Pump kit, Surface Water, 4" - Diesel Engine

Product Code: P4
A reliable and robust diesel powered pump set with 4" suction and delivery connections. Capable of delivering up to 12 l/s at 40m head or 35 l/s at 20m head. Kit includes hoses, all fittings for initial set-up and operation of the pump and service spare parts for the first year of operation. Used for pumping from source to storage or for distribution.

User notes
  • The 5 litres of oil supplied in this kit should be used for running-in the engine and discarded after 100 running hours and replaced with SAE 15W/40 lubricating oil (or equivalent) as in the Oil, for Pumps kit.
  • For optimum performance, the pump design is based on using 4" suction pipe work although a reducer is included to enable connection with 3" suction pipe work. Reduction in size in the suction pipe work will result in a significant drop in pump performance.
  • The fittings included are sufficient for most uses illustrated in the Surface Water Pumping Manual. The Pump Fittings kit (Oxfam code: PF), should be ordered to enable two pumps to be installed in series or parallel.
  • A gate valve is included to allow optional throttling at outlet. It can also act as an isolation valve. Pumping against a fully closed valve must be avoided and the valve must always be open during priming.
  • It is recommended that, when pumping long distances or to higher elevations, the non-return valve included is fitted to the delivery side of the pump to reduce risk of surge damage.
  • This self-priming pump has a built in non-return valve to aid priming. A low-friction foot valve (included in the kit) will also make priming easier, but will reduce the dynamic suction head. Where conditions permit, such as pumping water from a tank, the foot valve can be excluded from the pumping configuration.
Local purchase

It may be possible to purchase suitable alternative pumps in many countries. Factors to be considered include: quality/durability of equipment, reliability, performance characteristics, full specification of kit – ensure comparisons are like-for-like, compatibility with other equipment (including that of other agencies), spare parts availability.
  • Pump:
    Single stage centrifugal self-priming pump with 4" BSP(M) suction and 4" BSP(M) delivery connections.
    Cast iron construction with a mechanical carbon/ceramic seal, separate steel pump shaft, renewable cast wear plate/volute, integral non-return valve, prime and drain points.
  • Engine:
    Two cylinder air-cooled diesel engine with handle start, oil bath air cleaner with cyclonic pre-filter, renewable element oil and fuel filters, 14.5 litre (4.5 hour) fuel tank, throttle control, oil drain tap, fuel filter/water separator (agglomerator), and exhaust silencer.

Pump and engine are close coupled together and mounted on a common fabricated steel baseplate. Drilled for 4 x M10 holding down bolts.

  • Hoses
4" suction max working pressure 3 bar  burst 9 bar 
3" discharge max working pressure 10 bar  burst 30 bar
