Electrically operated diaphragm pumps

The Tapflo EODD pump series gently pumps the most aggressive media, is self-priming and sealless. Electric double diaphragm pumps withstand abrasive particles and even dry running.

Materials of wetted parts: Aluminium, PTFE coated aluminium, Stainless steel (industrial and hygienic), Plastic (PE & PTFE)

Diaphragm and ball materials: PTFE, TFM modified PTFE, EPDM, NBR, FKM Up to 220 l/min Up to 4 bar

Options: Pressure switch, Built-on frequency inverter.

Typical applications

Chemical industry
Surface conditioning
Water treatment
Paint, print industry
Pulp and paper industry
Hygienic applications
Mechanical industry
Varnish industry

Features & Benefits

Low energy cost. Electricity cost < compressed air cost, high efficient (IE3 class) drive
Long diaphragm lifetime. Pneumatic and mechanical support of the diaphragm
Run dry without damage. Easy to use, no need of guarding device
Low spare parts cost. Electric Diaphragm pump has an almost identical design of the wetted side as the standard Tapflo air operated diaphragm pump, therefore many spare parts are the same
Self-priming from dry suction pipe. More options of installation
Clean & easy maintenance. No hydraulic fluid required, no danger of leakage
Few components & long life design. Low downtime and maintenance cost
