- product introduction:DH(V) series split case pump is of single stage, double suction centrifugal pump. Compared with other type of pumps, it features long service life, high effciency, advanced construction, low operation cost, friendly maintenance and service.
Application：
Type DH(V) pump can be used to delivery clear liquids and should not contain solid grain at temperature below 130℃.
·Air-condition cold water circulation.
·Water supply and discharge in factories, mines, urban areas.
·Water supply in power plants, water-conservancy projects as well as irrigation.
·Fire system, ship industry and chemical & oil industry.
Features：
·DH(V) series pump is of single stage, double suction, axial split case, volute centriugal pump. Horizontal installation or vertical installation. Motor of horizontal pump can be installed in the left or in the right. Suction and discharge are horizontally below the pump shaft centreline. When maintenance or service isneeded, just open the pump cover and take out the rotation parts for esay service without dismantle of pipeline and motor.
·The design pressure of pump casing is 1.6 Mpa & 2.5Mpa. In order to meet with different flange standard, suction and discharge flanges can be in conformity with GB, ISO, DIN, ANSI and JIS. Suction & discharge are all set in the casing, so it is easy to maintenance the pump: just open the pump cover, and take out the rotation parts for service without dismantle of pipeline.
·Thicker flange of pump cover is fastened with pump casing by long bolts with advantages of no leakage.lt is very convenient to conduct installation and maintenance work owing to the autocorrelation function of the pump cover.
·High-efficiency double suction impeller, stable operation, low energy cost, low noise, less vibration, and long service life. The pump casing and the impeller may be equipped with sealing rings so as to extend the service life of the impeller. Keep the impeller in dynamic balance to ensure stable vibration-free operation of the pump.
·The pump shaft is totally sealed, no contact with the pumping liquid. it features long service life and no corrosion. As its shaft diameter is large and the distance between bearings small, and there is no vibration in its operation, the rigidity of the shaft is increased, thus extending the service life of the mechanical seal and the bearing. When assembling the rotor components, noadjustment needs to be made; and it is very convenient to disassemble and assemble the rotor components with the prestressing force of the dish spring.
·There is cooling chamber in the bearing unit to ensure Max. pumping temperature 130℃. The driving end of horizontal pump adopting double zanjon ball bearing, the driving end of vertical pump adopting double rowangular contact ball bearings to bear remains of axial impact. Bearings are lubricated by grease. Totally-sealed bearing is an alternative option. the service life of bearings are over 100,000 hours.
·Soft packing seal or mechanical seal (non-balance type). No rotation direction limit of mechanical seal.
