Pump shutoff valves automatically shut down the pump in the event of a diaphragm failure. Multiple smaller AODD pumps (1/2” or 1” models) can be protected by a single SPILLSTOP by routing all of their exhausts through a single SPILLSTOP and adding additional shutoff valves for each pump. Also, it is possible to do this with larger AODD pumps, but they may experience a significant reduction in flow due to the restriction added to the pump exhaust.
