The food grade PF50 one-inch air-operated double diaphragm pump (AODD) is constructed from 316 stainless-steel with PTFE diaphragms, PTFE ball valves and PTFE gaskets. For high viscosity fluids, you may require heavier, stainless-steel ball valves so please search for product number PPF0050S-HTSST3-AB.

This little food grade diaphragm pump is ideal for a range of fluid transfer duties up to 55 litres per minute (based on water) and is a good option for the dosing and metering of fluids. The PF50 weighs approximately 7kg and with its easy to strip-clean design, the Fluimac Phoenix Food PF50 is versatile and simple to operate.

The PF50 will soon be superseded by the new PF60 – launching September 2020.
