Chemical Pumps
Pumping units, designed for transportation of aggressive liquids with mechanical admixtures, containing particles not larger than 0,2 mm. at concentration up to 1000 mg/1 and temperature not higher than 80°C.
Flow-head range - 1,5 - 350 1/s, and maximum head - 470 m.w.c, covered by 50 size types of "E", "KUL", "MTR" and "D" pumps with frequency of rotation: 1470 min-1, 2900 min-1.
Centrifugal pumps. Flange fixing dimensions, corresponding to BDS 3277-84.
Depending on clients' order, the pumps can be coupled with el. Motors for different voltage, frequency, class of insulation - explosion- or gas-proof.
The pumps are tested and approved in compliance with ISO 2548 class "C" for water with temperature 20°C.
The details in contact with the transported liquid, are manufactured from chrome or chrome-nickel steels as per table.
