Engineering Design and Innovation Skill

Improved Useful Life of the Pump Screw

Through engineering design and innovation, W.G. Benjey has developed a process that improves the properties of rebuilt and newly manufactured cement pump screws. These proprietary advancements have resulted in an extended life of the pump screw, while still generating cost savings to the customer over conventionally manufactured pump screws.

We can rebuild your existing dust pump screws or manufacture you a new one of Benjey design. When building new pump screws, we give you the option of selecting your flight pitch to customize a standard design. In addition, we stock some common pump screw sizes for emergencies, and we take calls 24/7 to get you back up and running as quickly as possible.
