The Sanjack hydraulic ram BOP is mainly used in workover and drilling operations with varied technical requirements.

With a BOP body, side outlet, ram body, and other pressure bearing parts crafted from defect-free forged metal, and an oval-shaped inner chamber to reduce stress concentration and improve its sealing performance, this BOP can efficiently prevent an oil well blowout.

The double ram BOP can be equipped with different types of rams, such as pipe ram, blind ram, shear ram or variable diameter ram, to meet different applications.

The ram seal is a float type, which will decrease the resistance and abrasion of the rubber core.

The service life is greatly prolonged. Its anti-H2S performance conforms to NACE MR 0175 standard.
