Plastic Diaphragm Pumps

To meet abrasive and corrosion resistant requirements, the Crest Pump’s range of DEPA plastic diaphragm pumps have been developed to utilise non-metallic materials such as polypropylene, PVDF or PTFE to ensure your process operates efficiently and reliably against the toughest applications.

The developments of the Series P plastic diaphragm pumps offer a combination of modern industrial design, combined with the daily requirements of pumps, like temperature, chemical resistance and high mechanical strength. The computer-aided design of the injection molding achieves a consistent high quality with an excellent surface finish for low flow resistance and good abrasion resistance. The result of the design offers a strong and compact diaphragm pump.

DEPA plastic diaphragm pumps have been developed to transfer a wide span of corrosive liquids, slurries, pastes and sludges for which pumps of metal construction fail to offer the necessary chemical resistance.
