Product Overview

GDL series vertical multi-stage pipeline centrifugal pump is a new generation of energy-saving product designed and manufactured by our company based on domestic and foreign pump types, in combination with user's requirements and relevant fire protection standards, and in accordance with JB/TQ6435-92 standard.

This type of pump adopts a vertical segmental external stainless steel shell structure, which makes the inlet and outlet of the pump on the same horizontal line with the same caliber, and can be installed in the pipeline like a valve. It also combines the advantages of high pressure of multi-stage pump, small floor area of vertical pump, and easy installation of pipeline pump. At the same time, because of the hydraulic model, it also has the advantages of high efficiency, energy saving, stable operation, etc., and the shaft seal is wear-resistant mechanical seal, No leakage, long service life.

In order to better meet the requirements of users, our company has also developed GDLS type with upper water outlet, whose inlet and outlet can be installed at different relative positions (0 °, 90 °, 180 °), which is very convenient for use.

This type of pump is mainly applicable to the circulation and pressurization of cold and hot clean water in the high-pressure operation system, the parallel water supply of multiple pumps in high-rise buildings, fire protection, boiler water supply and cooling water systems and the delivery of various flushing fluids.
