Davey D53A/B High Pressure Drainage Pump
SKU: D53AB
The D53A/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 D53A/B model offers extra pressure for pumping up to a second story
The D53 A/B models can be converted to automatic water pressure systems by adding a TT45/S ‘Plug & Play Torrium 2.
Features and Benefits
- Float Switch fitted for automatic operation
- Double mechanical seal, one in the oil bath on the motor and an extra mechanical seal on pump for superior reliability and a long service life.
- Corrosion resistant 304 stainless steel shaft, motor shell and fasteners for longer service life
- Centrifugal multi stage 3 impeller design for low flow applications
- In built automatic thermal overload to protect the motor in the event of blockage or voltage supply problems

Installation and Priming
- 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.
- Do not 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.
- Do not 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. Regular inspection 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.
- Do not run your pump dry. Non-automatic models must be switched off manually or by way of an external float/level switch when the water level is reduced to the top of the pump housing.
