Double Foundation Vertical Axial Flow Pump

Double Foundation Vertical Axial Flow Pump

Short introduction:

ZLH collection axial circulation pump is also known as salting out axial flow pump and minimal temperature crystallization axial flow pump. ZLH series axial movement pump is the main tools of earliest produced,most full in specs and greatest flow fee(biggest diameter) for combined soda method in CZPT. The impeller and elbow passage of ZLH series vertical axial stream pump are optimized layout with better performance and efficiency. Owing to the technologies of adjustable impeller,lower linear velocity,butt welding shaft and reliable procedure,ZLH sequence was awarded as 2nd prize for technology progress by CZPT Soda Ash Industry Affiliation.


Flow rate: Q=300~8000 (m³/h)
Total head: H= 1~6 (m)
Pace: n=180-1450rpm
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 CZPT.And there are plenty of real sales achievements from flow rate 300 m3/h to 8000 m3/h.
  6. CZPT 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.
