DLY Vertical Multi-Stage Submersible Pumps

Vertical Multi-Stage Submersible Pump Features

(II) The multi-stage submersible pump is a vertical single-suction, multi-suction, segmented centrifugal pump. The DLY type pump's suction inlet is located at the bottom and extends vertically downward, with the discharge outlet centered horizontally.

These pumps in the series feature compact size, minimal footprint, low noise, no radial force generated during radial guide vane operation, stable performance, high efficiency, and minimal exposed parts.

(Multiple Stage Submersible Pump Drive)

The multi-stage submersible pump is driven by an outdoor-type vertical explosion-proof motor mounted on the motor frame, powered through a coupling. The pump rotates counterclockwise when viewed from the motor end.

(4) Multi-stage Submerged Liquid Pump Shaft Seal

Multi-stage submersible pumps feature stuffing box seals with a low-pressure shaft structure, ensuring safety and reliability with no leakage.

(Five) Multi-stage Submerged Pumps Bearings and Balancing Devices

The upper part of the pump shaft is supported by a double-row radial thrust ball bearing, the lower part by a wear-resistant alloy sliding bearing. The axial force of the pump is balanced by a balancing drum or balancing holes, with any residual axial force...

The upper bearing supports it. The upper bearing is lubricated with grease or thin oil, while sliding bearings are lubricated by the medium being conveyed.

(Six) Multi-stage submersible pump material: Available in various materials based on the customer's medium, such as cast iron QT600-3, stainless steel 1Cr18Ni9Ti, or cast iron HT200.
