Gear pumps operate by creating low-pressure zones at the suction port (see diagram), allowing atmospheric pressure combined with the static head of liquid above the pump centerline to force liquid into the pump.
To understand how gear pumps work, the [...]
Gear pump users often blame the pump itself for problems in transfer, metering, and pressurization systems
With more than 25 years of experience solving viscous-fluid handling challenges across a wide range of industrial processes, we can say it's rare for the pump [...]
Positive displacement (PD) pump flow is virtually unaffected by differential pressure it's continuous and pulsation-free. PD pumps have very tight internal clearances, which minimizes the amount of liquid that recirculates within the pump (known as slip). For this reason, positive displacement pumps are [...]
The pump won't draw viscous product. This indicates something is preventing product from reaching the pump. Common causes of head loss include: excessive distance between the tank and the pump, undersized suction piping, or too many reducers, valves, elbows, and other restrictions in the [...]
