Depa Air Driven Diaphragm Pumps

Series M Type DL
Cast Metal Pumps

For general industrial, water/ waste, construction and mining duties.

1 Many years experience in the design and manufacture of air driven diaphragm pumps have resulted in these high performance units. Because of their compact, lightweight construction, they are well suited to portable and mobile applications as well as fixed installation in process plants.

All types of fluids from water to slurries and pastes, including abrasive or shear sensitive media containing solids, are handled cost effectively by these pumps.

1Choice of just the right Series M unit to satisfy the requirement in each case is facilitated by availability of three different materials for the pump housing:

  • Cast Aluminium, AL 233
  • Ductile Iron, GGG 40
  • Cast Stainless Steel, 1.4408 (SS 316)

Series M pumps are manufactured in five different sizes with standard connections: DN 15 to DN 80

All models are completely self contained, only requiring connection to pipework and air supply.

Standard design

Features include maintenance free control valve, stainless steel base with integral anti vibration mounts, drain and vent connections, stainless steel clamp bands, air intake filter (for DL25 to DL80) and muffler.

Accessories

A complete range of accessories simplifies operation and enhances flexibility.

They include pulsation dampeners, monitoring and control systems, various transport devices, quick release couplings, adapters etc.
