GRACO 563965 – Blowout Disc Kit – (6) Aluminum, 2350 PSI, 11/16″, 3/8″ Diameter

GRACO 563965 – Blowout Disc Kit – (6) Aluminum, 2350 PSI, 11/16″, 3/8″ Diameter

Blowout disc package for rupture-to-atmosphere indicators that provide pump protection and visual indication of excessive system pressure. When pressure exceeds the set point, the disc ruptures at a predetermined pressure setting, venting lubricant to the atmosphere and relieving high pressure in the system.

This is a GRACO part number variant of the standard 557436 blowout disc. Discs greater than 2,350 psi have a tolerance of ± 20%, while discs up to 2,350 psi have a tolerance of ± 500 psi. Part of the rupture-to-atmosphere indicator system. Discs must be replaced after each rupture event and the system manually reset. Standard on all GRACO pumps. When pressure reaches predetermined setting, the pressure disc ruptures, venting lubricant into atmosphere and relieving pressure. All pressures have a tolerance of + 500 psi (3.4 MPa, 34.5 bar)
