Diaphragm Pumps Ltd

Depa_P Air Operated Double Diaphragm (AODD) Pumps are becoming the most common pumps for use when Only Air is available or when pumping solid laden liquids or slurries. Depa_P Diaphragm Pumps have no seals as the diaphragm acts as the barrier between the Liquid side and the drive side of the pump. When the liquid pressure reaches the air pressure, the Depa_P pump reaches a point of balance and stalls without the need for bypasses or overload protection.Depa_P Diaphragm Pumps pump can run dry indefinately and have the ability to self prime to 7 metres or more in some cases. They can handle viscosities up to 20000 Centipoise as standard and some Depa_P models can handle cPs into the 100's of 1000's. Depa_P Pumps are some of the most reliable AOD's in the marketplace, Self Priming, Dry running, Intrinsically safe, these are just a few of the features of Depa_P Diaphragm Pumps. Models include pumps for pumping hygienic products, aggressive chemicals aswell as standard industrial duties. High pressure models are also available for filter press applications or for pumping into closed systems. ATEX regulated Depa_P pumps are offered for Zone 1 environments. Depa_P Pumps and spares are available from Diaphragm Pumps Ltd, Stoke On Trent, England. As one of the largest stockists of pumps and spares in Europe, we hope we can supply all your Depa_P Pump needs.

DEPA P Type- Plastic Pumps

DEPA Plastic Pumps

The DEPA P Type series are made of mechanically manufactured or specially injection moulded plastic parts and were designed for problem free pumping of corrosive and abrasive materials in galvanic applications, in the chemical industry and in mechanical engineering.

By using computer aided injection methods a high quality surface finish is achieved, which ensures low flow losses and excellent abrasion resistance.

Despite the compact construction this design offers high mechanical stability. Pumps constructed of electrically conductive plastic materials enhance the product range. These enable the conveyance of non-conductive products in explosion endangered environments.

The wide range of construction materials available enables the universal use of these pump. A choice can be made between internal and external mounted air control valves. ANSI, DIN and JIS flanges as well as threaded connections are alternatively available. Product contact parts (diaphragms, valve seats and balls) are available in a selection of materials to ensure compatibility with a wide range of pumped media.
