SG type pipeline pumps (hereinafter referred to as the pumps) is big yuan pump technology personnel experts selected jointly domestic water pump hydraulic model according to international standard outstanding ISO2858 and national standard JB/T53058-1999 specified performance parameters, combining production experience and the company for the design of new generation energy-efficient products, low noise, specifications, stable performance can replace conventional centrifugal pump in all situations. The present application than horizontal centrifugal pump more superiority. With the advanced mechanical seal, a motor shaft installed directly impeller, so have less leakage presisely, high efficiency and power consumption provinces, compact, small volume, light weight, convenient, and according to the decoration of the head and flow to adopt and series using etc. The pump as conventional centrifugal pump, instead of the products of the various old-fashioned pump, has been widely applied in industries, is the general trend.
