Series CP-120 Close-Coupled Centrifugal Pump
VQ-CP120
Close-coupled centrifugal pump, flow 2 to 48 m³/h, head 8 to 42 m.
- FLOW
- 2 to 48 m³/h
- HEAD
- 8 to 42 m
- PRESSURE
- PN16
- TEMPERATURE
- -20 to +110 °C
Why it is specified
The close-coupled build puts the impeller on the motor shaft, so there is no baseplate, no coupling and no alignment to lose. It is the shortest pump on the shelf for a given duty, and the one that fits in the plant room that was designed without one.
Typical applications
- Boiler feed, low pressure
- Clean-in-place supply
- Cooling water circulation
- Pressure boosting
- Process water transfer
Options and executions
- ATEX zone 2 execution
- Double mechanical seal
- Flushing plan 11 or 21
- Frequency converter, motor mounted
- Performance test to ISO 9906 grade 3
