ELECTRIC HORSEPOWER REQUIREMENTS
FLOW
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.
