pumps such as ADP are designed to pump household, industrial wastewater and other contaminated liquids with a hydrogen indicator (pH) from 6 to 8.5, with a kinematic viscosity of not more than 1 × 10 -6 m 2 /s, density up to 1050 kg/m 3 , temperature up to 35 ° C, with the content of abrasive particles in volume of not more than 1 %. They are used at treatment facilities of cities and industrial areas.
centrifugal vertical pumps with a single -sided entrance work wheel. The drive is an electric motor. Water to the pump is brought through a metal knee. Sliding guide bearing is lubricated with water with a content of suspended particles of not more than 50 mg/l, consuming 1 l/s, 1 kgf/cm pressure 2 more than in the pump.
sealing shaft oilcopod or end rubber.
the conditioning of the pump with the addition of climatic design and the placement category according to GOST 15150-69:
- s - for waste liquids;
- d - dynamic;
- in - vertical;
- numbers in the numerator-feed, m 3 /h;
- numbers in the denominator - pressure, m.
