ELECTRIC HORSEPOWER REQUIREMENTS
MODEL
271, 277
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.
