2.2 Operating
conditions
The FKV and FKC pumps are suitable for the following operating situations:
S1 operation
(continuous operation), the pump must always be covered by the pumped liquid to the top
of the motor. See fig. 2.
S3 operation
(intermittent duty), the pump must always be covered by the pumped liquid up to the top
of the pump body. See fig. 2 (only for non explosion-proof versions).

Stop levels
pH value
FKV and FKC pumps in a fixed installation can be used for pumping liquids with pH values from 6.5 to 12.
Temperature of the operating liquid
0 °C to +40 °C.
For short periods a temperature of up to +60 °C is permissible (non-Ex versions only).
Explosion-proof pumps must never pump liquids of a temperature higher than +40 °C.
Ambient temperature
For non-explosion proof pumps, the ambient temperature may 40 °C for a short period.
For explosion-proof pumps, the ambient temperature on the installation site must be in the
range from -20 °C to +40 °C.
Density and viscosity of pumped liquid
When pumping liquids with a density and/or a kinematic viscosity higher than that of water, use motors with
correspondingly higher outputs.
