Today, let's take a look at the structural composition of horizontal single-stage centrifugal pump:

Pump housing:
Generally, the inner cavity of the volute pump casing is a spiral liquid channel, which is used to collect the liquid thrown from the impeller and lead it to the diffusion pipe to the pump outlet. The manufacturer of the horizontal single-stage centrifugal pump tells you that the pump casing bears all the working pressure and the heat load of the liquid.
impeller:
The impeller is the only working part, and the pump does work on the liquid through the impeller. The manufacturer of horizontal single-stage centrifugal pump tells you that there are three types of impellers: closed type, open type and semi-open type. The closed impeller consists of blades, front cover and rear cover. The semi-open impeller consists of blades and rear cover. The open impeller has only blades and no front and rear cover plates. Closed impellers are more efficient, and open impellers are less efficient.
Seal ring:
The function of the sealing ring is to prevent the internal leakage and external leakage of the pump. The sealing ring made of wear-resistant material is inlaid on the front and rear cover plates of the impeller and the pump casing, and can be replaced after wear.
Shaft and Bearing:
The impeller is fixed at one end of the pump shaft, and the coupling is installed at the other end. The manufacturer of horizontal single-stage centrifugal pump tells you that according to the size of the pump, the bearing can choose rolling bearing and sliding bearing.
Shaft seal:
There are generally two types of shaft seals: mechanical seals and packing seals. The manufacturer of horizontal single-stage centrifugal pump tells you that the general pump is designed to be equipped with both packing seal and mechanical seal.
