One, Air Conditioning Circulation Pump ISG200-400A 37KW Selection Product Overview:
Air-cooled circulating water pump ISG200-400A, 37KW circulating pump, is a high-efficiency, environmentally friendly vertical centrifugal pump independently researched and developed based on the ISG technology. This series of pumps boasts excellent performance, high reliability, long service life, reasonable structure, and attractive appearance.


Quality ISG80-125 Pipeline Centrifugal Pump Selection Product Features:
1. The pump features a vertical structure with the same inlet and outlet diameters aligned on a single central axis, allowing it to be installed in pipelines like a valve. It boasts a compact and aesthetically pleasing design, occupying minimal floor space and requiring low construction costs. With a protective cover, it can be used outdoors.
2. The impeller is directly mounted on the extended shaft of the motor, featuring a short axial dimension and a compact structure. The pump and motor bearing arrangement is rational, effectively balancing the radial and axial loads generated by the pump's operation. The pump runs smoothly with minimal vibration and low noise.
3. Axial seals are equipped with mechanical seals or a combination of mechanical seals, utilizing imported titanium alloy sealing rings, medium-sized mechanical seals, and hard alloy materials, effectively extending the service life of the mechanical seals.
4. Easy installation and maintenance; no need to dismantle the pipeline system. Simply unscrew the pump coupling flange nuts to remove all rotor components.
5. Pumps can be operated in series or parallel configurations based on the required flow rate and head.
6. Pumps can be installed in either vertical or horizontal orientation as per the requirements of the pipeline layout.

Section 3: Air Conditioning Circulation Pump ISG200-400A 37KW Selection Working Conditions:
1. Suction pressure ≤ 1.0 MPa, or system working pressure of pump system ≤ 1.6 MPa, meaning pump suction pressure + pump head ≤ 1.6 MPa. The static test pressure of the pump is 2.5 MPa. Please specify the system working pressure when placing an order. If the system working pressure of the pump exceeds 1.6 MPa, it should be mentioned separately when ordering to ensure cast steel material is used for the overflow and connection parts of the pump during manufacturing.
2. Environmental temperature < 40°C, relative humidity < 95%.
3. The volume content of solid particles in the conveyed medium does not exceed 0.1% of the unit volume, with particle size less than 0.2mm.
Note: If the medium contains fine particles, please specify at the time of order to allow the manufacturer to use mechanical sealing.
