Product details
1、 Overview of Multi stage Submerged Pump
Submerged multi-stage pump is a new type of oil gathering pump used in oil fields. Its characteristics are small footprint, easy field installation, and convenient operation and maintenance. This series of pumps can fully meet the current needs of oil field oil collection and discharge of dirty oil and sewage.
DLYUnderwaterMulti stage pumps are used to transport crude oil and oil-water mixtures collected from oil wells and oil stations, and are also suitable for use in oil pipelines. They can meet the transportation needs of various types of oils and fats in oil production plants, chemical plants, refineries, and other units,
It can also be used for conveying clean water and similar media.

3、 Characteristics of vertical multi-stage submersible pump
（2） The multi-stage submersible pump product is a vertical single suction multi suction segmented centrifugal pump,DLYThe suction port of the pump is located at the bottom and vertically downward, while the center of the discharge port is horizontally arranged.
This series of pumps has the advantages of small size, small footprint, low noise, no radial force generated during radial guide vane operation, stable operation, high efficiency, and few exposed parts.
（3） Multi stage submersible pump transmission
The multi-stage submersible pump is driven by an outdoor vertical explosion-proof motor installed on the motor frame through a coupling, and the pump rotates counterclockwise when viewed from the motor end.
（4） Multi stage submersible pump shaft seal
The multi-stage submersible pump adopts a packing seal with a low-pressure outlet shaft structure, which is safe, reliable, and leak free.
(V)UnderwaterMulti stage pump bearings and balancing devices
The upper part of the pump shaft is supported by double row radial thrust ball bearings, and the lower part of the pump shaft is supported by wear-resistant alloy sliding bearings. The axial force of the pump is balanced by the balance drum or balance hole, and the residual axial force is,
Supported by the upper bearing. The upper bearing is lubricated with grease or thin oil, while the sliding bearing is lubricated by the conveyed medium.
（6） The material of the multi-stage submersible pump can be selected according to different media of the user, such as ductile ironQT600-3stainless steel1Cr18Ni9TiOr cast ironHT200。
