The RPF Series hydraulic coupling Roots pumps utilize advanced hydraulic driven technology and are quite suitable for applications with high differential pressures. They can be started simultaneously with a backing pump, providing automatic overload protection. The rotors of Roots pumps are non-contacting, enabling high-speed rotation and achieving high pumping speeds with a compact footprint. When combined with a backing pump, these pumps can gain higher vacuum grade, significantly improve pumping performance and shorten pumping times. Through strict clearance control, precision gear construction, and reliable sealing technology, these Roots pumps can offer reliable performance, smooth operation, high efficiency, and low noise, etc.
