Submerged clear water pump TWP 4005 E, near-ground suction

Wipe-dry with a minimal residual water level due to near-ground suction

Impressive 400 watts of power for pumping up to 7,000 litres per hour

The compact submerged clear water pump TWP 4005 E wows homeowners and passionate amateur gardeners alike with its high capacity and the user-friendly handling characteristics. The maximum feed rate of 7,000 litres per hour recommends the TWP 4005 E as much as the extraordinary pump height of 7.5 metres. An integrated check valve prevents the return flow upon switch-off. 

With its powerful and maintenance-free 400 W motor the submerged clear water pump TWP 4005 E conveys clear or only slightly contaminated water with particle sizes of up to 5 millimetres. The submerged pump drains flooded basements and laundry facilities at a remarkable speed. It can be used to empty swimming pools in a trice and further leaves a good impression when pumping over the water in cisterns and rain barrels that are full to the brim. An integrated backflow preventer keeps the hose from running dry after shutdown and so reduces the time to restart suction.

A residual water level of no more than 3 mm – simply mop it up and you're done!

Moreover, the clear water pump is ideally suited for drying shallowly flooded surfaces f.i. in basements or swimming pools quickly and thoroughly. For the near-ground suction of the TWP 4005 E needs a water level of no more than 80 mm to start the internal pump wheel. Then the device pumps level ground "wipe-dry", i.e. to a residual water level of only 3 mm.

The watertight (encapsulation) and impact-resistant plastic housing of the device is suitable for underwater application to an immersion depth of 7 metres. With the integrated thermal protection circuit activated by overheating of the device the pump is also perfectly equipped for time-consuming applications. The high-quality ceramic face seal and a low-wear shaft further ensure extreme durability.

Easy-to-handle TWP 4005 E – compelling

Thanks to the steplessly lockable float switch it is conceivably easy to operate the TWP 4005 E. The device will be switched on and off automatically depending on the specified height of the water level. Manual operation is also possible with a low water level by locking the float switch horizontally in the position for continuous operation.

The practical integrated float switch controls the water level in the container to be drained. When set to automatic operation, the pump switches on and off automatically according to the height of the float switch. In continuous operation the pump permits near-ground suction to a residual water level of 3 mm.

The sturdy ergonomic carrying handle facilitates easy transporting in the garden or to any other application site and optimizes the handling of this compact device. It can further be used as pump suspension option using the supplied nylon cord, e.g. for lowering the pump down into a swimming pool. With universal connections at the elbow for inner diameters of 25 mm and 32 mm as well as with threaded connectors of 1'' and 1½'' further hose connections can be established without further ado. The elbow's position can be freely adjusted, as a result it is possible for hoses and pipes to run parallel to the ground. The power cable of 10 m length offers flexibility and a wide operating range.

Special equipment features of the TWP 4005 E

Particle size: 5 mm
The submerged clear water pump TWP 4005 E conveys clear or only slightly contaminated water with particle sizes of up to 5 millimetres.
Ceramic face seal
The high-quality ceramic face seal and a low-wear shaft extend the pump’s lifetime.
Integrated backflow preventer
The integrated backflow preventer (non-return valve) prevents the return flow of the water at the end of the pumping process.
Universal connections
Hoses and pipes with an inner diameter of 25 / 32 mm as well as 1‘‘ / 1½‘‘ threaded connectors can be flexibly coupled with the pump.
Steplessly adjustable float switch
The height for the pump’s automatic switch-on/-off can be reliably regulated by means of the steplessly adjustable float switch.
Near-ground suction during continuous operation to a residual water level of 3 mm
When locking the float switch in horizontal position, the pump operates continually and sucks off the water until the ground is “wipe-dry” (only 3 mm remain).
Ergonomic carrying handle
For lowering the pump into the water, the supplied 12 m nylon cord is affixed to the sturdy, ergonomic carrying handle.

The TWP 4005 E is extremely versatile

Suitable to an immersion depth of 7 metres
Up to an immersion depth of 7 metres, the pump is ideally suited for all applications in clear or only slightly contaminated and chlorinated water.
For use in slightly contaminated water as collected in rain barrels
With the submerged pump TWP 4005 E pumping off or recirculating the slightly contaminated water from cisterns or rain barrels can be accomplished in a trice.
Draining in the staircase to the basement
The basement steps have been flooded owing to heavy rain? If the water to be pumped off is only slightly contaminated, this does not constitute a problem for the clean water pump TWP 4005 E.
Application in swimming pools
Used in swimming pools or laundry rooms – the submerged clear water pump TWP 4005 E with near-ground suction pumps level ground “wipe-dry”, i.e. to a residual water level of only 3 mm.
