FEATURES
Superior Design
●
●
●
●
●
●
Triplex plunger design provides smoother liquid flow.
V-Packings are completely lubricated and cooled by the liquid being
pumped.
Special ported manifold permits an external flush liquid providing cooling for hi-temp liquids and lubrication for low lubricity liquids.
Lubricated Lo-Pressure Seals provide double protection against
external leakage.
Oil bath crankcase assures optimum lubrication.
Close tolerance concentricity of the ceramic plunger offers perfect
alignment and maximizes seal life.
Quality Materials
●
●
●
●
●
●
●
Precision design 304 and 316 Stainless steel valves and seats are
hardened and polished for ultimate seating and extended valve life.
Bronze or Duplex Stainless Steel manifolds are strong and corrosion
resistance.
Special concentric, high-density, polished, solid ceramic plungers
provide a true wear surface and extended seal life.
Specially formulated, CAT PUMP exclusive, V-Packings offer
unmatched performance and seal life.
Die cast aluminum crankcase provides high strength, minimum
weight and precision tolerance control.
Chrome-moly crankshaft gives unmatched strength and surface
hardness.
Oversized crankshaft bearings with greater loading capacity mean
longer bearing life.
SPECIFICATIONS
●
●
Wet-end is easily serviced without entering crankcase, requiring less
time and effort.
Inlet and discharge valve assemblies interchange for easier maintenance
without disturbing piping.
Preset packings mean no packing gland adjustment is necessary,
reducing maintenance costs.
WARNING
All systems require both a primary pressure regulating device (i.e., regulator, unloader) and
a secondary pressure safety relief device (i.e., pop-off valve, safety valve). Failure to
install such relief devices could result in personal injury or damage to the pump or to
system components. CAT PUMPS does not assume any liability or responsibility for the
operation of a customer’s high pressure system.

Die cast aluminum crankcase means
high strength, lightweight, and excellent
tolerance control.
Oversized crankshaft bearings provide extended bearing life and pump performance.
Chrome-moly crankshaft provides
unmatched strength and surface hardness for long life.
Matched oversized TNM connecting
rods noted for superior tensile strength
and bearing quality.
Special stainless steel plunger rods with
high strength crossheads for longevity
and corrosion resistance.
6
The stainless steel slinger provides
back-up protection for the crankcase
seal, keeping pumped liquids out of the
crankcase.
7
Special concentric, high-density, polished,
solid ceramic plungers provide a true wear
surface and extended seal life.
Manifolds are a high tensile strength
bronze or Duplex stainless steel for long
term, continuous duty and corrosion
resistance.
100% wet seal design adds to service life
by allowing pumped liquids to cool and
lubricate on both sides.
8
9
10 Stainless steel valves, seats and springs
provide corrosion-resistance, ultimate
seating and extended life.
11 Specially formulated, CAT PUMP exclusive, V-Packings offer unmatched
performance and seal life.
12 Crossheads are 360° supported for
uncompromising alignment.
13 Optional special ported Flushed Manifold
permits external flush for lubricating and
cooling seals when pumping liquids such
as DI water, Hi-Temp or low lubricity.
