Detailed Description
1. General
The pump of type IS is a single stage, single suction (axial suction) centrifugal for pumping clean water and the other liquids physically and chemically similar to the clean water. The temperature of liquid shall not be over 80℃. This pump is suitable for public water supply and drainage duties in industries and land irrigation also in agriculture.
Design duty and features: (at design point)
Speed     n:          2900rpm and 1450rpm
Inlet diameter:          50 to 200mm
Capacity  Q:          6.3to 400m3/h
Head     H:          5 to 125m
See Fig 2 and chart 1 for size and performance parameters of IS pump.
Details should be supplied by manufacturer.
Description of pump symbol figures:
For example: IS 80-65J-160A
IS—— Single stage, single suction clean water centrifugal pump
80—— Inlet diameter (mm)
65—— Outlet diameter (mm)
J——Rated speed dropped
160: Nominal impeller diameter
A——A、B、C separately represents that impeller diameter is cut the first the second and the third time
 
2. Construction
IS type pump is designed with performance and dimensions specified to the International Standard ISO 2858. The major components are casing (1) casing cover (2) impeller (3) shaft (4) wear ring (5) shaft sleeve (8) bearing bracket (12) etc. ( See Fig 1 )
IS pump is divided into the casing and the casing cover from the back face of the impeller i.e. back pull-out design.
IS pump has the advantages for ease of inspection and maintenance. When inspection, only dismantle the intermediate connector between pump coupling and motor coupling. The rotating element can be completely removed without disturbing the casing, suction and discharge pipeline and motor.
The pump volute form is composed of casing and casing cover. The rotating element consists of impeller, shaft and rolling bearing. The rotating element is carried by the rolling bearings mounted in a hanging bearing bracket and radial and axial thrust is supported by the bearings.
In order to balance axial thrust, there are both wear rings in front and at the back of the majority of the impeller and the balance hole is on the back shroud of the impeller. The axial thrust of some pumps is not big enough, so there is no wear ring and balance hole at the back of the impeller.
 
  The shaft seal consists of packing gland (9) water seal ring (10) and packing (11) to prevent air from in taking or the amount of leakage. If there is a balance hole of the impeller, cavity for soft packing connects to the impeller entrance. If liquid of the impeller entrance is at vacuum state, it is easy for air entraining along the surface of the shaft sleeve. So water seal ring is in the stuffing box.
Pressure water in the pump volute is led to water seal ring to be sealed. If there is no balance hole of the impeller, liquid pressure at the back face of the impeller is higher than atmosphere. There is no air leakage, so the water seal ring can not be packed.
The shaft sleeve is on the shaft to avoid excessive shaft wear. There is “O” ring between the shaft and the shaft sleeve to prevent air entrance or water leakage along the matched surface. Drive is transmitted from the motor to the pump by a flexible coupling with the intermediate connector. Rotation is clockwise when viewed from the driven end.
See Fig 3 and chart 2 for the pump dimensions. See Fig 5 and chart 4 for dimensions of suction and delivery flange.
