Series MV-345 Vertical Multistage Pump, 45 m³/h
VQ-MV345
Vertical multistage pump, flow 12 to 58 m³/h, head 18 to 190 m.
- FLOW
- 12 to 58 m³/h
- HEAD
- 18 to 190 m
- PRESSURE
- PN40
- STAGES
- 1 to 13
Why it is specified
Pressure without a big footprint: the stages stack vertically, so a fifteen-bar duty occupies the floor area of a bar stool. Specified for boosting, washing and reverse osmosis feed, where the head matters more than the flow.
Typical applications
- Boiler feed
- Industrial water treatment
- Pressure boosting
- Reverse osmosis feed
- Washing and spray systems
Options and executions
- 1.4404 execution for chloride-bearing water
- Dry-run protection
- Pressure vessel and manifold kit
- Stainless base and clamps
- Variable speed drive with pressure set point
