For several years, Randax Oy has been a supplier of unique PM motor solutions for its customer Pentair. Randax motors are used for slow-speed Pentair Fairbanks Nijhuis Fish Friendly Pumps and Turbines.
The Pentair branch in Winterswijk (The Netherlands) specializes in designing, producing, and maintaining tailor-made pumps and pump systems. A wide variety of pumps and controls serve multiple markets, including water supply, sewage handling, flood control, hydropower, desalination, agriculture, irrigation, and fire protection.
In 2020, Randax developed a new slow-speed pump motor model to meet Pentair’s high-quality standards and requirements for reliability. The new motor type is flange-mounted, air-cooled, 90 kW power and has a maximum speed of 190 rpm. As usual, Randax tailored all interfaces and connection points to meet the customers’ requirements. The end-user chose the color of the motor and it got a refreshing yellow coating!
In December 2020, the motors were successfully tested at Randax premises in Oulu, Finland. The first two motors have already been installed and commissioned in a pumping station in The Netherlands.
