The Nordstrom 400-D Hand Gun is rated at 10,000 – 11,000 psi (690-759 bar) and includes may features for meeting the exact demands of replacing sealant in lubricated valves.
Due to the “built-in” safety features, the 400-D Hand Gun provides maximum safety both to the user and the gun itself. The hydraulic system of the gun is equipped with an interanl relief valve to protect the operator if pumping continues after the gun is depleted fo sealant. A pressure gauge indicates the point at which sufficient sealant pressure has been developed within the valve.
In designing the 400-D Hand Gun, engineers concentrated on greatly simplifying manintenance and repair procedures. In most cases, the gun can be easily maintained and repaired by valve service personnel, without requiring factory service.
