When pumping down dry gases, no special precautions are required. Pfeiffer Vacuum supplies the diaphragm pump ex factory for operation without control signal and with the trimmer turned to the right stop. The diaphragm pump starts directly and rotates at max. rotation speed. -
Page 23: Adjusting Rotation Speed
Operation 6.3 Adjusting rotation speed When operating the vacuum pump, there are 3 different control options, each of which can lead to a smooth circular runout of the vacuum pump at motor rotation speed > 400 rpm. The motor rotation speed of the vacuum pump increases linearly in each case up to max. rotation speed. The higher the motor rotation speed, the higher the pumping speed. -
