Tapflo PE / PTFE air-operated diaphragm pump, up to 820 L/min, 8 bar, for acids and solvents

Tapflo PE & PTFE are industrial air-operated double diaphragm (AODD) pumps with a body machined from a solid block of polyethylene or virgin PTFE. No electrical supply is needed: the pump is driven by compressed air and the air distribution system is oil-free.

The design allows dry running, operation against a closed discharge without damaging the diaphragms, and handling of liquids with solids of 3–15 mm depending on size. Self-priming up to 5 m from a dry line and up to 8 m from a wet line. Ports can be rotated by 180°, the part count is low and service is quick.

Sizes: TR09 (11 L/min, 1/4"), TR20 (24 L/min, 3/8"), T50 (60 L/min, 1/2"), T100 (125 L/min, 1"), T200 (330 L/min, 1 1/2"), T400 (570 L/min, 2"), T800 (820 L/min, 3"). For ATEX 2014/34/EU zone 1, antistatic PE/PTFE pumps of the TX series are available.
