A piston transmitter is a pressure multiplier that generates barrier pressure for dual pressurized liquid seals based on the product pressure
Used where the pressure in the pump fluctuates or the inboard seal pressure differential must be limited
Pressure multiplier options: 1:1.1, 1:1.15, and 1:1.2
Best used for pressures above 3.5 bar (50 psi)
Can be provided with a cooling coil, external heat exchanger, instrumentation, and refill pump
Standards: ASME or PED

Pressure up to 34.4 bar (500 psi)
Temperature up to 93°C (200°F)

Buffer/Barrier gas panels combine flow monitoring and control elements in a self-contained, easy to use unit
Used for unpressurized and pressurized Flowserve gas seals
Buffer panels provide unpressurized dual seals with a gaseous quench to flush inner seal leakage to a collection system
Barrier panels provide dual seals with gaseous barrier pressure set higher than the process pressure. This results in a small amount of gas leakage into the process and zero process leaking to atmosphere
Meets the design criteria of API 682, ASME B31.3, PED
Offers other configurations of control systems ranging from simple standard to complex custom designs
