Реле перепада давления для погружных регенеративных турбинных насосов серии RX

The Ebsray® Differential Pressure Switch (DPS) ensures adequate cooling and lubrication flow through for RX10 Series pumpset internals. The overall pumping system's differential pressure must be maintained above a preset minimum level. The DPS signals the pump controller if the minimum ΔP:

a) falls below the preset minimum level during operation,
b) is not developed within the preset maximum time after startup

The DPS includes Ex certifications to ATEX, ANZE and UL for Class 1 Zone 1.
