M-150 Electric Driveheads

We provide a complete line of electric driveheads for all your production needs.

Our M-150 electric drivehead is part of the M-Series of direct drives, which employs the efficient hydronamic braking system. The dual motor system design is used in medium- to 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.
