Chemical mixed flow pump
The hydraulic model of ZHH stainless steel mixed flow pump is optimized by CFD, with the advantages of stable, high efficiency, energy-saving and low operating cost. The ZHH series has full specifications, its pump diameter is from 200 mm to 900 mm, and therefore is able to satisfy the different capacity of various process. It is suitable for the fluid circulation of ammonium phosphate and potash fertilizer process, and it is the most ideal pump for such processes. ZHH mixed flow pump can be also used in the similar chemical applications to form the forced circulation of big flow of corrosive fluids with suspending particles.
■Flow rate: Q= 200～8300（m³/h）
■Total head: H= 5～19 (m)
■Pump speed: n=490～1450rpm
■Fluid s.g.: γ ≤1.5
■Fluid temperature: T=0～105℃
■Pump diameter: 200～900mm
■The hydraulic model is optimized by CFD, with excellent anti-cavitation performance.
■Elaborate design and manufacturing based on the fluid requirements of ammonium phosphate and potash fertilizer process, is able to satisfy various capacity requirements.
■The rotor part can be adjusted by the bearing housing, which enables the convenient method to recover the pump performance after slight abrasion of pump.
■Axial direction adjustable rotor part. The gap between the impeller and the front cover can be adjusted to enable stable operation at high efficiency.
■Pump diameter from 200 mm to 900 mm. A lot of real sales achievements for each specification.
■The discharge direction can be customized based on the requirements of process.
■Horizontal,single stage,single suction,cantilever type,volute casing,direct coupled transmission.
■Back pull design. During maintenance,the rotor part plus the pump rear cover can be pulled out from the casing without dismantle the inlet and outlet pipes.
■Pump shaft sealing consists of dynamic seal and packing.
■Bearing housing is back pull structure,and connected to pump casing by pump rear cover.
