Horizontal Irrigation Centrifugal Water Pump
Horizontal Irrigation Centrifugal Water 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.
Horizontal Irrigation Centrifugal Water Pump is also very easy to be installed and maintained. Back pull-out design, driven through flexible coupling, so that pump casing and motor can remain in position while other spare parts are removed.
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.
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.
