WPS - Solar Borehole Pumps

A WPS® Solar borehole pumping system is composed of three main elements: a WPS® borehole pump, a WPS® submersible motor and a WPS® Solar controller.

WPS® borehole pumps:

• Any of the WPS® borehole pumps can be used in a WPS® Solar pumping system, from the 3” WPS to the 10” WPS.
• Every WPS® borehole pumps is made out of high quality stainless steel, used for its impellers and diffusers
• Flow from 0.5m³/h up to 260m³/h
• Head up to 650m

WPS® submersible motors:

• 3” WPS® AC motors from 0.6kW up to 1.5kW, 3x230V, 140Hz used for all systems using a 3” WPS® borehole pump (Except for the 3” WPS® Solar PMM pumping packs)
• From 0.25kW up to 1.5kW, the motor used are 3x230V, 50Hz, DOL
• From 2.2kW up to 185kW, the motor used are 3x400V, 50Hz, DOL

WPS® Solar controllers:

• Integrates a frequency driver electronically controlled to enable WPS® submersible motors to work on power coming directly from the solar panels
• General On-Off switch
• MPPT (Maximum Power Point Tracking) system, ensuring that the motor is always working at the maximum power regarding the solar power available
• Dry running protection
• DC breaker
• Motor overload and underload protection
• LED indicators
• IP54 enclosure
• Two auxiliary contacts for external switches
