Diaphragm Pumps See all Applications

diaphragm pumps

Air operated diaphragms pumps (also known as pneumatic diaphragm pumps, AODD pumps, AOD pumps) are used for endless applications in mining, industrial and general plant service. Air operated diaphragm pumps are especially used where electricity isn’t available, or in explosive or flammable areas. They are also used for chemical transfer, de-watering underground coal mines, food manufacturing or where the liquid being pumped has a high solids content or high viscosity.

How AOD Pump Works
 

Air operated diaphragm pumps are a type of reciprocating diaphragm pump which contains two diaphragms driven by compressed air. Air section with shuttle valve applies air alternately to the two diaphragms, each diaphragm has a set of check/ball valves.

The premier manufacturer of air operated diaphragm pumps is Graco with which All Pumps has had a long association.

almatec pumps

ALMATEC manufacture a range of air-operated double diaphragm pumps with a wide range of products, including their popular E-SERIES with a solid metal or plastic housing. Plastic materials used are PE, which is highly resistant to abrasion and PTFE which has resistance to virtually all chemicals, and can be used in explosion proof areas and with flammable liquids. The metal pumps are made of precision-cast stainless steel and primarily used in the chemical, pharmaceutical and biochemical industries. Almatec pumps are often deployed in applications such as handling of ultrapure liquids, paint and glue supply systems, filter press feeding, sterile applications, laboratory and sample pulling. Almatec is manufactured by Wilden.

All Pumps has been importing, servicing and supplying Almatec pumps in Australia for 10 years and support the full Almatec range of pumps and spare parts.
