Submerged waste water pump TWP 4025 E

Powerful suction plus effectiveness – the ideal solution for house and garden

Impressive 400 watts of power for pumping up to 7,500 litres per hour

Contaminated water in the house, garden or well should be pumped off as quickly and as effectively as possible – the thoroughly robust and powerful submerged waste water pump TWP 4025 E is perfectly suited for this purpose. It meets every challenge and transports water containing dirt particles sized up to 25 millimetres.

The submerged waste water pump TWP 4025 E reliably transports up to 7,500 litres of contaminated water per hour up to a pump height of 5 metres with a power consumption of 400 W. Flooded basements and living spaces are quickly rendered accessible again, and building or waste water pits can be emptied just as effectively as ponds, tanks or cisterns. Thanks to the pump's high conveying capacity, water can be quickly and easily withdrawn from lakes, ponds or rivers for lawn sprinklers or complex irrigation systems. Naturally, the submerged pump TWP 4025 E is also suited for transporting clear water.

Robust and durable quality

The TWP 4025 E is also perfectly equipped for long-term applications, for the device comes with both a maintenance-free motor and an integrated thermal protection circuit. Furthermore, the high-quality ceramic face seal and a low-wear shaft ensure extreme durability.

The watertight (encapsulation) and impact-resistant plastic housing of the TWP 4025 E is suitable for underwater application to an immersion depth of 5 metres. The robust pump can be put into operation as of a water level of only 90 mm. Once switched on, the device pumps off the waste water until reaching a residual water level of 35 mm.

With a pump height of up to 5 metres, the pump is able to transport water from a flooded basement to the next higher floor and thus out of the house.

The TWP 4025 E combines functional variety with easy handling

The steplessly lockable float switch of the TWP 4025 E offers the option to choose between automatic and manual continuous operation. If, however, the float switch is locked horizontally in the position for permanent operation, the device will operate in continuous mode.

With universal connections for inner diameters of 25 mm and 32 mm as well as with threaded connectors of 1'' and 1½'' further hose and also pipe connections can be established conveniently. The elbow's position can be set to various positions as desired so that it is possible for hoses and pipes to run parallel to the ground. The stable, ergonomic carrying handle additionally facilitates the handling of the compact submerged waste water pump and can also be used for suspending the device at the supplied nylon cord. Thanks to a 10 metre connecting cable the pump can be quickly installed, and using the suspension cord the pump can be easily lowered into the water and raised again when required.
