Brief Description:
IS pump complies fully to the European Standard BS EN733 / DIN24255 of performance and dimensions.
They are used for pumping clean water or liquids similar to water, achieving wide application in plants,
mines, city water supplies, air-conditioning coolers, firefighting system and irrigation.
Pumps of the same model have different performance levels basing on different diameter after impeller
trimming. Overall the whole series, there are only four sizes of shaft and five of bearing housing. As long
as their bearing housings are of the same size, different pumps can interchange chief parts such as shaft,
shaft sleeve, shaft seal, impeller nut, etc.
IS pump is also very easy to be installed and maintained. Back pullout design, driven through flexible
coupling, so that pump casing and motor can remain in position while other spare parts are removed.

2. Assembly and Disassembly
Ensure no parts are missing or defective before assembly, wipe every part clean then start.
1). Tighten the bolts, screws and other fasteners to each relevant assembly parts.
2) .Lay O rings, gaskets, felted wool or other sub-seals in each relevant assembly parts.
3) .Place wearing ring and gaskets into casing cover.
4) .Mount ball bearings to shaft, and joint shaft and bearing housing together, close bearing cover with
bolts then put slinger onto shaft.
5). Depress stationary seal ring into mechanical seal cover, put seal cover,mechanical seal,shaft sleeve
one by one onto shaft.
6). Fasten casing cover onto bearing housing by fastening bolts, place key into shaft, set impeller on
key, put lock washer and impeller nut onto shaft against impeller and tighten them.
7). Fix all the assembly parts where mentioned above into volute casing, tighten all the bolts and screws
for volute casing, casing cover and mechanical seal.
3. Installation
Correct way of pump installation makes great sense of stable performance and long service life. All the
procedure of mounting and adjusting should be carried out carefully.For outline and dimension, see the
outline picture and dimension table.
Mounting and adjusting
1). Remove all the dust and dirt on base plate then place it onto ground foundation.
2). Check foundation level by level meter, iron wedge or steel shims can be used for adjustment.
3). Pour concrete into baseplate and foundation bolts holes.
4). Check foundation bolts to see if it is loose or not after concretion, and then tighten the bolts, check
level again.
5). Clean the mounting surfaces of baseplate, pump foot and motor foot, and fix pump and motor onto
baseplate.
6). Make sure the clearance between couplings is left from 2~4mm. The centerline of pump should be
in alignment with that of motor, axial and radial tolerance is 0.2mm. Shims are available for alignment.
This pump casing can be installed by electric motor or diesel engine.the pictures are showed is for reference:
