Rugged & Robust

For pumping from tanks or sumps between 0.5 metres and 4.5 metres deep, Crest PPS Pumps are the best choice.

The design concept behind the PPS range is a reliable, heavy duty pump at a competitive price. This makes the PPS range totally rigid and vibration free, capable of giving many years of trouble free service.

Materials of construction include polypropylene, PVC and PVDF with bearings of ceramic and PTFE for optimum corrosion resistance.

Applications include:

Chemical processing
Effluent treatment
Metal finishing
Pollution control
Corrosive liquid transfer
Re-circulation within deep sumps or tanks

The wet ends are machined from solid plastics and the suspension system is fabricated from thick wall, heavy duty tube with integral stiffening bars to prevent longitudinal movement.

The stabilising PTFE and high alumina ceramic bearings are usually product lubricated, however, for liquids which contain a high degree of solids or abrasives, external flushing lines can easily be fitted.

The impeller can be either semi-open or fully enclosed depending upon the application, radial back-vanes machined on the impeller ensure a continuous and plentiful flow to lubricate the bottom slide bearings. A feature of Crest PPS pumps is the facility to adjust the impeller gap from above the mounting plate without having to remove the pump from the sump or tank.
