Petroleum centrifugal pumps of types HT
Petroleum centrifugal pumps of type HТ and pump units on their base are designed for pumping oil, liquefied petroleum gas and petroleum products density of no more than 1200 kg/m3.
The pumps are manufactured in climatic design У, T, category 2, 3, 4 according to GOST 15150.
The pumps are designed to work outdoors and in areas where conditions may cause the formation of explosive mixtures of flammable gases or vapours with air, category IIA, IIB according to GOST R 51330.11 and explosion hazard groups T1, T2, T3, T4 GOST R 51330.5.
The pumps are designed to work in areas of seismic activity which does not exceed 8 points on the Richter scale.
The pumps are equipped with bearings of SKF, FAG, Nachi.
