Davey D42A/B High Pressure Drainage Pump
The D42a/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 D42 models can be converted to automatic water pressure systems by adding a TT45/S ‘Plug & Play Torrium 2.
Application:
Ideal for non-potable rainwater applications, lawn and garden irrigation, sump emptying to higher heads, treated effluent disposal and water transfer from wells.

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
- HO7RNF oil resistant leads , 10 meters long with 3 pin power plug for longer life in dirty water and easy connection to the mains power supply
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.
