Muliple pumps type G2, series 4X

Pump I Pump II

Technical data (for applications outside these parameters, please consult us)

– The same general parameters apply as with single pumps Weight: See table of individual pump types
(see page 3) Combination parts: plus 0.4 kg

Please note with multiple pumps the following is of


particular importance:
– Nominal size 4 cannot be used as pump 1.
– Pump I should have a higher load than pump II (pressure x
flow).
– The individual pumps are separated on the suction side by a
shaft seal ring (pumps can draw from different tanks).
– The drive shafts and the coupling piece between the pumps
have limitations with regard to the transferable torque
(see below).
– When selecting the multiple pumps it must be ensured that the
sum of the torques does not exceed the permissible values.
