Caleffi 548007A Hydraulic Separator, 1-1/4 in, FNPT Union, 150 psi Working, 32 to 210 deg F, Steel

The Caleffi 548 and NA548 series hydraulic separator creates a zone with a low pressure loss, which enables connected primary and secondary circuits to be hydraulically independent of each other; the flow in one circuit does not create or interrupt flow in another. Hydraulically decoupling primary and secondary circuits eliminates pump conflict. This device includes an automatic high-capacity air vent with service valve to discharge accumulated air within the circuits.
