QIG Vertical Pipeline Water Pump

1.QIG Vertical Pipeline Water pump introduction



QIG Vertical Pipeline Water pump is a single stage, single suction vertical 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.

2.QIG Vertical Pipeline Water pump Structure and Feature

1. Vertical structure, inlet and outlet given the same diameter and located on the same centerline, to be mounted in pipeline in the way as a valve, compact and smart appearance, little floor space required, low construction cost, and to be used outdoors if provided with a protective cover.
2. 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.
3. 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.
4. 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 pump union base.

3.QIG Vertical Pipeline 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.
