Learn about fluid viscosity and its effects on positive displacement pumps. Pressure changes, pump capacity, cavitation and more.
DPP Magnetically coupled gear pumps avoid the life-limiting seal by using a magnetic coupling to transfer torque into the pump. This establishes a hermetic seal while still coupling the motor to the driving gear.
An abrasive fluid is one that causes increased wear to the fluidic system by eroding surfaces through physical interaction. Erosion can occur from simple flow across a surface or by the abrasive particles interfering with internal component interactions within a pump.
All pumps operate by creating a low pressure at the inlet and allowing atmospheric (or system) pressure to push fluid into the pump. The process makes all pumps susceptible to a phenomenon called cavitation.
