Brief Description: 

 

ZMP high pressure self-balancing multistage pump is high pressure multi-stage sectional ring type according to API610. This pump is high efficiency and energy saving. The operation life is 3 times of ordinary centrifugal pump, so reduced customer's maintenance cost. This type of pump is developed based on traditional multi-stage centrifugal pump canceled axial thrust balancing mechanism. The pump is the best to replace the multi-stage pump with balancing pan or balancing drum. Since there is no balancing device, the balancing panfriction loss and balancing back flow are both avoided, the pump efficiency is highly increased by 3~5%, and the pump operation life is also prolonged because balancing device failures are avoided.

Structure Features:

• ZMP series of single or double suction pump has suction nozzle both horizontal or vertical, and discharge nozzle vertical.
• The rotor are composed of shaft, impeller, throttle pressure releasing device, counter impeller, shaft sleeve, bearing collar ring etc. The bearings are thin oil lubrication structure, and the driving end is cylindrical rolling bearing, non-driving end is angular contact ball bearing. Pump working chamber is composed of suction casing, stage casing, discharge casing, second suction casing, guide vane, counter guide vane, intermediate tube etc.
• The sealing between rotating part and stationary part is seals ring and guide vane sleeve. If the seals ring and guide vane sleeve are worn to influence the pump performance, please replace in time.
