Pump kit, submersible, 3"

A 3" diameter pump set supplied with rising main, wellhead assembly and control panel. Used for pumping from water depth 25-60m.

This pump unit and equipment has provided a dependable and easy to use option in numerous programmes over many years. The 3" unit is preferred as many of the existing boreholes across the work regions are typically small diameter 4" wells.

• rated flow 5 m³/hr at rated head 73 m
• 3" diameter pump and single phase motor
• Electrical switching device (connected in series to pump power supply from generator)
• power requirement 2.2 kW (recommended minimum 5 kVA generator)

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 Rising Main Installation kit, Oxfam Code: BSPI, is designed for raising and lowering pumps where the flexible rising main is fitted.
• This submersible pump will require a single phase power supply. Oxfam code: KG6 is suitable.
• Pump protection: This pump does not require low water level probes, as thermal/resistance protection is built in to the pump. A dip can be used to monitor water level and then operate the pump manually. Dipper tube is included but a dip meter must be ordered separately.
• The pump is supplied with a flow sleeve. A flow sleeve is used to solve problems of motor overheating and the build up of corrosive deposits. A flow sleeve is a stainless steel cylinder that surrounds the motor and pump intake. During pumping all water is drawn through the sleeve which cools the motor. The flow sleeve has an external diameter of 4" therefore it can only be used in a borehole of more than 4½" (120mm) internal diameter.
  NOTE: If the sleeve cannot be fitted then the pump should be installed above the screen casing, to draw water past the motor for cooling.
