500 Style polypropylene pumpsare made from solid blocks of plastic and are supported by metal domes, top and bottom plates, and through-studs to ensure safety and facilitate maintenance.

They are normally used for solvents, chemicals and dyes, and provide a less expensive alternative to stainless steel.

Max flow rate: 680 l/min
Pump inlet/outlet size: 3"
Diaphragm diameter: 14"

500 Style pumps are part of Flotronics F Series of air-operated double diaphragm pumps. These pumps are suitable for both simple transfer and continuous duty process applications using PTFE faced multi-million cycle diaphragms as standard.

PVC and PVDF versions are also available.

F Series pumps use Flotronics one-nut design. Each pump is held together by one nut on the opposite side of the pump to the external air valve.

This design allows in-line diaphragm replacement to be accomplished in less than 15 minutes, with a complete stripdown and rebuild possible in less than 20 minutes.
