Why The Wilden Air Operated Diaphragm Pump is a Flexible Choice


The first air operated diaphragm pump was invented by Jim Wilden as unique but reliable,
utilitarian pump. He founded Wilden Pump and Engineering in 1955 and the air operated
diaphragm pump was launched. The pump since then has been copied and redesigned over
the years, but the basic principle remains the same — reciprocating action of the diaphragms
provides suction in one direction and pressure in the reverse.

 The air operated diaphragm pump is a work horse and offers many benefits. For example:


Flexible operation

 

The diaphragm pump can self prime, and if the parts are wetted lift up to 29
ft.. The pump can run dry too. If someone starts the pump and gets called away forgetting to turn
the pump off, it's no problem. The pump will continue to run even with no fluid flowing without any
adverse side affects. The pump will stop (dead head) if the discharge valve is closed or the system
pressure increases above the pump air supply pressure.

This makes it the perfect pump to use on filter press applications. The air operated diaphragm pump can be submerged in a sump or placed in hazardous areas where ex-proof equipment is required. (Make sure you let your supplier know these requirements).

Flexible material options

 

The pump can be made from a variety of materials. The wetted path can be cast
iron, aluminum, stainless steel, Hastelloy, Polypropylene and Kynar. There are multiple
elastomer options such as Buna-N, Neoprene, EPDM, Viton, and there are even thermoplastic options like Polyurethane, Wilflex (polyurethane & EPDM), Geolast (polyurethane & Buna-N), and Teflon.
Most of these options are offered in food grade too. 

The 316 stainless steel components can be ordered with a
high polish finish meeting EHEDG standards, and the materials can be assembled in any
configuration necessary to handle clean, dirty fluids, chemicals, abrasive, caustics, acids,
viscous, oils, foods, beverages, bio-pharm solutions.

 

Flexible installation  

 

The pumps can be in a fixed location as part of the system or mounted on
a portable cart easily moved from one location to another inside the plant. The pump can be
trailer mounted as is often done for driveway sealing too.

Easy to Repair


Finally, air operated diaphragm pumps are easy to repair. There are few moving parts and with
simple hand tools just about anyone can disassemble, replace parts, and reassemble the pump.
