Submerged waste water pump TWP 4036 E

High-performance pump (max. 7,500 l/h) for pumping out waste water indoors and outdoors – with an adjustable residual water level

Powerful all-rounder for pumping water in the house, garden and business

Summer, sun and sunshine? After days of heat, the warmest time of the year is increasingly showing its dark side. Lawns in the garden burn and plants die of thirst if they are not watered with vast quantities of water. Blessed is the one who has a TWP 4036 E submerged waste water pump and can pump free service water from the garden pond or a cistern. But not only gardens are the ideal working environment for the powerful submerged pump. It is not uncommon for continuous rain and storms to lead to flooded streets, flooded garages and a rising water level in the basement. With the robust pump TWP 4036 E, which is protected against the ingress of water by IPX8 type of protection, you can also remove these dirty water masses (with dirt particles sized up to 25 mm) in the shortest possible time.

Rises to every challenge and water quantity

Soiled water masses in the basement or garage are pumped out by the powerful 400 W TWP 4036 E just as powerfully and quickly as rainwater from overflowing building pits or free service water from ponds, wells and streams for watering the garden.

Submerged waste water pumps of the TWP series at a glance

One of the most important criteria when selecting a submerged waste 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 per hour can be handled using the structurally identical model TWP 7536 E as well as the submerged pumps TWP 9000 ES and TWP 11000 ES made of high-quality stainless steel.

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

The watertight (encapsulation) and impact-resistant plastic housing of the submerged pump is designed for underwater application to an immersion depth of 7 metres. From a water level of 85 mm, the submerged pump starts pumping until the residual water level of max. 40 mm is reached. In addition, the submerged pump can be used in manual operation with an individually preset switch-on and switch-off height. A float switch lock on the pump housing allows individual adjustment of the pumping height within a defined range. If the otherwise freely movable float switch is fixed, the TWP 4036 E will pump water continuously.

Universal connection for hoses, pipes and plug-in systems

With the submerged waste water pump TWP 4036 E you can go for "all in one" instead of "either or" when it comes to choosing the connection options. No matter whether you want to connect the pump to a garden hose, an existing piping or irrigation system – the TWP 4036 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 4036 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 and drainage work – everywhere

With the carrying handle integrated in the pump housing, the pleasantly compact and only 4 kg light TWP 4036 E offers extreme mobility in the garden or at other locations. Additionally, the handle 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.

Tested for safety for long-lasting use

The submerged pumps of the TWP series are robust and durable pumps designed for continuous operation in harsh environments. 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.
