The pumps are designed for individual operation
in systems with higher safety requirements (P1 or P2)
Parallel operation (P1 + P2) only permitted
in constant speed mode (cs) or with external speed
setting (0 – 10 V/0 – 20 mA) but not in controlled
operation mode (cp or pp)
Optional:
– Control module (2×)
– Signal module (2×)
Both module types with integral twin pump function
22h / 2h alternating operation
See page 34 for further details
Refer to individual pump for technical data
