Darley to Introduce Silent Pak Pump at FDIC

The new PSD “Silent Pak” pump allows for a 1,500 gpm NFPA-rated pump without a pump transmission. After working closely with Chelsea and Allison for months, on December 1, 2011, Darley received approval for a 1,500-gpm rating from Chelsea when using their Model 870XAFJP-B5XV series PTO with a 200 percent  ratio and an Allison EVS 3000 Series transmission. The engine speed needed is only 2,049 rpm, so it can be matched with most engines on the market capable of producing at least 225 net horsepower. The Allison transmission must be ordered with the 1:00 PTO provision, but the pump can run off the 8:00 or 1:00 position.

This new pump PSD “Silent Pak” is:

  • Quiet – No transmission to generate pump noise
  • Compact – Pump weighs only 225 pounds
  • Economical – Priced at a fraction of the cost of conventional splitshaft midship pumps
