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 radical 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 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.
III. Deceleration: With Eckerle internal gear pumps very high decelerations can be achieved, it must be ensured though that line-dependent pressure peaks can develop within the suction side. These should not exceed the maximum permissible inlet pressure.
IV. Pressure Holding Operation: Eckerle internal gear pumps are able to build up high pressures even at very low speed due to the gap compensation, hold pressure operation is thus extremely energy-efficient. Pump operation should follow after the hold pressure operation to flush out the pump.
V. Reverse Operation: Eckerle internal gear pumps are usually able to run highly dynamically in the oppsite direction of rotation in order to lower pressure peaks, or by means of a hydraulic motor. However, it must be ensured that the output pressure is always higher than the input pressure.
VI. Acceleration: With Eckerle internal gear pumps very large speed-ups can be run. These are limited by inlet pressure, geometry of the suction line and viscosity. However, these may not drop below the specified minimum inlet pressure of the series.
* To avoid critical operating points, we recommend taking measurements of the pump’s inlet and outlet pressure near the pump with a scanning rate of at least 1 kHz when a new pump cycle starts.
