gdl multi-stage pump model parameters

26 Mar 2021Email

The gdl multi-stage pump is a vertical multi-stage segmented centrifugal pump using an excellent hydraulic model, which has the characteristics of energy saving, small footprint, convenient installation and stable performance. The outer jacket is made of 1Cr18Ni9Ti stainless steel, and the shaft seal is made of wear-resistant mechanical seal, which has no leakage and long service life. According to user requirements, stainless steel 306 or 316L can be customized. It is mainly suitable for the circulation and pressurization of hot and cold 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 washing fluids. The model parameters of gdl vertical multistage centrifugal pump are as follows:

Technical parameters of gdl vertical multistage centrifugal pump: 　　

Flow rate: 2-200m³/h; 　　

Head: 23-230m;

Efficiency: 23%-78%

Model description of gdl vertical multi-stage pump: 　　

For example: 100GDL72-16×5 　　

100-Inlet and outlet diameter (mm) 　　

GDL- vertical multistage pipeline centrifugal pump 　　

72-single-stage head (m) 　　

16-Design point nominal flow rate (m3/h)

5- The pump has 5 stages
