Model 2530 Shown
Superior Design
l
Triplex plunger design gives smoother liquid flow.
l
Special epoxy painted crankcase, bearing covers and rear cover with liquid gasket seal provides added moisture protection (2530E Only)
l
Hi-Pressure Seals are completely lubricated and cooled by
the liquid being pumped.
l
Lubricated Lo-Pressure Seals provide double protection against external
leakage.
l
Oil bath crankcase assures optimum lubrication.
l
Close tolerance concentricity of the ceramic plunger maximizes
seal life.
Quality Materials
l
Precision design 3 6SS valves and seats are hardened and polished for
ultimate seating and extended valve life.
l
Brass, 3 6 Stainless Steel or Nickel Aluminum Bronze manifolds are
strong and corrosion resistance.
l
Special concentric, high-density, polished, solid ceramic plungers provide a true wear surface and extended seal life.
l
Specially formulated, CAT PUMP exclusive, Hi-Pressure seals offer
unmatched performance and seal life.
l
Die cast aluminum crankcase provides high strength, minimum weight
and precision tolerance control.
l
Chrome-moly crankshaft gives unmatched strength and surface
hardness.
l
Oversized crankshaft bearings with greater loading capacity mean longer
bearing life.
Easy Maintenance
l
Wet-end is easily serviced without entering crankcase.
l
Interchangeable inlet and discharge valve assemblies.
l
Preset seals require no packing adjustment.
SPE IFI ATIONS
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.

MODEL
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.
