Submerged waste water pump TWP 11025 E

Powerful 1,100 W pump with a flow rate of up to 15,000 l/h

TWP 11025 E – Trotec's powerful submerged waste water pump accomplishes virtually any task with flying colours.   Making use of 1,100 watts the pump reliably pumps up to 15,000 litres per hour of clean or contaminated water containing dirt particles sized up to 25 millimetres from a delivery head of up to 11 metres. Hence, it is equally suitable for use in garden ponds, drainage shafts or cisterns as it is for the quick draining of rooms affected by a flood or heavy rainfall. Withdrawing water from lakes, rivers and swimming pools can achieved without difficulty.

A water level of 7 metres is reduced to merely 35 mm before you know it

The robust and compact submerged pump is accommodated in a watertight encapsulated and impact-resistant plastic housing and therefore optimally prepared for underwater application at an immersion depth of up to 7 metres. Starting at a minimum depth of 115 mm the pump operates at a high efficiency level and reliably siphons off waste water to a height of 35 mm.

The TWP 11025 E can not only be used for water withdrawal so as to operate an irrigation system, for water removal after flooding as well as other fields of application involving contaminated water, but is naturally also suitable for transporting clear water. Long-term applications can be realized without difficulty. For the pump comes with both a maintenance-free motor and an integrated thermal protection circuit. The high-quality ceramic face seal and low-wear shaft additionally ensure the extreme durability of this high-performance pump.

Easy to handle – in automatic or manual operation

Starting and residual water level

Via the steplessly lockable float switch the TWP 11025 E can be set to either automatic or manual continuous operation. In automatic mode, the previously defined water level ensures the switch-on/-off of the device. Due to the dry run protection the pump operation will automatically be switched off upon reaching an insufficient water level. If, however, the float switch is locked horizontally in the position for permanent operation, the device will operate in manual continuous mode.

The elbow position can be flexibly adjusted, as a result it is possible for hoses and pipes to run parallel to the ground. The powerful submerged waste water pump is equipped with universal connections for inner diameters of 25 mm and 32 mm as well as threaded connectors of 1'', 1¼'' and 1½''. A stable carrying handle facilitates site changes and simultaneously serves as suspension for the nylon cord included in the scope of delivery. With it the pump can easily be lowered even to great depths and pulled back up as needed. The connection cable of 10 metres length facilitates the flexible application of the pump.

A suitable pump for any requirement

The submerged waste water pumps TWP 4025 E and TWP 7025 E are our recommendation for smaller delivery heads of up to 5 or 9 metres. They can achieve flow rates of up to 7,500 or 13,000 litres per hour.
