Pump Drives
PEM’s pump drive gearboxes are designed for long life in applications when a high AGMA service factor is needed. PEM’s pump drives are unique in that our units can drive up to 8 pumps from a single or multiple prime movers; electric, hydraulic or diesel. Any input and output configuration can be designed with any mounting and material of construction you may require. We have designed and produced units with as much as 1,200 hp and 250,000 lb-ft of torque.
 
Any gearbox has the option of using our trademarked gear tooth design we call Megagears. The Megagear allows for up to 33% more torque than a gear of the same diameter with a typical tooth design. We can even retrofit our Megagears into your existing box by another manufacturer.
 
Typically our cases are designed with a vertical split rather than a horizontal split across the bearings. A typical gearbox design is calculated to handle customer specifications and then evaluated prior to construction. One method of evaluation is FEA (Finite Element Analysis).  After final assembly every gearbox is given a spin test before it’s shipped to ensure that you will receive a gearbox of the highest caliber

Please note that this information describes what we’ve already designed and built, not what our limitations are. If any of your requirements exceed the ranges specified below, do not hesitate to contact our engineering department.
