Single Foundation Vertical Axial Flow Pump for Flood Control

Single Foundation Vertical Axial Flow Pump for Flood Control

Short introduction:

ZLH series axial stream pump is also known as salting out axial circulation pump and low temperature crystallization axial flow pump. ZLH collection axial stream pump is the core tools of earliest produced,most full in specifications and biggest movement rate(largest diameter) for merged soda process in CZPT. The impeller and elbow passage of ZLH series vertical axial movement pump are optimized design and style with far better overall performance and effectiveness. Because of to the systems of adjustable impeller,reduced linear velocity,butt welding shaft and trustworthy operation,ZLH collection was awarded as second prize for technological innovation progress by CZPT Soda Ash Sector Affiliation.


Flow rate: Q=three hundred~8000 (m³/h)
Total head: H= 1~6 (m)
Speed: n=a hundred and 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 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.
