Energy-Efficient Design: The pump features an energy-efficient design that maximizes performance while minimizing power consumption. Professional buyers value pumps that contribute to sustainable operations, balancing high efficiency with cost-effectiveness.
Precision Flow Control: Equipped with precision flow control mechanisms, the pump ensures accurate and stable water flow rates, enhancing desalination output quality. Buyers prioritize pumps that offer precise control and reliability, ensuring consistent and high-quality desalinated water.
User-Friendly Maintenance: Designed for easy access and maintenance, the pump simplifies routine checks and repairs. Professional buyers appreciate pumps that offer user-friendly features, enabling seamless integration into desalination systems and reducing downtime.

This advanced pump works best with a thin, clear liquid that is both non-flammable and non-explosive. It is important that the liquid is free from any solid particles or fibers, ensuring seamless operation.
Liquid temperature
The pump is versatile and can operate under a range of temperatures: The normal temperature type is suitable for -15 ºC to +70 ºC, while the hot water type can handle from -15 ºC up to a robust +120 ºC.
The maximum environmental temperature for optimal performance is +40 ºC.
Designed for altitudes reaching up to 1000 meters.

2,In this setup, the CDLF pump serves as the initial feed pump, while the CDH pump is specifically engineered for high-pressure tasks. This documentation solely features technical details regarding the high-pressure pump's capabilities.
3,The CDH pump is a specialized non-self-suction, vertical multi-stage centrifugal model. A standard motor, directly linked through a coupling, drives the pump shaft from the pump head. The pressure cylinder along with overcurrent components is securely fastened between the pump head and the inlet/outlet sections using tension rod bolts. The inlet and outlet are aligned at the base, with the pump's rotation opposing that of the feed pump. This reverse flow channel configuration ensures that the direction of liquid flow is opposite, thus enhancing reliability by having the pressure cylinder and mechanical seal withstand only the feed pump's outlet pressure.
