Submerged clear water pump TWP 4006 E

Pump with near-ground suction (max. 7,300 l/h) for wipe-dry results – with an adjustable residual water level

Water pumping in the house and garden made easy

With 400 watts of power, the submerged pump TWP 4006 E moves the masses. Being a flexible helper in the home, garden and business, the universally applicable submerged clear water pump with its high flow rate is suitable for recirculating and pumping only slightly contaminated clear water (with dirt particles sized up to 5 mm) out of swimming pools, wells, rain barrels, cisterns or rainwater tanks. Similarly, the submerged pressure pump TWP 4006 E with near-ground suction can be used to dry out basements and washrooms that have been flooded due to heavy rainfall, washing machine leaks or the ingress of groundwater, leaving "wipe-dry" results and a low residual water level of only 5 mm. When used as a drainage pump in a drainage shaft, the robust pump, which is protected against the ingress of water by IPX8 type of protection, ensures that the accumulated rainwater is pumped out in a controlled manner.

Submerged clear water pumps of the TWP series at a glance

One of the most important criteria when selecting a submerged clear water pump is the pump capacity. Therefore, before purchasing, check whether the flow rate and delivery head are suitable for your application. Even larger water volumes can be transported using the structurally identical model TWP 7506 E with a maximum flow rate of 13,000 litres/hour.

Continuous operation and manual operation with preselected switch-on/switch-off height

The watertight (encapsulation) and extremely robust plastic housing of the TWP 4006 E is designed for underwater use up to 7 metres. From a water level of only 55 mm, the submerged pump starts suction. Similarly, the submerged pump can be used in manual operation with an individually preset switch-on and switch-off height. A holder on the pump housing allows the float position to be easily locked in order to individually adapt the switching heights to the application. If the otherwise freely movable float switch is fixed, the TWP 4006 E will pump continuously.

Durable, safe, good

Homeowners and passionate gardeners appreciate the quality and features of the extremely durable submerged pumps of the TWP series. The motors, which are both powerful and maintenance-free, have an integrated thermal protection circuit to gently switch off the pump technology in the unlikely event of overheating. An integrated backflow preventer keeps the hose from running dry after shutdown and thus reduces the time to restart suction.

Submerged clear water pump TWP 4006 E

One for all: flexible hose, tube and plug-in system connections

With the TWP 4006 E you have complete freedom of connection. No matter whether you want to connect the pump to a garden hose, an existing piping or irrigation system – the TWP 4006 E offers almost unlimited compatibility. The submerged pump allows the connection of hoses, tubes and plug-in systems with different diameters, with and without threaded connections. The reduction required for this is already included in the scope of delivery with various connection sizes.

Flexible all-rounder: 360° elbow with Quick-Connect connection

The convenient elbow will turn your head. With it, hose, tube or plug-in systems can be attached to the pump quickly and easily with just one movement and flexibly positioned at any angle. Simply plug it in and remove it again at the push of a button when the work is done.

Connection options of the TWP 4006 E:

  • Hose connection for an inner diameter of 25 mm or 38 mm 
  • Hose and pipe connection for internal threads G1"/DN25 or G1½"/DN40

For self-pumped water – everywhere

The carrying handle integrated in the pump housing simplifies the transport of the compact and only 4 kg light TWP 4006 E in the garden or at other locations. Additionally, it serves as a suspension for the nylon cord (10 m) included in the scope of delivery to lower the submerged pump into wells, cisterns or other basins.

Special equipment features of the TWP 4006 E

Particle size: 5 mm
The submerged clear water pump TWP 4006 E conveys clear or only slightly contaminated water with particle sizes of up to 5 millimetres.
360° adjustable elbow
The elbow's position can be freely adjusted by 360°, so that it is possible for hoses and pipes to run parallel to the ground.
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 / 38 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 5 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 5 mm remain).
Quick-Connect connection
Thanks to the Quick-Connect connection, 25/38 mm hoses (1" / 1½" thread) can be mounted quickly and easily.

The TWP 4006 E is extremely versatile

Application in flooded living rooms and basements
Your living spaces or basement have been flooded by heavy rainfall? If the water to be pumped off is only slightly contaminated, this does not constitute a problem for the clean water pump TWP 4006 E.
Application in swimming pools
The submerged clear water pump TWP 4006 E with near-ground suction pumps level ground "wipe-dry", i.e. to a residual water level of only 5 mm.
