Quad Base Classic Pump
Basic pump assembly has an air supply bypass plate for control via on/off air supply to the pump base inlet port. Includes air pressure gauge and vacuum gauge.
NR = Non-Return Valve is installed between the base and the primary ejector cavity and is used to prevent cross flow between two vacuum pumps connected to the same system. A quick release option should always be considered whenever the NR option is specified since the vacuum can no longer dissipate through the ejector nozzle. Do not use NR to trap vacuum in a system where the pumps are off and the load holding safety is involved.
