SUBMERGED PUMPS

Whether clear or waste water – we always have the best solution at hand

Our submerged pumps for clear and waste water are efficient, safe-to-operate "underwater" pumps that handle even high feed rates with ease. They can be used for versatile applications including irrigation and drainage in clean as well as in heavily contaminated water. Their range of applications includes, for instance, water removal from lakes, ponds and rivers, recirculation and suction of water from a pool, pond, cistern or rain barrel, and draining of a flooded basement.

For depending on whether it is used for clear or waste water, on shallow or deep surfaces, for small or large dirt particles, we recommend choosing a pumping solution that is optimally tailored to your requirements. While clear water pumps are suitable for use in swimming pools, tanks, cisterns and wells, submerged waste water pumps convey heavily contaminated water with particle sizes of up to 25 mm. For this reason, we decided to offer both submerged clear water pumps with near-ground suction and submerged waste water pumps.


The difference between submerged clear water and submerged waste water pumps:

Submerged clear water pumps:

Submerged clear water pumps are used to effectively pump off and recirculate clear liquids or liquids that are only slightly contaminated with dirt particles, for instance to convey domestic sewage, rain or seepage water, in case of a washing machine leakage or for draining a pool. The maximum particle size indicates how large the dirt particles may be without causing damage to the pump.

A particular advantage offered by submerged clear water pumps is the possibility of "near-ground suction". Due to this technical feature, the water can be pumped off to a particularly low water level of only a few millimetres – resulting in what is called "wipe-dry drainage". The minimum suction level to which water can be pumped off is specified in the pumps' technical data.

Submerged waste water pumps:

Submerged waste water pumps convey heavily contaminated water, which is for example required when emptying garden ponds, tanks or cisterns, pumping water out of building and waste water pits, withdrawing water from lakes, ponds and rivers, or in cases of emergency draining due to flooding. Here, too, the maximum particle size indicates the maximum diameter of the contaminations contained in the pumped liquid. Naturally, submerged waste water pump are also suited for transporting clear water. 

In addition to the already mentioned typical purposes of use, the versatile range of applications of submerged waste water pumps also includes drainage under difficult and extreme conditions. Due to their high-quality technology, the pumps are an indispensable aid for emptying building and waste water pits as well as for emergency draining in case of flooding.

Clear water may only contain dirt particles up to a diameter of 5 mm. For a wipe-dry result, Trotec's submerged clear water pump with near-ground suction is able to pump water off to a residual water level of 3 mm when placed on level ground.

Waste water may contain small stones, pieces of wood or clods of soil with a diameter of up to 25 mm. Trotec's high-performance submerged waste water pumps pump the water off to a residual water level of 35 mm.
