Stackpole International is the leading ‘black box’ oil pump supplier for engines and transmissions in North America. In addition, we continue to lead the optimization and commercialization of variable displacement oil pumps, which we pioneered 18 years ago.

We take a systems approach in supplying our powertrain solutions. In addition to producing precision gear and vane pumps for engines and transmissions, we provide mechanical vacuum pumps and balance shaft modules. We also produce electrically driven auxiliary pumps.
