Horizontal Centrifugal Pump, KTZ Type Cooling Tower Pump
The KTZ cooling tower pump is a single-stage single-suction centrifugal pump used to transfer clean water or liquids similar to clear water. It can be used in conjunction with an HVAC system, or used in a central air conditioning cooling system, waterworks supply, and other applications. The noise level is lower than that of an ordinary Y-type motor.
Medium temperature: less than 80℃
Ambient temperature: less than 40℃
Working pressure is divided into two levels: 1.0MPa and 1.6MPa (Please specify when ordering to ensure reliable use)
1. Pump cover
2. Water slinger
3. Mechanical seal
4. Motor with a lengthened shaft
5. Impeller nut
6. Seal ring
7. Impeller
8. Pump casing
9. Base
- Direct-connect structure facilitates installation, maintenance and repair: During repair, the pump body, inlet, and outlet pipes do not need to move. Just move the motor, and impeller and other parts can be removed for repair.
- To balance the axial force of the pump, a balance hole structure is utilized.
- A wear-resistant mechanical seal is utilized to ensure a stable, reliable operation and long service life.
- Precise casting impeller, high strength shaft and matching imported bearing.
- To guarantee the pump high quality, the impeller material is divided into a wear resistant cast iron and a cast copper. Customers can choose which one they would like based on their specific usage conditions.
