Function of the product
Variable speed control (Fig. 8)
The pump's speed is switched in three stages using a rotary
knob. The speed in the smallest stage is approx. 40 to 50 % of
the maximum speed with a reduction of the current consump-
tion to 50 %.
Special pump features
For a double pump, the two motor impeller units are fitted iden-
tically and are mounted in a common pump housing with inte-
grated switchover valve.
Each pump can run individually, but both pumps can also run at
the same time in parallel operation. The operating modes are
main/standby or parallel/peak-load operation. The individual
units can be configured for different capacities. With the dou-
ble pump, a system can be adapted to individual operating sit-
uations. It is necessary to connect a corresponding switchgear
for switching-over in order to control the different operating
modes.
