Motor Driven Metering Pump

HAOSH motor-driven metering pumps are able to operate on their own without supervision. The eccentric cam mechanism converts the rotational motion of the motor into a reciprocating motion, allowing the volume displacement to deliver fluid at a constant rate.

Metering pumps with mechanically driven diaphragms can be used almost universally in the low pressure range. This type is used in applications where durability is critical, such as those requiring 100% duty cycle or those involving critical processes where pulsation is not an issue.

how does a motor driven metering pump work?

Motor-driven metering pumps are powered by an electric motor and have a controller that manages the flow rate. This type of chemical metering pump uses a reciprocating diaphragm with a flexible diaphragm inside that creates suction to move fluid into and out of the chamber.

Types of motor-driven metering pumps

Industry applications

  • Disinfectants in drinking water treatment
  • Disinfectants in cooling circuits
  • Flocculants in wastewater treatment
  • Auxiliaries in the paper industry
  • Additives in plastic manufacturing



Motor-driven metering pumps. Because it has the most universal application and can operate autonomously and reliably for long periods of time.

Positive displacement pumps can handle highly viscous fluids, and their flow rates can increase as the fluid thickens. On the other hand, centrifugal pumps cannot handle viscous fluids due to frictional losses.
