Solar Pump
Horizontal end-suction pump series, supplied with a HOBER solar pump inverter for surface water pumping on solar DC with grid AC as the alternative.
Ranges are based on the positive-flow catalogue points of the models shown: the point at zero flow is the shut-off point of the curve, not a duty point. More NIS models are available on inquiry. Read flow and head together on the curve for the model selected.

06 / Questions
Please provide the required flow rate and total dynamic head, water source and liquid conditions, suction arrangement, operating hours and available power supply. Selection is checked against the exact model curve, motor specification and site conditions.
No. NIS is a non-self-priming end-suction centrifugal pump. The priming method and suction conditions must be checked for the installation before operation.
NIS pumps can be considered for clean-water river intake, irrigation and transfer projects. Suitability depends on water quality, intake screening and the suction arrangement. Tell us about sediment or debris so that the pump and intake can be reviewed for the application.
No. Maximum flow and maximum head are separate limits. The required flow and head must be checked together on the exact model performance curve.
The PV array supplies DC power to a solar pump inverter, which drives the pump motor and adjusts its operating frequency as available solar power changes. The motor and PV array must be matched to the selected inverter.
Provide the minimum water level relative to the pump, suction-pipe length and diameter, fittings, liquid temperature and site altitude. These conditions are used to assess suction losses and the available NPSH against the selected pump's requirements.
Download the 50 Hz technical catalogue for performance curves, tables, sectional drawings and dimensions. Confirm the exact model and selected configuration before finalising pipework or foundations.
