Single Stage Double Suction Split Casing Pump


Description of Single Stage Double Suction Split Casing Pump

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 of 1990's 20th century.

Application Area of Single Stage Double Suction Split Casing Pump

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.

Permitted testing pressure: ≤ 3.75 Mpa

Structural Characteristics of Single Stage Double Suction Split Casing Pump

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 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



Q: Can your pumps mount Eff.1 motors

A: Currently, only on request though this will shortly be a CNBM standard.

Q: Are your pumps protected against dry running?

A: No, unprotected centrifugal pumps are not generally designed for dry running. It is important to give us or your dealer as much information as possible about the system in which the pump is used. Inlet pressure, the type of liquid to be pumped, together with relative density, viscosity and temperature, for example, are required in order to allow CNBM to recommend the right pump with the right gaskets for a long operating lifetime.

Q: How can I get trained on CNBM products?

A: Yes, we provide training courses in our factory (products, general and specific pump technology, hydraulics, and practical applications). Please consult your sales manager or get in touch with our headquarters for more information.

Q: Are your pumps cheaper than those of your competitors?

A: CNBM aims to give its customers the highest standards of quality and service and delivery times, all at a reasonable price.
