Pump kit, solar, submersible, 3", low yield

A 3" (74 mm) diameter, 'Low Yield' pump set supplied with rising main, well head assembly and control panel. The pump package also includes PV array and has switching control to enable it to be powered by an AC generator (Note: Generator must have Automatic Voltage Regulator - AVR, fitted).

This 'low yield' kit is offered as a simple installation for a community water supply, school, health post or staff compound. The 3" pump is preferred to enable the unit to be used in existing boreholes that commonly have 4" casing.

• The kit is selected to be capable of delivering approximately =/>10 m³/day at 10-30 m total head, based on general solar irradiation figures between 20° North and South of the Equator.
• This submersible pump kit is designed to be powered using the Solar Panel kit included.
• The control panel also permits switching to a single phase 220-240 VAC supply.
• Pump protection: This pump control panel has integrated dry running protection for the pump and the kit includes a water tank level float switch to control pumping.

User notes

• Damage can be done to submersible pumping equipment and to the borehole if the system is not selected correctly and pumping is not carefully controlled and managed. A full borehole draw-down test is an essential part of pump selection and system operation.
• The following information should be considered before ordering:
  a) Available solar irradiation at the location
  b) Daily water requirement
  c) Borehole performance & recharge
  d) Total pumping head to storage
  e) System water storage requirement, to cover morning and evening demand when pumping is lowest.
