Glycol injection failures at critical well control moments carry significant operational and safety consequences. The RCP Glycol Injection Unit uses an air-operated double-head dual-acting (DHDA) pump to deliver infinitely variable high-pressure liquid flow up to 21,596 psi from standard rig air pressure.
The DHDA pump stalls at a predetermined pressure and holds it without consuming power or generating heat — providing a proven low-maintenance solution for continuous or emergency injection applications in hazardous offshore environments.
