AP 15 Hygienic Diaphragm Pump

The AP 15 Hygienic Diaphragm Pump, a hygienic-grade air-operated diaphragm pump, is available with a 1½" (38 mm) Tri-Clamp connection; its capacity range is 0–400 liters per minute.

Its operating principle relies on compressed air alternately moving two diaphragms; this seal-less design eliminates the risk of leakage. The pump is self-priming, resistant to dry running, and its flow rate can be continuously adjusted via air pressure.

The pump housing is made of 316L stainless steel; Teflon, Santoprene, and EPDM options are available for the diaphragm and internal components in contact with the fluid.

The appropriate combination can be selected based on the pumped chemical; the stainless steel option is preferred for corrosive liquids and processes requiring hygiene; the Teflon diaphragm option allows for use with aggressive solvents.

It offers a discharge head of 0–84 mss and a suction lift of 6–8 m; it can handle fluids containing solid particles up to 6 mm in size.

The operating air pressure is 0–8.4 bar, the air connection is 3/4", and the air consumption is specified as 16–85 m³/h.

In the series designed for hygiene-sensitive processes such as food, pharmaceuticals, and cosmetics, Tri-Clamp connections can be disassembled without tools, enabling quick cleaning.
