DPLLD Transducer Installation
Red Jacket Standard Pumps (DPLLD w/SwiftCheck)

Figure 4. DPLLD Transducer Installation
9. If there is a Stage II vapor recovery device installed in the pressurized piping you must install the SwiftCheck
valve into a Red Jacket leak detector fitting (P/N 038-072) as shown in Figure
5 instead of in the pump’s leak
detector port. Because the DPLLD transducer must be installed downstream from these devices, a monitored
containment sump is required.
There
must
not be a check valve installed between the SwiftCheck valve and the pump
for DPLLD to function properly.
Ensure that the Healy pump is wired according to the manufacturer’s instructions and utilizes isolation relays.
Lubricate the external o-ring on the SwiftCheck valve using mineral oil or other suitable lubricant and thread
the valve into the Red Jacket fitting.
