Products Description
EAZS series are Close-coupled type of EA series.NO need to use couplings and motor shaft is pluged into pump shaft to ensure concentricity and shorten the axial length.The motor is directly coupled to the pump body, eliminating the coupling and bearing housing commonly found in traditional pumps. This design greatly shortens the overall length of the pump, reduces floor space, and also reduces the complexity of installation and maintenance. This makes the close-coupled end suction centrifugal pump particularly popular in situations where space saving and simplified operation are required.
Highly interchangeable parts,space saving,various applications in plants,mines,city water suppliers,fire-fighting systems,air-condition systems and irrigation.
Due to the close-coupled design, the overall structure of the pump is simplified, reducing the number of failure points. This not only improves the reliability of the pump, but also reduces the cost of repair and replacement parts. In addition, the close-coupled design makes the pump alignment more accurate, reduces vibration and noise during pump operation, and thus extends the service life of the pump and motor.
Application
- Water supply and drainage---Ensures stable water flow and treatment
- HVAC and Cooling tower---Circulate cooling water to keep equipment running and remove heat in cooling towers
- Marine-Ballasting &Bilge---Ensure the stability and safety of the ship
- Booster and pressurization set---Provides constant water pressure, suitable for high-rise buildings and industrial applications that require stable water pressure.
- Irrigation and agriculture---Provide sufficient water resources for farmland to support crop growth
- Food and chemical industry(with stainless steel material)---Stainless steel end suction centrifugal pumps resist corrosion and keep the media pure
