This standard specifies the basic parameters, technical requirements, test methods, inspection rules, marking, packaging and storage of rotor-type heavy oil pumps for oil fields. This standard is applicable to rotor pumps that transport media with a temperature of ≤150°C and a viscosity of 0.1 to 10 Pa·s. Its rated flow range is ≤400m^(3)/h; its rated discharge pressure range is ≤5.0MPa.
