Seal Support Systems - Piston Transmitters

BRAND: Flowserve

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
