For higher head applications when pumping corrosive acids and chemicals, PPM chemical pumps are the ideal choice. Usually for high head / low flow applications the user is forced to compromise by using a large pump with a suitably oversized impeller which will operate at the left hand side of the pump curve - this results in increased costs both initially by selecting a pump and motor which is capable of a considerably larger flow and also in increased running costs because a larger than necessary motor is used.

PPM chemical pumps are an extension of our existing and well proven PP range but are available with either two or three stages. The liquid is pumped from stage to stage so increasing the discharge pressure whilst maintaining the flow rate.

For each Crest acid pump, the wetted parts are machined from solid plastic for the ultimate in corrosion resistance and mechanical strength. A wide range of mechanical seals and motors can be fitted to suit most specifications.

For self priming applications suction priming chambers can be fitted giving suction lifts of up to 4 metres.
