  • Sizing and Selecting Metering Pumps

    2019-10-10 · Metering pump flow rate can be manually adjusted by a micrometer dial. Adjusting this dial changes the pump’s stroke length and allows the pump to be operated anywhere between 10% and 100% of its rated flow capacity. Metering pumps with micrometer dials may also feature a variable speed drive that allows adjustment of the pump’s . stroke speed.

  • Metering Pump Principles | Milton Roy

    Flow Adjustments – Pump flow rate is adjustable by varying stroke length, effective stroke length, or stroking speed. Most metering pumps are supplied with a micrometer screw adjustment similar to the one shown here. The micrometer can also be replaced by an electronic or pneumatic actuator to adjust pump flow rate in response to process signal.

  • Pulsafeeder Diaphragm Metering Pumps

    2014-1-6 · The flow rate of a metering pump can generally be adjusted in one of two ways. The user can vary the distance that the piston travels, or the speed at which it reciprocates within the pump. For changes in the piston travel, or stroke length, a mechanical adjustment within the pump is used.
