Pump Models Offered

CRE Plus Multistage Pump
This simplex pump system adjusts motor output based on demand, optimizing energy use and reducing waste. It improves efficiency, lowers costs, and minimizes wear and tear, all while maintaining constant pressure even with fluctuating demand.

CRNE Multistage Pump
The CRNE is a vertical centrifugal pump with an integrated variable frequency drive (VFD) for precise control and energy efficiency. Built with durable materials like stainless steel and titanium, it ensures reliable performance in varying conditions, reducing energy costs and improving efficiency.

MTRE Multistage Pump
Is a high-efficiency, integrated pump with an IE5 motor and frequency converter. It offers up to 102 m³/h flow and 300 meters head, making it ideal for high-pressure applications. With its compact design, motor protection, and sensor integration, the MTRE ensures reliable performance, energy savings, and easy installation.
