upslope / incline risers. These shrouds draw liquid over the motor to maximize
cooling and extend pump life – each is custom fabricated to suit your specific application.
Performance Range:
- Flow rate up to 12 m³/hr Dynamic head up to 120 meters
- Motor rating up to 4 kW (4“ motor).
- Vertical and horizontal position of operation.
- Maximum fluid temperature +60°C
- Maximum allowable amount of sand: 50 g/m3
- All parts out of stainless steel AISI 316
- Performance Curve tolerance according to ISO 9906 Annex A
Pump Installations and Applications
