Heavy Duty Compensated Servo Pulser

Slick-HD is the second generation of Rime’s patented rotary shear valve servo pulser. It builds on the proven success of our first generation Slick™ servo pulser and adds significant improvements in reliability across the entire operating regime. 

Slick-HD features a rotary shear servo valve that provides exceptional performance in high solids and high lcm environments. It minimizes the pressure loss through the servo module, thus allowing greater forces to be imparted to the main valve assembly. This helps create more reliable, sharper and cleaner pulses than can be achieved with other types of servo pulsers. The wiping and cutting action of the rotary shear valve clears away any compacted debris and ensures unobstructed flow through the system in the most challenging and contaminated environments. 

Slick-HD decouples the hydrostatically compensated section of the servo pulser from the pulser driver module with a high torque magnetic coupling assembly. This eliminates failures of the motor and driver module caused by corrosion, fluid or gas invasion and erosion while also reducing frictional losses in the drive train. 

Slick-HD is available in both dual port or quad port versions. Dual port provides the highest level of lcm capability while quad port offers the ability to achieve faster pulse widths. Slick-HD is available with many connector and interface options including kintec, lemo and mdm. 

The combination of the rotary shear valve, magnetic coupling drive mechanism and robust control electronics enables Slick-HD to have exceptional performance in deep, hot and hostile environments while maintaining the best combination of low operating cost, high reliability and exceptional functionality.
