High quality fire water pump diesel engine

HS(V)type series pump is new generation single stage double suction split casing centrifugal pump that is designed and produced by foreign advanced manufacturing technology .
Application Area
HS(V) type series pump is mainly used in water supply plants,power stations,industry water supply system,air conditioning circulation water,building water supply,irrigation,pump stations,and shipping industry.

Structural Characteristics

1,Compact structure
Nice appearance,good stability and easy installation.

2,Operate steadily
The double suction impeller which is optimum and designed by computer,and has a large inlet flowing area.The clapboard is set at packing box of inlet flow passage,it makes no vortex at inlet of pump.It adopts resin sand moulding and high quality cast technology to make the inner surface of pump casing and the surface of impeller smoother than before.Through above measures,we make pump operate with no vortex,operate smoother and have remarkable erosion-resistant ability and high efficiency.

3,Bearing
Excellent bearing is used to assure the steady operation,low noise,long service life.Grease lubrication and closed structure is used.If thin oil lubrication structure is needed,a constant level oil cup shall be equipped.

4,Shaft seal
Mechanical seal or packing seal shall be used.These two kinds of seal are all installed in the removable packing box,which is convenient to assembly and maintenance.The packing gland of pump is removable and open,which assures enough room for maintenance and repair.

5,Impeller
The latest technology of Sanlian Company is adopted as well as the best hydraulic model,which makes the double suction impeller can balance the axial force automatically.

6,Shaft
Shaft is completely sealed without contacting the medium or corrosion.The length of the shaft is shortened compared with that of S,SH type pumps,and it is hard with no vibration.A replaceable shaft sleeve is installed on the shaft.There is no thread on the shaft,and o-ring structure is adopted to assure shaft and bearing do not contact the medium to improve the service life.It is easy to assemble without adjustment.Pump rotor part shall be installed with elastic prestressing force,which makes the installation and disassembly much easier and more convenient.

7,Casing
For the pump of high head,double split casing passage is adopted,which counteracts most of the radial force and prolongs the life of bearing on two sides.

According to the different mediums and using requirements,main parts of the pump can adopt various materials.
