♦ The whole series of universal structure design, high degree of generalization, reduce the inventory of maintenance parts for users;
♦ High-precision bearings, strong bearing capacity, long operating life;
♦ Integrated design of engine and pump, low vibration and low noise.
[Application]
♦ It is suitable for transporting clean water and liquids with similar physical and chemical properties.
♦ Flow range: 4~1200m³/h
♦ Head Range: 10~150m
♦ Special working conditions, professional customized services supported
Features:
- Conform to ISO2858(GB5662)and GB/T5656(equivalent to ISO5199)
- Heavy shaft of increased diameter, the bearing capacity of bearings is averagely increased by 75~160%, the life of bearings are tremendously extended.
- Forced internal cooling cartridge mechanical seal and big sealing chamber reduced the possibility of breakdown.
- Easy adjust method of pump rotor part to maintain low pressure of sealing chamber, to reduce the axial force,and therefore guaranteed the stable operation of pump.
- Several transforming designs enlarged the range of application of pump, increased the reliability of pumping special fluids.
- High interchangeability of pump parts reduced the cost on spares parts for clients.
Structure:
- Single stage,single suction,horizontal centrifugal pump. Bracket structure for bearing parts, the bearing housing is supported by the bracket. The axial displacement of pump rotor part can be adjusted by a special bolt. Closed impeller(HZ type),semi-open impeller(HZJ type) and fully opened impeller(HZQ type) are available.
- The impeller is connected with shaft by screw thread, an anti-vortex plate is adopted at the pump inlet to increase the reliability of pump.
- The impeller with rear blades is adopted to balance the axial force at the pump suction. And the gap between the rear blades of impeller and pump cover can be adjusted by a bolt.
- The pump structure is back pull type,the rotor part(impeller,shaft,shaft sealing and bearings) can be removed without dismantling the pipes during maintenance.
- The shaft sealing is cartridge mechanical seal, and can be customized as single mechanical seal, packing sealing and secondary impeller+packing sealing.
Configuration:
Application:
HZseries chemical process pump is suitable to pump clean fluids, fluids with small quantity of small particles and corrosive fluids. The fluids including: inorganic acid,organic acid, petrochemical fluids,organic compounds and other corrosive fluids. The HZ series pump is mainly applicable for:
- Refinery,petrochemical industries,coal mine process industry and low temperature projects.
- Chemical industry,paper-making,paper pulp industry,sugar industry.
- Water treatment plant, seawater desalination projects
- Power plant
- Environment protection projects
- Vessel and offshore industries.
