* All values refer to the theoretical volume flow. The actual volume flow is lower; it depends on the
operating conditions in each case.
** Valid only for short operation times. For continuous operation, please contact our service department
.
The service life of the lobes is reduced by high temperatures, especially in combination with high
pressure. Observe the material-specific differential pressure limits Notice.
*** Theoretical operating torque with max. differential pressure and water, designed for NBR elastomers.
Speed reduction for highly viscous media
When using the pump for a highly viscous medium, the pump speed must be reduced according to the
material's viscosity, to prevent the intake flow from breaking off on the suction side (cavitation protection).
Material-specific differential pressure limits
With some materials, premature wear is likely if the pump pressure is too high. Observe the following
material-specific differential pressure limits.
FPM lobes: max. 6 bar
Steel or stainless steel lobes: Please consult our service department
Cartridge mechanical seal made of Duronit: max. 10 bar
Maximum free passage: Ø 40 mm
