Description
DEENPU supplies a complete range of replacement parts fully interchangeable with Cameron Type UM BOP blowout preventers. The Cameron UM BOP is a lightweight ram-type BOP designed for easy maintenance and long life. The UM complements the U preventer line with interchangeable bonnets that can be installed on any comparable size Type U BOP.
The UM features a patented, reversible piston that converts standard pipe ram operating pistons to a larger piston designed for shearing — reducing weight and length while eliminating external plumbing. The same bonnet is used for both shear and pipe rams, and the internal shear booster can be reversed to act as a stroke-limiting device.
All DEENPU replacement parts are dimensionally and functionally interchangeable with genuine Cameron UM BOP components. Part numbers are listed below for cross-reference.
