ELECTRIC HORSEPOWER REQUIREMENTS
MO EL
2510
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 Accessory Data sheet. CAUTIONS and WARNINGS can also be
viewed online at www.catpumps.com/cautions-warnings or can be requested directly
from CAT PUMPS.

100% wet seal design adds to service life
by allowing pumped liquids to cool and
lubricate on both sides of seals.
Stainless steel valves, seats and springs
provide corrosion-resistance, ultimate
