Самовсасывающие центробежные насосы для сточных вод

Description EJ pump is designed referring to European standard of performance and dimensions. This is a series of self-priming sewage pumps. Pump has maintenance holes outside the casing which enable convenient maintenance and cleaning; meanwhile, wear plate, the other one advanced device, would greatly prolong the whole service life. EJ pumps are used for pumping mixtures containing abrasive solids up to a viscosity of 50mm2/s. They are applied in many fields, such as industry, civil engineering, marine, waste treatment and so on. As self-priming sewage pumps, they can deal with different neutral, alkali liquids clean or dirty: liquids mixed with sand, mud or other solids in suspension; low viscosity petroleum products; lime milk, caustic soda and waste water resulted from washing, cooling, circulation, purification or emergency. Pump performance can be adjusted into different levels by speed (Rpm) to meet different requirements.
