Diaphragm Pumps Ltd. products

The Murzan PI 50 is the only diaphragm pump specifically designed to meet the special requirements of the sanitary industry. High efficiency oil free air valve, maintenance free ball check system or flap check valve and total visual inspection of all wetted parts, give the user safe and efficient transfer of foods, cosmetics and pharmaceuticals - USDA listed, FDA approved, the PI 50 Series is manufactured to meet general 3-A Standards.

Diaphragm Pumps offer a large range of hygienic pumps from stock. These include models with FDA, 3A, USDA and EHEDG certification.
Diaphragm Pumps can handle a large range of products gently and with minimal shear. This gentle handling makes them ideal for products with fruit or vegetable particulates e.g. Chutney or Jam. The ability to CIP (Clean in place) or SIP (Steam in place) makes them ideal for processes which change regularly e.g. Yoghurt where there may be a batch of one flavour followed by a rinse then another flavour. Of course these pump can also be dismantled for cleaning with little or no tools required and assembly/disassembly is very quick.

The Air filter is used to restrict any particulate matter and water from entering the air valve on the pump. The particulate can jam the shuttle or act abrasively widening the tolerances which reduce efficiency and eventually cause air slippage around the shuttle. The presence of water in the air valve mixing with the required lubricant can create an emulsion causing resistance and stalling in the shuttle, also excessive water entering into the pump air chamber can cause off centre loading on the shaft which causes early failure of the shaft and `O` rings.

More than 20 models with different sizes and designs are available in the DEPA M Type range. The sturdy cast metal construction ensures high abrasion resistance when pumping abrasive media, a low flow resistance due to the high surface finish, availability throughout a wide temperature range, excellent corrosion resistance and a long lifetime.

The Husky 515 and Husky 716 pumps operate from 25-100 psi (1.8 - 7 bar) and pump fluids with viscosities of up to 5,000 cps, and pumpable solids up to 3/32 in. (2.4 mm) in diameter.
