Features and Benefits
Standard Features and Benefits
- Universal design facilitates the operational flexibility to drop multiple styles of darts or wiper balls
- Large 6.625” cage ID prevents “wadding” or deformation of dart fins and mitigates fluid bypass and displacement volume discrepancies to prevent costly remedial cementing operations
- Industry-exclusive LED tattle-tale enables visual and audible confirmation of dart or wiper ball release to eliminate personnel manually confirming from the rig floor
- Industry-exclusive inspection port on each chamber allows for viewing inside the cement head, improving operational efficiencies by ensuring proper load out and release of darts and wiper balls
- Proprietary Quik-Lock™ connection provides the industry’s fastest dart and wiper ball reloads to improve operational efficiency
- High-pressure swivel facilitates high RPMs and long-duration rotation while conditioning and cementing to improve quality of cement job
- Swivel can be removed from assembly when pumping cement through the top-drive to reduce overall length for various applications
- Industry-exclusive ball droppers provide the ability to drop two liner setting balls, up to 3” in diameter, without adding additional chambers to the cement head
- Administrative CE marking available for required environments
Optional wireless features and benefits
- Includes cementing plug valve, pin pullers, ball droppers and wireless isolation valves that eliminate hydraulic umbilical lines to reduce the number of riding belt trips above the rig floor
- Fully-wireless automation system eliminates the requirement to pause pumping, reciprocating, or rotating during cementing operations to enhance operational efficiencies
- Manual backup on all remote-operated features ensures redundancy and risk-free operation
- Continuous wireless link monitoring and radio signal filtering blocks Wi-Fi® and other wireless transmission interference for increased reliability
- ATEX Zone 1, IECEx, and UL Class I, Division 2 safety certifications available for required environments
