PUMP SPECIFICATIONS

DAYLIFF DC80D DC Engine Pumps fig 1DAYLIFF
DC80D DC Engine Pumps fig 2

The DAYLIFF DC range of self-priming engines pumps is of fully portable design suitable for irrigation, dewatering and general pumping duties. All pump bodies and impellers are manufactured from high-grade cast aluminum. Also included are quick-couple hose connectors and suction strainers. Maximum suction is 8m at sea level, though this will be reduced at altitudes.
DC
All models feature open impellers suitable for pumping lightly silted water and a sturdy carrying and protection frame. ECONO models use different specification components and are recommended for light duties and shorter operating periods.
DCX
High specification high-pressure pump with the option of single or twin impeller.
DCT
Robust diesel pumps for pumping polluted water and sewage.
DCI
Cast iron engine pumps for heavy-duty dewatering.

Note that performance curves for all engines relate to the engine governor set at a maximum speed of 3600rpm to achieve maximum rated power output. To prolong engine life pumps should only be run under maximum power conditions for short periods and for extended duty the throttle setting should be reduced to approximately three-quarters power. Pump performance will then be reduced accordingly.

SAFETY WARNINGS

SUCTION HOSE CONNECTIONS

Airtight connection of the suction hose is essential or suction prime will be lost and the pump won’t operate.

  • Ensure the suction hose is of the rigid type and it should be of the same diameter as the pump inlet and fitted with the correct connectors.
  • Connect suction hose to the pump as indicated.

PUMP OPERATION

  • CHECK ENGINE OIL. Operating without oil will cause severe engine damage and invalidate the warranty.
  • Fill the pump chamber to overflow with water through the priming port. Insufficient water will cause pump damage and limit suction performance.
  • Check that the suction hose strainer is immersed in water and above the water source bed to avoid sucking mud, silt or sand. The foot valve must be set not less than 300mm below the water surface.
  • Ensure the delivery hose is unimpeded and laid without obstruction or kinks to the delivery point .
  • Start the engine by pulling the starter cord. Ensure ignition switch ‘on’, fuel valve ‘on’ and throttle at max speed. Close fuel valve whenever pump is not operating.
  • The suction lift should be minimized to obtain maximum pump performance. The maximum suction lift is 8m at sea level, though for acceptable pump performance it should be limited below 4m.
  • Ensure the delivery head is within the performance capacity of the pump (see pump curve).

ROUTINE MAINTENANCE

For Diesel pumps see separate engine manual. The below instructions apply to petrol versions only.

ENGINE OIL
Check engine oil daily. If low refill with SAE30.
Change engine oil after first month or after 20hrs operation and thereafter every 3 months or 50 hours of operation, in both cases whichever is sooner.

AIR CLEANER
Check the air cleaner every 3 months or after 50 hours operations, whichever is sooner. Clean by blowing away accumulated dust and soaking in kerosene.

SPARK PLUG
A correctly set spark plug in good condition is essential for efficient engine operation. Check the plug every 3 months or after 50 hours operation, clean with a wire brush and set the electrode gap to 0.7-0.8mm. If general conduction is unsatisfactory it should be changed with a NGK (BPR5ES) or similar.

PUMP HOUSING
Drain water from pump housing after use by releasing the drain plug.
