Submerged pumps: key facts in a nutshell
You would like to learn more about submerged pumps and need a quick overview? This page provides answers to the most important questions: What is a submerged pump? How do submerged pumps work? What purchase criteria should be taken into account before deciding for a model?
Functional principle of submerged pumps
Submerged pumps operate based on the principle of centrifugal force. The centrifugal force is the force acting to the outside in an orbital or spinning motion around a rotation axis. This principle is known from everyday life, for instance from laundry washing. During the spin cycle, the water in the washing machine is pressed to the outside and through the holes in the drum due to the fast rotation.
Submerged pumps take advantage of the same principle. First, the liquid is sucked in through an opening in the lower part of the device. A motor-driven impeller transports the liquid into the collector duct by means of centrifugal force. From there, the liquid is conveyed through a pressure outlet into the discharge hose and out of the pump.
The major advantage of submerged pumps as compared to other pumps is that they can be placed directly in the liquid. Draining operation does not require any pump lines leading to the liquid. The insulation of all live parts ensures operational safety. When used in one place only, high-quality submerged pumps can be left at the site of application permanently – there is no need to fear damage caused by wetness.
What is a submerged pump?
Pumps are referred to as submerged pumps if they are submerged in the liquid (usually water) to be pumped off or recirculated during operation. These pumps are typically electrically operated. Depending on the volume to be conveyed, the pump performance can range from 600 to 30,000 litres per hour. The fields of application of submerged pumps are extremely diverse. The pumps are used both by the fire brigade and civil protection services, but also in the area of water supply, wastewater disposal, construction work, and even aquaristics.
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.
