EFR Chemical Injection Pumps

EFR Chemical Injection Pumps


Process diaphragm and piston dosing pumps, positive return type. A non-loss-motion mechanism

  • Flow: 207-3200 l/h
  • Maximum pressure: 12 bar
  • High suction capacity
  • High accuracy
  • Stroke regulation with minimum flow pulsation
  • Heavy duty mechanism for continuous operation


The series EFR dosing pumps are positive return type, in piston or diaphragm for dosing liquid products.

EFR dosing pumps are available in one or two dosing heads, it allows many flow possibilities. The heads flows goes from 330 to 1600 l/h for the piston series, and from 207 to 1044 l/h for the diaphragm series.

The flow of each head is adjustable independently from 0% to 100% of its capacity with no need to stop the pump.

The non-loss-motion mechanism, with variable eccentric regulation produces a high accuracy dosing while smooth and safe operation.

EFR injection pumps are designed for continuous operation under heavy duty conditions with all kind of fluids, even highly viscous fluids, in applications such as water treatment, industrial processes and agriculture.
