Every NLB high-pressure pump unit is equipped with a rupture disc to relieve system pressure in the event of a spike above the unit’s maximum operating pressure. The replaceable discs, held in a rupture disc assembly, are available with pressure ratings from 2,000 psi to 40,000 psi (140 to 2,800 bar).
Rupture disc assemblies should always be used with a primary pressure relief valve or by-pass valve. These can be found under the Pump & System Components tab in the navigation.
