Depa Air Driven Diaphragm Pumps

Series P Type DL Non metallic pumps

For use with corrosive and abrasive media in chemical processing, electroplating, effluent treatment and similarly arduous applications.

1 DEPA Series P pumps with solid, non metallic components 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. The pump housings are machined from solid Polypropylene (PP) or Polytetrafluorethylene (PTFE).

1 The elaborate manufacturing process involved ensures the highest possible stability of form and thus the pumping pressure capability is maintained in line with standard DEPA cast metal pump versions. In addition, the solid PP and PTFE form also provides complete external resistance to corrosive environments.

Choice of correspondingly stable, corrosion resistant materials is available for the diaphragms, valve balls and valve seats.

These pumps can be supplied with connecting flanges conforming to DIN as well as ANSI standards.

An electrically conductive plastic pump build also allows transfer of non conductive media in explosive and/or hazardous areas.

Electrically conductive, non metallic DEPA pumps can be constructed of both PP and PTFE.

The pumps can be electrically earthed.

Standard design

Features include overall corrosion resistant construction, maintenance free control valve, stainless steel base with integral anti vibration mounts, stainless steel clamp bands, muffler, air intake filter and flange connection for models DL 25 to DL 80.

A complete range of accessories simplifies operation and enhances flexibility.

Accessories include pulsation dampeners, monitoring and control systems, various transport devices, quick release couplings and adapters. For spare parts or more information please contact us.

  • Designed for resistance to corrosive media and environments with rugged non metallic construction and components.
  • Ideal also for abrasive, viscous and shear sensitive media, and for products with entrained solids.
  • Air operation plus electrically conductive plastic housing means suitability for explosive or hazardous areas.
  • Tolerance of dry running and harsh usage.
  • Minimal maintenance with no lubrication required.
  • Positive displacement pumping action minimises product shear.
  • Completely enclosed units with no bearings or rotary seals in the product stream.
  • Easy control of flow rate by regulating air supply.
  • No need for electric motors, special drives or base plates.
  • Easily portable and ready to use by simply connecting to air supply.
  • Can be run against a closed discharge-a vital benefit for use on filling machines.
  • Self priming and submersible.
