The pump is not to be exposed to rapid temperature changes to avoid damage through
sudden expansion/contraction of the pump components.
Pumps for handling abrasive liquids (causing wear) should be selected with care. Please
contact your local distributor for advice.
Important!
If it is proposed to modify the system/duty or to use the pump for transporting liquids
with other characteristics than for which the pump was originally selected always consult
your distributor.
2.2 Operating parameters
The maximum pressure and speed operating data are given in the table below. In
practice these performance data can be limited by the nature of the pumped media
and/or the design of the system in which the pump is installed.
2.0 Function, design, installation
2.1 Operating principle
Liquid is drawn into the pump as the rotors disengage, forming cavities. The liquid is
transported in the cavity of the rotors around the periferi of the rotor case. Liquid is
pressured out from the pump as the rotors engage, closing the cavities.
