Tapflo EODD electric diaphragm pump, up to 250 L/min, 4 bar, no compressor needed

Tapflo electric diaphragm pumps replace the classic AODD where there is no compressor or compressed air is too expensive. The drive is a geared motor with diaphragm hydraulics: no mechanical seal and no hydraulic oil in the wetted area.

Flow up to 15 m³/h (250 L/min), working pressure up to 4 bar, temperature up to 110 °C. Bodies: PE, PTFE, aluminium, PTFE-coated aluminium, AISI 316L. Diaphragms PTFE, EPDM, NBR, FKM and white food-grade versions.

Certificates: ATEX zone 1 in the Ex version, FDA and USP VI optional, REACH, RoHS. Energy consumption is lower than with air drive; the pump tolerates dry running, diaphragm life is long and the part count is low.

Key features:

• Electric drive — no compressor needed
• Lower energy use than air-operated pumps
• Dry running, no oil leaks
• PE, PTFE, aluminium, AISI 316L bodies
• Long diaphragm life, few parts
