Details

Bentec completely redeveloped the concept of Mud Pumps. Being equipped with a direct-driven gearbox, an own developed motor, and a state-of-the-art pump housing, there is no need for an internal gear coming with many disadvantages and no more belt tensioning.

Bentec Mud Pumps are reduced to the task they are actually intended for: pump operations.

Bentec Mud Pumps are light weight and have a small footprint. The AC-powered motor is top or rear mounted – suitable for any drilling rig arrangement. The pump is available with 5 000 or 7 500 psi fluid ends, and all its parts that are subject to wear and tear meet API standards and are available worldwide.

A handling crane makes it easy to handle the fluid end components. Furthermore, Bentec uses a patented liner and valve clamping technology to reduce the maintenance time significantly. A quick-change liner and piston system serves for easy maintenance. A special feature of the Bentec MUD PUMP is the side-mounted gear drive.

This design eliminates the need for chain or belt tensioning systems. The two-stage helical gear feeds directly into a forged/welded crankshaft, which is balanced and provides quiet and vibration-reduced operation.

Liner cooling and gear oiler systems are included; a supercharge pump and a noise reduction package can be installed upon request. The Bentec MUD PUMP is the right choice especially when it comes to noise-sensitive environments such offshore or densely populated environments.

Beyond the supply of Mud Pumps, Bentec acts as system supplier. The pumps can be delivered together with a Bentec Power Control System and a Bentec Soft Pump System.
