ZW type evaporation circulating pump:1、Use
-ZWXII series axial flow pumps are mainly used in large flow, low head occasions, as conveying or forced circulation pumps.
-Adaptable medium temperature 0~180℃.
For example: salt workshop forced circulation pump.
Manganese evaporation workshop forced circulation pump.
Alumina evaporation system forced circulation pump.
Sugar industry evaporation system forced circulation pump.
Forced circulation pump in alkali-making process.
2. Product Characteristics
-Cantilever bend tube structure.
-Optimized hydraulic model design.
-Slow rotational speed and low linear velocity design, small damage to crystals.
The pump shaft adopts a butt-welding process to meet the requirements of transmission strength and wear and corrosion resistance.
-Suspended installation, solving the thermal expansion stress compensation, no pump foundation, no expansion joints on the pipeline.
-Small vibration, low noise, smooth operation, high efficiency, and energy saving.
-Pump long-term continuous operation is reliable, up to one year without maintenance, twenty years of the whole machine life.
-Reasonable pump structure, beautiful, parts, and components coupling fully considered its mounting and dismounting convenient.
3、Product parameters:

4. Product structure
-Pump impeller is cantilever support, spherical hub, impeller vane is adjustable.
-The pump body is designed in the form of a curved pipe with a group welding structure.
The pump shaft adopts butt-welding technology, and stainless steel is used in the contact and possible contact with the medium. Mechanical seal adopts assembled structure, convenient assembly and disassembly, and reliable operation.
-Mechanical seals and packing seals can be interchanged, only a few parts need to be replaced.
The cylindrical bracket supports the rotor parts, and the oil storage chamber of the bracket is enlarged, equipped with an eye-catching oil level observation window and constant oil level oiler, which prolongs the lubrication and maintenance intervals and prolongs the life of the bearings.
The pump and the prime mover can adopt narrow V-belt (15N or 25N type) delta belt transmission, gear variable speed transmission, or direct connection transmission, the pump is suspended mounted (E mounting form), and the motor power ≥200kW adopts universal joint transmission.
