• Durable dual V-Packings are lubricated and cooled by
pumped liquid.
• Pre-set Lo-Pressure Seals provide secondary protection
against external leaks and require no packing adjustment.
• Special high-density, polished, concetric plungers provide
a true wear surface and extended seal life.
• Specially formulated Seals and V-Packings offer unmatched
performance and extended life.
• Wet-end easily serviced without entering crankcase.
Above 130°F call CAT PUMPS for inlet conditions and elastomer recommendations.

ELECTRIC HORSEPOWER REQUIREMENTS
MODEL
All High Pressure Systems require a primary pressure regulating device (i.e. regulator, unloader)
and a secondary pressure relief device (i.e. pop-off valve, relief valve). Failure to install such relief
devices could result in personal injury or damage to pump or property. CAT PUMPS does not
assume any liability or responsibility for the operation of a customer’s high pressure system.
Read all CAUTIONS and WARNINGS before commencing service or operation of any high
pressure system. The CAUTIONS and WARNINGS are included in each service manual and with
each Data sheet. CAUTIONS and WARNINGS can also be viewed online at
www.catpumps.com/cautions-warnings or can be requested directly from CAT PUMPS.
