HS double suction centrifugal pump

Product overview 
HS type horizontal middle pump is single stage non self priming centrifugal volute pump between shafts. The open-cen ter design facilitates the removal of the upper pump cover and the internal components of the pump (bearings, wear rings blades and shaft seals) without interfering with the motor or piping. Bearing housing design is independent, no need toemove the top cover can carry out maintenance maintenance double volute design to reduce the radial load of the shaf extend the service life of the bearing and the front, reduce wibration, so that the pump quiet operation.


The working conditions 
Pump conveying liquid temperature range for the largest -25℃
to+140℃, the concrete allows for conveying liquid range depends on the pump body and machine sealing material.
Deliver clean water without particles Application field Widely used in water supply and drainage, air conditioning water, fire water, municipal water supply Scope of supply Pump set (pump head, motor, coupling, coupling housing). Base)Installation instruction.

Product features 
Shaft sleeve: replaceable shaft sleeve is available in a variety of materials. The shaft sleeve is mounted on the shaft to protect it from wear and tear.
Mechanical shaft seals: pumps are available in a variety of mechanical seals to meet application requirements.
Inlet baffle: the unique integral casting inlet baffle guides the flow of fluid more concentrated to the impeller suction inlet and the internal fluid is gradually accelerated to restrain the turbine and ensure quiet and smooth operation.
Sliding bearing: reduce the distance between bearings, so as to reduce the deflection of the shaft in the machine seal, extend the service life of the machine seal, facilitate maintenance reduce the operating cost.
Shaft: bolted design greatly reduces pump vibration while minimizing shaft deflection to extend bearing and mechanica seal life Bearing: the shortest bearing span and thickened axle diametel ensure the bearing life (B-10) of more than 50000 hours.
Pump body seal ring: replaceable seal ring protects the pump body from wear and tear, and through the appropriate clearance of simple adjustment, reduce maintenance costs and maintain efficient pump operation.
Pump body: the inlet and outlet flanges are integrated with the pump body. To ensure that the whole rotor parts are disassem bled and assembled without disassembling the pipeline. The pump body is installed with foot support to reduce vibration.
Suction chamber: precise geometric design improves hydraulio efficiency and reduces NPSHr.
Double vortex shell structure: HS(V) compensating double vortex shell design can effectively eliminate the radial load by balancing the pressure generated when the liquid flows into the pump body. This balancing characteristic prolongs the service life of the seals and bearings, reduces vibration and provides balanced operation. The double vortex shell improves the efficiency by providing two independent vortex channels in the pump body to carry out the reflux meter. When the outle diameter is more than 100 mm, the double-vortex shell pump can be selected Bearing block: HS(M) unique one-piece bearing block in processed in 360 degrees and connected to the upper and lower parts of the pump body through screw inspection, so a to optimize the connection and extend the service life of the bearing. This compact design limits shaft deflection by support.
ing a rigid shaft. Madular bearing and sealed chamber desigr for easy maintenance and inspection of seals, bushing and bearings without the need to remove the pump cover Impeller: HS(V) pump adopts the design method of t piece paying special attention to the matching of impeller and pump shell, so as to produce the comprehensive result of wide and efficient zone and low cavitation zone, hydraulic balanco double-suction impeller and radial load balance, so as to make the running of HS(V) pump stable, minimum vibration and reduce the running cost.
