Plastic lined Kalsi Seals reduce breakout torque at 1,000 psi

Some large diameter equipment, such as hydraulic swivels and passive rotating control devices (RCDs), has limited available torque to initiate rotation. When limited available torque is combined with higher pressure sealing requirements, rotary seal breakout torque can exceed available torque. Kalsi Engineering has developed and tested two technologies that significantly reduce the breakout torque of […]
