Used for pumping of oil, oil products, liquefied hydrocarbon gases and mediums which contain harmful agents of 2, 3, 4 Danger Class, with density of 600...1900 kg/m3, kinematic viscosity coefficient not more than 132 cSt, solid inclusion volume concentration of not more than 2% and size of not more than 0,2 mm at temperature range from -40 to +400°С.
High efficiency at low power inputs. Russian or foreign electromotors. Pump units are furnished with up-to-date lamellar couplings that reduce vibration and pump loads. No liquid cooling system of pump and seal bearing assembly. High operability due to reduced number of seal assemblies, usage of vibromonitoring system and direct measurement temperature control of bearing assembly. Usage of “tandem” mechanical seals with minimal leakage rate (max. 0,002 l/h).
