Variable-speed operation As a matter of principle, Eckerle internal gear pumps are eminently suited for variable speed operation. Even at low viscosities and high temperatures of the pumping medium, the pumps run extremely energy efficiently and highly dynamically over a wide speed range due to the radial and axial gap compensation. However, with variable speed operation certain boundary conditions should be observed. The exemplary cycle shown below illustrates this clearly.

I. Start: Eckerle internal gear pumps are able to build up pressure from standstill. This happens smoothly when the pump starts from an unpressurized state. Please talk to Eckerle, if due to the system design the pump is pressurized at standstill. II. Pump operation: Eckerle internal gear pumps are capable of providing a speed-dependent volumetric flow at any pressure level during pump operation. However, application limits of the respective sizes must be observed. 2) III. Deceleration: With Eckerle internal gear pumps very high decelerations can be achieved. It must be ensured though that line-dependent...
