Flow Control – Positive Displacement Pump Part 2
Terry Blevins
When using a positive displacement pump in flow control, then the minimum flow which may be achieved using a variable speed drive is limited by the motor low speed limit. It is possible to achieve a wider range of flow control by regulating flow using a fixed speed motor and a throttling valve in combination … Continue reading » Read the full text.

Flow Control – Positive Displacement Pump Part 1
Terry Blevins
Positive displacement pumps may be used when it is necessary address flow requirements of 2GPM or less. The pump design ( e.g. vane, gear, peristaltic) selected for a particular application should be based on properties of the liquid and the expected operating condition. One characteristic of a positive displacement pump is that when it is … Continue reading » Read the full text.

Flow Control – Centrifugal Pump
Terry Blevins
Centrifugal pumps can be used to transfer large volumes of liquid between vessels in an industrial process. When a constant speed motor is used to drive the pump then the pump flow rate may be controlled by adjusting a throttling valve that is installed after the pump discharge, as illustrated below. The pump discharge pressure … Continue reading » Read the full text.
