Product details
Description
Stainless Steel Horizontal Multistage Pump is a centrifugal pump, which is designed with two or more impellers. Depending on the configuration, the impellers might be mounted on the same or different shafts. If high pressures at the outlet are required, impellers can also be connected in series whereas for high flow output, they are typically connected parallel.
Using a multistage centrifugal pump to develop high pressures on a common shaft within the same casing is more economical than a pump with just one impeller. As part of the pump design, channels within the pump casing work by routing the discharge of one impeller to the suction of another.
Liquid enters the pump and then passes through the multiple impellers in a series, going from the left to right. from there, water passes from the volute that surrounds the volute of one impeller to the suction of the next impeller. Most pumps of this kind are single-stage there are many times when a multistage centrifugal pump is the better solution.
Stainless Steel Horizontal Multistage Pump can be used for oil multistage pump, chemical multistage pump, sewage and seawater multistage pump, and so on.

Construction
DF Anti Corrosive Multistage Pump is consisted of stator, rotor, bearing, shaft seal.
1. Stator: consisted of suction casing, discharge casing and diffuser. The casing are held together by external tie rod.
2. Rotor: consist of shaft, impellers, balance disc and shaft sleeve etc.
3. Bearing parts: consisted of bearing housing, bearing and bearing cover. It's generally rolling bearing lubricated by grease.
4. Shaft seal: packing seal or mechanical seal.
