Pressure Compensators

Designed to balance the internal pressure of oil filled subsea equipment and hydraulic systems with the ambient pressure of the surrounding sea water, Tecnadyne’s PCX pressure compensators have been proven in the world’s harshest subsea environments for many years. The PCX pressure compensators are compatible with all common hydraulic oils and are rated for operation to full ocean depth. In fact, a Tecnadyne PCX pressure compensator was used by Woods Hole Oceanographic Institute in a recent expedition to the very bottom of the Mariana's Trench.

Employing a spring loaded rolling diaphragm, made from a high strength fabric reinforced neoprene material, the PCX pressure compensators maintain the internal oil pressure 4-14psi (0.25-1.0 bar) above ambient. In the event of a leak in the customer’s oil filled system, the slightly higher pressure of the internal oil prevents water intrusion, thereby protecting the internal equipment from water damage.

And since the rolling diaphragm of the PCX pressure compensators eliminates all piston and rod seals, leaks are virtually eliminated for the highest reliability. The housings of the PCX pressure compensators are manufactured from hard anodized 6061-T6 aluminum and the spring and all hardware are made from passivated 18-8 stainless steel. Optional housing materials include Type 316 stainless steel and 3Al2.5V titanium.
