Clarke PLD...good under pressure!

PLD (Pressure Limiting Driver) UL-FM EPA

Clarke's variable speed Pressure Limiting Driver (PLD) prevents sprinkler system over-pressure and eliminates excessive discharge of water from pressure relief valves. The variable speed technology maintains system pressure below the system limits by regulating the speed of the diesel pump driver. The PLD eliminates the need for pressure relief valves, conserves water, and avoids the high cost of break tank installations. Clarke received a U.S.Patent for its PLD technology in 2007.

And Clarke's PLD conforms to the NFPA 20 standards established in 2003.
