■Flow rate: Q=300～8000 （m³/h）
■Total head: H= 1～300 (m)
■Speed: n=180-1450rpm
■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
