32mm outlet centrifugal water pump
32mm outlet 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.
32mm outlet 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.
Running and Maintenance
1). Readings by the meters are very important in starting and running. Care must be taken to heating, leakage, vibration and noise. Abnormal cases should be handled immediately on discovery.
2). Bearings are not allowed to work at the temperature 40℃ higher than the temperature around, and the Max. temperature is 80℃.
3). In normal cases, a steady drip from the gland should be in a small amount, at about 60 drops per minutes while almost non-leakage from mechanical seal.
4). Lubrication should be 4# Calcium Base Grease or SAE20W Oil. Pumps working at 2900 rpm should be replenished with new oil or grease every period of 2500 working hours, 1450 rpm ones should be replenished every 5000 working hours. Ball bearings should be dismantled and replaced by the new ones every 10000 working hours, and also oil cup should be thoroughly cleaned out and filled with fresh lubrication.
