Wilden High-Pressure AODD Pumps Ideal for Handling Resins, Solvents and Additives in Paint & Coatings Applications

Press release date: February 13, 2013

Grand Terrace, CA – Wilden, the worldwide leader in air-operated double-diaphragm (AODD) pump technology, is pleased to announce that the High-Pressure models of its Advanced™ Series Metal Air-Operated Double-Diaphragm (AODD) Pumps feature operational capabilities that make them ideal for the loading, unloading and transfer of resins, solvents and additives in Paint & Coatings manufacturing applications.

Specifically, Wilden High-Pressure AODD Pumps can generate up to 20.7 bar of pressure (300 psi), which is a core requirement for the reliable transfer of Paint & Coatings resins, solvents and additives that are viscous or solid-laden. Wilden offers three models of Advanced High-Pressure AODD Pumps:

• H200: This 25mm (1”) duplex pump uses both liquid chambers to pump fluid. It is constructed of ductile iron and creates a 3:1 pressure ratio with a maximum inlet air pressure of 6.9 bar (100 psi) and maximum discharge pressure of 20.7 bar (300 psi) while delivering flow rates up to 94 L/min (25 gpm). It can handle solids up to 6.4mm (1/4”) at operating temperatures to 225F (107C).

• H400S: This 38mm (1-1/2”) simplex pump uses only one liquid chamber to pump fluid while the second is used as a pressure-amplification chamber. It is constructed of aluminum or stainless steel and creates a 2:1 pressure ratio with a maximum air inlet pressure of 8.6 bar (250 psi) and maximum discharge pressure of 17.2 bar (250 psi) while delivering flow rates up to 242 L/min (64 gpm). It can handle solids up to 8mm (5/16”) at operating temperatures to 225F (107C).

• H800: This 51mm (2”) duplex pump uses both liquid chambers to pump fluid. It is constructed of stainless steel or ductile iron and creates a 3:1 pressure ratio with a maximum air inlet pressure of 5.9 bar (85 psi) and maximum discharge pressure of 17.2 bar (250 psi) while delivering flow rates up to 359 L/min (95 gpm). It can handle solids up to 12.7mm (1/2”) at operating temperatures to 225F (107C).

All three models are available with Wil-Flex™ Diaphragms, which are ideal for resin, solvent and additive transfer. Wil-Flex diaphragms feature a flat-profile design that eliminates the need to invert the diaphragm when rebuilding a pump, which allows for easy, cost-effective installation and maintenance, along with increased flex life.
