QS Series Agricultural Irrigation Pump
This pump characteristics is large capacity, split casing type
pump, simple structure, convenient maintenance, there is no need to
remove pipe and electric motor when maintenance. Long service life.
Pump performance design:
Solid size: 3mm
Pump Size: Φ150-Φ1200
Temperature range: ≤0~+80℃
Operation Pressure: ≤1.6MPa
Model QS pump is a single-stage double-suction horizontal split
centrifugal pump and used to transport pure water and the liquid of
both physical and chemical nature similar to those of water, the
maximum temperature of which must not be over 80℃ , suitable for
irrigation of farming land and carious hydraulic projects, water
supply and drainage in factories, mines, cities and electric
stations, waterlogged land drainage etc.
1. Pump Casing
The volute casing is split on the horizontal centerline with the
suction and discharge nozzle cast integral with the pump casing.
The upper casing is accurately located on the lower half by the use
of dowel pins. The upper casing can be removed to inspect the
interior of the pump without disturbing the pipe connections or
pump alignment. The suction and discharge flanges contain tapped
holes for vacuum and pressure gauge. At the bottom of the flanges,
there are tapped plugs for water drainage.
The impeller is static-balance calibrated, fixed with the muff and
the muff nuts in both sides and its axial position can be adjusted
via the nuts and axial force gets balanced by means of the
symmetrical arrangement of its blades, there may be residual axial
force which is borne by the bearing at the axle end.
The pump shaft is supported by two single-column centripetal ball
bearings, which are mounted inside of the bearing body on both ends
of the pump and lubricated with grease. The dual-suction seal ring
is used to reduce the leak at the impeller
4. Seal Type
There is gland seal type and mechanical seal type.
Direction of Rotation
The pump moves CW viewing from the clutch to it. The pump moving
CCW can also be produced.
General material is cast iron, main include pump casing, pump
cover, impeller, seal ring and shaft sleeve, shaft is carbon steel.
We could also produce as your requirements, such as nodular cast
iron, cast steel, bronze and stainless steel etc.
