Effectively safeguard your electrical submersible pump (ESP) and progressing cavity pump (PCP) equipment from costly damage or blockage caused by descending solids, while unlocking additional revenue by releasing unrestricted natural flow to surface when the pump is not in use.


Delivering reliable pump protection while maximizing system output

Sand, coal fines, and other suspended solids descending into ESPs and PCPs following shutdown can result in a complete loss of production, with the pump unable to restart due to blockage along with risk of equipment damage. Systems then require pulling in order to be released and resume production. The associated downtime and cost of deferred production while awaiting hoist attendance and time needed to repair, pull, clean, and re-run the entire completion adds significant cost. In addition, artificially lifted wells with the capability to free flow to surface experience restriction, pressure drops, and pump damage as fluid passes through the nonoperational pump, resulting in loss of production and risk of damage.

Zenith Tubing Drain Valves (TDVs) are installed above the pump to deliver reliable protection, preventing sand and debris from descending into the pump on shutdown. Annular flow ports automatically and instantly open when the pump is switched off, allowing the tubing column to drain directly into the annulus, protecting against damage. Any natural flow to surface is rerouted around the nonoperational pump. On pump startup, annular ports pilot to the closed position. Production flows to the tubing with the unique Zenith valve mechanism preventing recirculation, a common issue for alternative valves.


A reliable, designed-for-purpose solids management system

Addressing the failings of alternative ESP and PCP system valves, with immediate auto-closure, easy-open prevention of recirculation and ability to backflush or bull head through the valve, Zenith TDVs offer an efficient solution for comprehensive protection of artificial lift pumping systems.
