China Made Vertical Axial Flow Pump for River Water

China Made Vertical Axial Flow Pump for River Water

Short introduction:

ZLH series axial flow pump is also recognized as salting out axial movement pump and reduced temperature crystallization axial movement pump. ZLH sequence axial stream pump is the core gear of earliest designed,most full in requirements and largest movement fee(greatest diameter) for combined soda method in China. The impeller and elbow passage of ZLH series vertical axial stream pump are optimized style with better performance and performance. Due to the technologies of adjustable impeller,reduced linear speed,butt welding shaft and dependable procedure,ZLH series was awarded as second prize for technological innovation development by China Soda Ash YWIN Association.


Flow rate: Q=three hundred~8000 (m³/h)
Total head: H= 1~6 (m)
Velocity: n=one hundred eighty-1450rpm
Fluid temperature: T= 0~50ºC 
Fluid s.g.: γ≤1.four


  1. Optimized elbow passage of better hydraulic performance.
  2. Adjustable impeller of high efficiency and wide high efficiency zone.
  3. Low pump speed design conforms to the technological requirements of salting out and low temperature crystallization.
  4. Cost saving butt welding technology to satisfy requirements of both transmission strength and anti-corrosion.
  5. This product is adopted in 95% combined soda process in China.And there are plenty of real sales achievements from flow rate 300 m3/h to 8000 m3/h.
  6. Special design to adapt to different applications.For example,increasing the pressure of system and increasing the liquid level,forced circulation purpose…


  1. ZLH series is a typical vertical axial flow pump of vertical installation which takes small room on floor. 
  2. Pump impeller end is immersed in the fluid which enables direct start without filling water or vacuum pumping.
  3. Simple structure,convenient maintenance.
  4. Direct coupled transmission or gear box transmission.
  5. Dynamic sealing+packing for shaft sealing



  1. ZLH series is suitable for applications of big flow with low total head.
  2. ZLH series is able to pump clean water,sewage water with small particles and chemical process fluids with small particles.
  3. ZLH series is especially suitable for salting out and low temperature crystallization of combined soda process.
