Description
Our M-300 electric drivehead employs the highly efficient and extremely safe hydrodynamic braking system. Our dual motor system design is used in high-horsepower applications in conjunction with our high-volume/high-lift progressive cavity (PC) pumps. As part of our commitment to safety, all our direct drives have a fully enclosed and hinged belt guard. Each drive is tested and inspected to meet our quality requirements.
