CALPEDA 4SM 18 submersible borehole pump kit 4" with variable speed drives - 230V 2 m3/h

The variable speed drives start-up the pump when taps are open, and it stop the pump when the tap are off. The flow is variable depending usage, but the pressure stay constant. Esay setting of variable speed (drop-down menu), View of status on LCD screen. The variable speed protect the pump against : dry-running, over current, and under or over voltage.

Usage :
- from 1 to 2 m3/h with total discharge heighter until 136 m.
- for clean liquid, quantity of sand in water to 100 g per pumped m3.
- temperature of pumped liquid from 0 °C to + 35 °C.
- start-up per hour : maximum 20 at regular intervals.

Installation :
- in 4" cased wellbore.
- in tank, cisterne (horizontal position in cooling jacket). To see accessoires in submersible pump range.

Advantage :
- complete kit, ready to use.
- don't need big tank (8L).
- work without electric control unit and dry-running protection.
- only one setting  = designated pressure.
- the constant pressure enable an high flexible operating.
- no water hammer possible.
- efficiency of engine enable saving energy.
- high life pump.
