Metering pumps include, but are not limited to:

  • Acid dosing pumps
  • Caustic dosing pumps
  • Chemical dosing pumps
  • Digital dosing pumps

Solenoid Pump Configurations

A Solenoid-Driven Metering Pump is a pump that uses an electromagnet as the driving power. When this pump is energised, the electromagnet attracts the solenoid plunger, generating a reciprocating motion moving the diaphragm to deliver a pre-determined amount of fluid.

Motor Driven Pump Configurations

A Motor-Driven Metering Pump is when the rotary motion of the motor is converted to reciprocating motion by the eccentric cam mechanism which, causes the volume displacement to transfer the fluid at a constant rate.  Motor dosing pumps are recommended when high performances are required.
