Pump kit, Submersible, 3"

Product Code: BSQ5
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.

NOTE: 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.

User Notes
  • The steel safety cable is for use when the pump is to be mounted on existing steel rising pipes, when the pump is used in a large diameter well, reservoir or open water. Do not use the cable when installing the flexible rising main in a borehole.
  • The Pro-quip Boreline installation kit is designed for raising and lowering pumps where the flexible rising main is fitted. The pump is lowered and raised using the rising main.
  • Flow metre installation: Manufacturers recommend that a straight length of tube (5-10 times the diameter of the tube) is used before and after the meter, to ensure laminar flow through the meter. Field experience has shown that adequate and consistent accuracy can be obtained when using a 300mm straight length before the meter, this is supplied with the kit.
  • This submersible pump will require a single phase power supply. Generator, 6kVA (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. The dip meter and tubes can be used to monitor water level and then operate the pump manually.
    When used against low total heads (<30m), back-pressure should be introduced by installation and partial closure of an additional gate valve at the well head (once correctly set the valve wheel should be removed).
  • 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.

Multi-stage submersible pump fitted with electric motor.

  • rated flow 5m³/hr at rated head 73m
  • 3" diameter pump and  single phase motor
  • Electrical protection/switching device (connected in series to pump power supply from generator)
  • power requirement 2.2kW (approx 4kW for starting)
