■Flow rate:Q=250~55000(m³/h)
■Total head:H=8~1.5 (m)
■Speed:n=180~1450rpm
■Fluid s.g.:γ ≤1.5
■Fluid temperature:T=0~180℃
■Fluid viscosity:ν ≤600(mm2/s)
■Pump diameter:Ф250mm~1800mm
■The impeller is high hydraulic efficiency type and is designed to be applicable to the requirements of evaporation system, it is able to adapt the fluctuation of evaporator loading,therefore reduces the energy consumption and increases the output.
■Adopting the adjustable impeller to fit different applications.
■Butt welding and thermal compensation reduces the investment cost.
■Low pump speed and low linear velocity reduces the damage of crystals.
■Pipe hung arrangement solved the stress compensation caused by heat expansion, no need of pump baseplate and expansion joint.
■Slight vibration,low noise,smooth operation,high efficiency and energy-saving.
■Elbow structure for pump body,piece-welded body and casted body for selection.
■Pump impeller is cantilever type with spherical hub,impeller blades are adjustable.
■Pump shaft adopts butt welding workmanship,the wetted parts or possible wetted parts are made from stainless steel or other corrosive materials.
■Mechanical seal and packing seal can be interchangeable.
■Adopting cartridge mechanical seal,reliable and easy for maintenance.
■Enlarged cylinder type bearing housing with oil level glass and oil filler,which extends the bearing life and interval of lubricant changing.
■Pump and be driven by motor through V-belts,gear box or directly through couplings. For pipe hung pump,the universal joint transmission must be adopted if the motor ≥200kW.

ZW chemical axial flow pump is mainly applicable for the applications of big flow rate and low total head, like force circulation pump for evaporator systems:
■Salt-making force circulation pump
■Sodium sulfate force circulation pump
■Aluminum oxide force circulation pump
■Sugar-making force circulation pump
■Chlorine alkali force circulation pump
■MVR water treatment force circulation pump
