Drainage/Sewage Pumps

WASTE AND CLEAN WATER SUBMERSIBLE PUMPS

Waste water pump

Waste water pumps transport heavily contaminated water which often contains solid particles of various organic, inorganic and mineral origin. Waste water pumps are generally not self-priming and are completely submerged in the fluid handled. Wear-resistant mechanical seals are used as a shaft seal. Read More

Typical applications are those of the food processing, construction, pulp and paper, sugar, and metal industries (e. g. metal electrolysis) as well as mining and water extraction (e. g. cooling water, seawater desalination). A distinction is made between municipal and industrial waste water pumps as the requirements differ considerably. Municipal waste water pumps, also referred to as sewage pumps, typically transport the following fluids: raw sewage, as well as storm water.

For industrial waste water pumps the selection of suitable materials is crucial as industrial waste water can be highly aggressive or abrasive. The pump casing can be especially fitted with casing wear rings or wear plates which are made of particularly wear-resistant materials and can be easily replaced.

Clean water pump

Clean water pumps are used in water supply applications for pumping clean or treated water, e.g. drinking water, surface water (rivers, streams, ponds, sea) or groundwater (wells, springs).

The motors of submersible pumps are encased in oil-filled compartments that do not have contact with the substance they are pumping. They have the advantage of being essentially self-priming because they operate below the surface of the media to be pumped.
