Vertical axial/mixed flow chemical pump
ZLH series vertical axial(mixed) flow pump is also known as salting out axial flow pump and low temperature crystallization axial flow pump. ZLH series vertical axial flow pump is the core equipment of earliest developed, most complete in specifications and biggest flow rate(biggest diameter) for combined soda process in China. The impeller and elbow passage of ZLH series vertical axial flow pump are optimized design with better performance and efficiency. Due to the technologies of adjustable impeller, low linear speed, butt welding shaft and reliable operation, ZLH series was awarded as second prize for technology progress by China Soda Ash Industry Association.There are various materials available for our vertical axial flow pump, including stainless steel SS304, SS316, SS316L, 904L, duplex stainless steel CD4MCu, 2205, 2507, Alloy 20, Hastelloy, Titanium, Monel, Nickel...
■Flow rate: Q=300～8000 （m³/h）
■Total head: H= 1～6 (m)
■Fluid temperature: T= 0～50℃
■Fluid s.g.: γ≤1.4
■Optimized elbow passage of better hydraulic performance.
■Adjustable impeller of high efficiency and wide high efficiency zone.
■Low pump speed design conforms to the technological requirements of salting out and low temperature crystallization.
■Cost saving butt welding technology to satisfy requirements of both transmission strength and anti-corrosion.
■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.
■Special design to adapt to different applications. For example, increasing the pressure of system and increasing the liquid level, forced circulation purpose...
■ZLH series is a typical vertical axial flow pump of vertical installation which takes small room on floor.
■Pump impeller end is immersed in the fluid which enables direct start without filling water or vacuum pumping.
■Simple structure, convenient maintenance.
■Direct coupled transmission or gear box transmission.
■Dynamic sealing+packing for shaft sealing
