APPLICATION
DMR series double casing multi-stage centrifugal pump is primarily used within petroleum production, petrochemical production and other chemical production process for the transportation of pure liquids. Media temperature range from 0 ℃ to 210 ℃.
CHARACTERISTICS:
Multi-stage double casing;
Horizontal arrangement, sectional designed;
Top suction and top discharge;
Axial thrust compensated by balancing devices;
Clockwise rotation viewed from couplings;
Fully comply with API standard.
PERFORMANCE DATA:
Capacity: 30 ~ 750 m3/h
Head: 600 ~ 2850 m
Discharge Pressure: 6 ~ 28 Mpa
DESIGNING FEATURES:
Axial thrust balanced by balancing devices with extra axial thrust which will occur during special circumstances balanced by thrust bearing;
Inner-casing easily removable without disconnecting pipelines;
Couplings: Flexible diaphragm couplings used for low speed operation; flexible diaphragm couplings and speed-increasing gearbox are employed for high speed operation;
