1、 Overview of Multi stage Pump Products:

CHL, CHLK, and CHLF (T) lightweight horizontal multi-stage centrifugal pumps use maintenance free mechanical seals. The overcurrent components of multi-stage pumps are made of stainless steel materials (304 or 316), which have the characteristics of low noise, light corrosion resistance, beautiful appearance, small size, light weight, and long service life. Shanghai Yugong Pump Industry, a water pump manufacturer in Shanghai, welcomes new and old users to purchase.

2、 Application scope of multi-stage pump:
CHL, CHLK, and CHLF (T) multi-stage pumps are mainly used for household central air conditioning circulation and industrial liquid transfer. Such as the circulation and pressurization of demineralized water, softened water, purification systems, light oil, etc.  
1) Small central air conditioning cycle
2) Cooling system
3) Industrial cleaning
4) Water treatment (purification of water)
5) Aquaculture
6) Fertilization/metering system
7) Environmental Applications

3、 Working conditions of multi-stage pump:
A liquid that is thin, clean, non condensable, non explosive, and does not contain solid particles or fibers.  
Liquid temperature: Room temperature type -15 ℃ to+70 ℃
Hot water type+70 ℃ to+110 ℃
Maximum ambient temperature:+40 ℃
