DLY50-25*2 DLY vertical multistage submerged oil pump Description

Vertical multistage submerged oil pump

Multi stage submerged pump is a new type of oil gathering pump used in oil fields. Its characteristic is that it occupies a small area and is easy to install and maintain in the field. This series of pumps can fully meet the current needs of oil gathering and sewage discharge in oil fields.

DLY multi-stage submerged pump is used to transport crude oil and oil-water mixed media collected from oil wells and oil stations. It is also suitable for use in oil pipelines and can meet the needs of oil production plants, chemical plants, refineries, and other units to transport various types of oils and similar liquids,

It can also be used for conveying clean water and similar media.

Performance range of DLY vertical multi-stage submerged pump

（1） Flow range: 5-300m3/h Head range: 15-300m Viscosity range: 0-60cst (centistokes) Medium temperature: 0-200 degrees Celsius

Characteristics of vertical multi-stage submerged pump

（2） The multi-stage submerged pump product is a vertical single suction multi suction segmented centrifugal pump. The DLY pump has a suction inlet located at the bottom and vertically downwards, and a discharge outlet center arranged horizontally.

This series of pumps have the advantages of small size, small floor area, low noise, no radial force generated during radial guide vane operation, stable operation, high efficiency, and few exposed parts.

（3）Transmission of multi-stage submerged pump

The multi-stage submerged pump is driven by an outdoor vertical explosion-proof motor installed on the motor frame through a coupling. From the motor end, the pump rotates counterclockwise.

（4） Multistage submerged pump shaft seal

The multi-stage submerged pump adopts a packing seal with a low-pressure outlet shaft structure, which is safe and reliable without leakage.

（5） Bearings and balancing devices for multi-stage submerged pumps

The upper part of the pump shaft is supported by double row centripetal thrust ball bearings, while the lower part of the pump shaft is supported by wear-resistant alloy sliding bearings. The axial force of the pump is balanced by a balance drum or balance hole, and the residual axial force is,

Undertaken 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 multi-stage submerged pump can be selected according to different media of users, such as ductile iron QT600-3 stainless steel 1Cr18Ni9Ti or cast iron HT200.
