Electric (triplex)

The electric motor driven module is the primary source for generating the hydraulic energy which is stored in the accumulators to operate the BOP functions.  The pumps are offered in a variety of options to incorporate them into the complete BOP control system.  The electric driven pump modules manufactured by CAD Control Systems are designed for operation in hazardous locations where the presence of explosive gases are anticipated and include automatic electric explosion proof motor starters and explosion proof pressure switches as required.    
 

Pneumatic

Pneumatic operated pump modules are used to provide high pressure fluid energy to charge the accumulators and operate the BOP stack functions.  They are used in conjunction with electric pump modules as an option to provide/meet the requirement for multiple power sources for BOP control systems.  Pneumatic pump modules are supplied in various options and configurations to meet specific system requirements.
