To provide high-quality Water pump products for global customers.

Product Introduction

The DL series vertical multi-stage centrifugal pump is a newly developed segmented centrifugal pump designed to meet the GB/T1051 standard. Due to the use of advanced high-efficiency and energy-saving hydraulic models, this pump has high efficiency and good performance, thus better adapting to customer needs. In addition, DL pumps are vertical and segmented centrifugal pumps, which have the characteristics of safe and reliable operation, long service life, small footprint, and easy installation and maintenance.

DL type pumps are used to transport clean water or other liquids with physical and chemical properties similar to clean water at temperatures between -15 ℃ and+120 ℃. If the liquid contains impurities, the amount of impurities should not exceed 0.1%. Mainly used for supplying domestic and fire-fighting water to high-rise buildings, it can also be used for supplying water to factories, towns, enterprises, and circulating water for low-pressure boilers.

Performance range

Flow rate	4—120m³/h
Lift	18—261m
Motor power	1.1-132KW
Product standard	JB/T1051-93

The DL series vertical multi-stage centrifugal pump is an efficient, reliable, and compact pump equipment suitable for various liquid transportation scenarios.

Main features

Structural features:
Adopting a vertical multi-stage and multi-stage structure, consisting of an inlet section, an interruption section, and an outlet section, connected by screws.
Each stage is equipped with an impeller and guide vanes, with the suction port located at the lower part of the pump and the discharge port located at the upper part, both in a horizontal direction.
The axial force is solved by hydraulic balance method, and the residual axial force is borne by the ball bearing.
The shaft seal adopts soft packing or mechanical seal, and the motor is equipped with a rain cover, suitable for outdoor use.
The curve is stable and the operating range is wide.
Maximum system working pressure<2.5Mpa, smooth operation performance characteristics:
The flow range is 4.2-504m ³/h, the head range is 22-239m, and the supporting power is 1.5-450KW
Adopting efficient and energy-saving water conservancy models, with high efficiency, low noise, and low performance.
The medium temperature generally does not exceed 80 ℃ (DLR type can reach 120 ℃), and the environmental altitude is less than 1000 meters.
Scope of application:
Mainly used for water supply in high-rise buildings, fire protection systems, centralized heating, air conditioning systems, and water supply in industrial and mining enterprises.
Suitable for industrial and urban water supply and drainage, long-distance water supply, heating, boiler water circulation boosting, and equipment matching.
The conveying medium is clear water or a liquid with physical and chemical properties similar to water, without solid particles or fibers.

Summary: DL series pumps are widely used in the fields of construction, industry, and municipal engineering for liquids due to their high efficiency, energy saving, compact structure, and stable operation.
