All pumps require both a primary pressure regulating device (i.e. regulator, unloader) and a secondary pressure safety relief device (i.e. pop-off valve, safety valve). Failure to install such relief devices could result in personal injury and/or damage to the pump and/or to the system components. We do not assume any liability or responsibility for the operation of a customers high pressure system.
