1.QIZ Monoblock Water pump introduction
QIZ Monoblock close coupled Centrifugal end suction pump is a single stage, single suction pump for pumping clean water and the other liquids physically and chemically similar to the clean water. This pump is suitable for public water supply and drainage duties in industries and land irrigation also in agriculture. It is the closed coupled type 15hp water pump.
2.QIZ Monoblock Water pump Feature
1. Impeller directly mounted on the extended shaft of motor to feature short axial dimensions and compact structure. Pump and motor bearings reasonably configured to effectively balance the radial and axial load in service, thus to ensure smooth operation with little vibration and low noise.
2. Use of mechanical seal or mechanical seal combination for shaft seal, sealing ring made of imported titanium alloy, medium-sized high temperature resistant mechanical seal, and wear resisting seal made of hard alloy to effectively lengthen the service life of mechanical seal.
3. Easy installation and maintenance, with no need to dismantle the pipeline system. And all the rotor parts may be taken out only by taking off the nuts on water pump union base.
3.QIZ Monoblock Water pump Application
Widely used in water works, agricultural irrigation, draining pump station, electric power station, air-conditioning circulation water, industrial water supply system, shipbuilding industry and general use in oil refining industry.
