Overview

Plastic Mechanically Sealed Pump Range
With over 40 years of experience, Crest Pumps have perfected the Plastic Mechanically Sealed Pump. Our technical and engineering knowledge has refined the mechanical seal range to be the most flexible, efficient and reliable pumps on the market.
Flexibility
Our mechanically sealed range have been designed to be fully flexible to ensure that the chemical pump will always fit perfectly within a new or existing system. Because the pumps are built in our British, specialist in-house manufacturing plant, we can build any pump to your exact requirements.
Part of our flexibility is including a range of different materials such as Polypropylene, PVC, PTFE, PVDF and 316 stainless steel for the pump to be customised in. (if required).
Experience
Crest Pumps began building our mechanical range from solid in 1973 and have continued to improve and enhance the specifications of the pump range to make the pumps even more efficient and reliable.
We have a great sense of pride when we receive an enquiry for spares in a Crest pump that was originally built over 25 years ago.

No obsolete parts policy

Crest ECC pumps come with a 'no obsolete part policy' which means even after 30 years of use, parts will be available or an exact replacement, minimising your downtime.

ECC Series PP Series PPM Series

The Crest range of PPM mechanical seal centrifugal pumps are designed to deal with some of the most corrosive and arduous, low flow – high head applications in the chemical industry. All wetted Crest PPM display imageparts are machined from solid blocks of plastic for the ultimate in robust construction. All pipeline forces are absorbed by a rugged steel shell.

For higher head applications – compatible for liquids ranging from caustic, to hydrofluoric acid – the PPM range of mechanical seal pumps are the ideal choice for reliable process pumping. Usually for low flow / high head applications, the user is forced to compromise efficiency and energy consumption for a larger pump with a suitable oversized impeller.

The PPM multi stage pump overcomes this unnecessary obstacle by providing an efficient and reliable alternative.
