Submerged clear water pump TWP 7505 E

750 W pump with near-ground suction for wipe-dry results with a flow rate of up to 13,000 l/h

The submerged pump TWP 7505 E impresses with its high performance and easy handling. That makes it an equally attractive purchase object for home owners needing a tool for the quick and efficient elimination of a leakage in interior spaces as it does for professional and amateur gardeners wanting to pump over irrigation water from wells, rain barrels and tanks outside. It is ideally suited for use to a delivery head of 10 metres. The maximum flow rate amounts to remarkable 13,000 l/h.

With its powerful and maintenance-free 750 W motor the clear water pump TWP 7505 E conveys clear or only slightly contaminated water with particle sizes of up to 5 millimetres. Owing to the high conveying capacity the submerged pump drains flooded basements and laundry facilities before you know it, pumps dry entire swimming pools at a remarkable speed and ensures the quick pumping over of water in cisterns and rain barrels that are full to the brim. The convenient backflow preventer keeps the hose from running dry after switch-off and so reduces the time to restart suction.

Pump it off and mop it up, that's all it takes!

The device with near-ground suction pumps level ground "wipe-dry", i.e. to a residual water level of only 3 mm. Hence, the clear water pump is ideally suited for drying shallowly flooded surfaces f.i. in basements or swimming pools quickly and thoroughly. All the TWP 7505 E needs to start the internal pump wheel is a water level of 80 mm. 

The both watertight and impact-resistant plastic housing of the pump is suitable for underwater application to a depth of 7 metres. Seeing as the submerged clear water pump comes equipped with an integrated thermal protection circuit for overheating protection it is also optimally prepared for long-term applications. A high-quality ceramic face seal and a low-wear shaft further ensure the durability of the TWP 7505 E.

Quick and easy handling

Thanks to the steplessly lockable float switch the functioning of the electric pump is conceivably easy: simply set the desired water level and the automatic switch-on/switch-off function will take care of the rest. The dry run protection offers yet more flexibility during automatic operation. Evidently, manual operation is also possible at a low water level.

Via the float switch you can control the water level in the room or container to be drained. The pump switches on and off automatically according to the height of the float switch.

Convenient handling

The comfortable carrying handle facilitates transportation of the TWP 7505 E within the garden or to any other application site. At the same time it can be used as pump suspension option using the supplied nylon cord, e.g. for lowering the pump down into a pool. The compact device is equipped with universal connections at the elbow for inner diameters of 25 mm and 32 mm as well as 1'', 1¼'' and 1½''.

If desired, further hoses can quickly and easily be connected to the pump using the existing threaded connectors. 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 a wide operating range.

Do you need maximum pump capacity or is a little less also sufficient?

Depending on your individual requirements Trotec's submerged clear water pumps TWP 4005 E and TWP 9005 E recommend themselves with a maximum delivery head of 7.5 or 11.5 metres and a flow rate of up to 7,000 or 14,000 litres per hour.

Schematic overview

The TWP 7505 E is extremely versatile:

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.
Immersion depth: 7 metres
With the submerged pump TWP 7505 E pumping off or recirculating the slightly contaminated water from cisterns or rain barrels can be accomplished in a trice.
For use in slightly contaminated water as collected in rain barrels
