MS Double suction centrifugal pump
Pump Description:
MS type pump is S series of the renewal of energy-efficient products, widely used in modern urban water supply and sewerage, power generation, industrial process water intake, compression, irrigation systems and hydraulic engineering, petrochemical engineering and so on.
MS type pump adopts national standard specification for design, its serialization, standardization, high degree of generalization, superior performance, stable operation, safe and reliable. New structures be used in the design, easy to maintain, repair and maintenance; introducing new material may be applicable multiple media to delivery.

Structure Feature
1. Structure of casing: Open structure in axial, inlet and outlet of the pump both on the pump body, and in the same plane perpendicular to the axis. Easy to lay pipes and repair (when repairing, open the pump cover and rotor parts without removing inlet and outlet of pipes and motor).
2. Structure of rotor: Adopt double-suction impeller, using its symmetric arrangement of leaves to balance the effect of the radial force. Impeller fixed on the shaft relying on either side of the shaft sleeve and sleeve nut, align axial position accurately by adjusting the sleeve nut. Both ends of the shaft support structure connect motor directly through elastic pin coupling, effectively reducing mechanical losses; deep groove ball bearings and grease lubrication insure smooth operation.
3. Vortex structure: Pump body, pump cover and impeller constitute the suction Chamber and water pressure Chamber. Install a seal ring between the suction chamber and water pressure chamber to reduce water leakage from water pressure Chamber back to the suction Chamber, which reduces the capacity of losses, while effective protect the pump body, extending the life of pump case. On in and out of the flange, reserved the installation of spiral hole for vacuum and pressure gauges; on lower portion of in and out of the flange, reserved spiral hole of drainage for easy Automation Control System access.
4. Structure of shaft seal: There are packing seals and mechanical seals, may also adopt soft packing seals according to special requirements. Depending on the media properties water seal water (washing water) can use water of pressure chamber or external supply water.
