Hirschman® Rotarus® TKF Piston Pump Heads

Pumping of the medium is enabled through the lifting motion of the piston stroke at an oblique angle to the drive axis. The stroke volume is set by changing the angle of the pump head. The simultaneous rotary motion of the piston triggers the switchover from suctioning to ejection. Exactly the same volume is conveyed by the piston stroke during each rotation, achieving the same high degree of dispensing precision possible with a piston pump. The desired flow rate is thus achieved in combination with the speed.

The pump head is available with pistons in a variety of materials. As itemized in the adjacent material index, a variety of models ranging from ceramic to stainless steel is available, depending on the application and medium to be dispensed. This pump head connection technology was developed for rapid handling. Changing of heads is realized quickly and simply in a single action without using tools. Ease of cleaning is also guaranteed, thanks to the modular design of the piston pump heads.
