General introduction

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.

Working conditions

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)

Structure description
  • 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.
