General information

Lever-operated lift pump for a depth setting of up to 60 metres in a borehole, 4″ to 6″ in diameter with a 50mm cylinder.

Meets VLOM (village level operated maintenance) requirements.

A larger pump cylinder, 63.5mm in ID, is available; it can deliver higher capacity at shallower settings. Optional cylinder requires 65mm riser main.

A large-diameter suction tube reduces the sand intake into the cylinder.

Pump performance (based on 50-full-strokes/minute):

  1. -      50mm cylinder, depth setting at 45m: capacity 0.222 litre/stroke, output 800 litres/hour
  2. -      63.5mm cylinder, depth setting at 30m: capacity 0.375 litre/stroke, output 1125 litres/hour

Manual installation possible; special lifting equipment may be required for depths of over 30m.

Stainless steel pump rods and riser are required for water with a pH>6.5 or an iron content>1 ppm.
