Liquid lubricated, dual mechanical seals require an external source of fluid. A properly selected supply tank system eliminates the need to connect to a distant and sometimes unreliable barrier fluid source. Flowserve offers a complete line of standard reservoirs for a wide range of sealing applications and custom designed supply tank systems based on your specifications.

Liquid-lubricated dual mechanical seals require an external source of fluid. A properly selected circulation system eliminates the need to connect to a distant and sometimes unreliable pressure source and creates barrier fluid flow when the seal cannot induce flow. Flowserve offers a complete line of standard circulators for a wide range of sealing applications and custom designed circulation systems based on your specifications.

Refill the reservoir in operation without pump downtime or venting unwanted gases to atmosphere.

Buffer/Barrier gas panels combine flow monitoring and control elements in a self-contained, easy to use unit.

A piston transmitter is a 'pressure multiplier' which generates barrier pressure for double liquid seals from product pressure. It is used where the pressure in the pump fluctuates, or the inboard seal pressure differential must be limited. Best used for higher pressures above 50 psi (350 kPa). Can be executed with cooling coil, instrumentation, refill pump, standard according TuV but can be made according ASME, total volume: 0.8 a

Seal coolers are used in high temperature applications to reduce the sealing temperature thereby enhancing and increasing the MTBF of the equipment.
