Davey 23A/B High Pressure Submersible Drainage Pump 240V
SKU: D23AB
The D23a/b models are able to pump clean water of neutral pH ( ie rainwater )
Designed for pumping clean rainwater and activated by an automatic float.
The range of submersible High Pressure Drainage pumps are specialty pumps that are designed with superior reliability in mind for rainwater tanks, and suitable for pumping drinking water with a neutral pH.
Using an automatic float, it detects when water is available. Primarily used with rainwater tanks, it’s also used for lawn and garden irrigation, treated effluent disposal and water transfer from wells.

Priming & Operation
- Use a rope to position and retrieve the pump. Do not lower or retrieve the pump using the power lead as this may damage the cable entry seals, causing water leaks and unsafe operation.
- Don’t use this product for recirculating or filtering swimming pools, spas, etc.
- While these pumps are built to high safety standards, they are not approved for installations where people will be in the water while they are operating.
- Don’t pump abrasive materials. Sand and grit in the water being pumped will accelerate wear, causing shortened pump life.
- Keep your pump clean, particularly in situations where lint, hair or fibrous materials may get bound around the pump shaft. Inspection every 6 months and cleaning will extend pump life.
- Make room for the float switch to operate. Automatic models have a float switch to turn them on when the water level rises and turn them off again when it has been pumped down to the safe operating level of the pump. If the float switch is not free to rise and fall, correct pump operation may not be possible.
