Triplex plunger design provides smoother liquid flow.
Oil bath crankcase assures optimum lubrication.
Close tolerance concentricity of the ceramic plunger maximizes
seal life.
Standard Models: Lo-Pressure Seals and V-Packings are completely
lubricated and cooled by the liquid being pumped.
Flushed K Models:
Special ported inlet manifold permits an external
flush liquid providing cooling for hi-temp liquids and lubrication for low
lubricity liquids.

COMMON SPECIFICATIONS
Precision design 316 stainless steel valves and seats are hardened
and polished for ultimate seating and extended valve life.
316 SSL block-style manifolds for strength 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.
Optional Cast Iron crankcase for hazardous environments.
Chrome-moly crankshaft gives unmatched strength and surface
hardness.

FLOW
Oversized crankshaft bearings mean longer bearing life.
Easy Maintenance
Wet-end is easily serviced without entering crankcase, requiring less
time and effort.
Inlet and discharge valve assemblies interchange for easier
maintenance.
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.
Dipstick offers top access for easy oil
level check.
Oversized crankshaft bearings provide extended bearing life and pump performance.
Chrome-moly crankshaft provides
unmatched strength and surface hardness for long life.
Matched oversized high strength connecting rods are noted for superior tensile
strength and bearing quality.
Special stainless steel high strength
plunger rods for high load bearing and
longevity.
The stainless steel barrier slinger
provides back-up protection for the
crankcase seal, keeping pumped liquids
out of the crankcase.
8 Special concentric, high-density, polished,
solid ceramic plungers provide a true
wear surface and extended seal life.
9 Manifolds are 316 SSL or Duplex blockstyle for long-term, continuous-duty and
corrosion resistance.
10 Standard Models: Lo-Pressure Seals
and V-Packings are completely lubricated
and cooled by the liquids being pumped.

Lenntech
10 Optional special ported Flushed Inlet
Manifold permits external flush for
lubricating and cooling seals when pumping liquids such as DI water, Hi-Temp or
low lubricity.
11 316 stainless steel valves, seats and
springs provide corrosion-resistance,
ultimate seating and extended life.
12 Specially formulated, CAT PUMP exclusive,
V-Packings offer unmatched performance
and seal life.
13 Crossheads are 360˚ supported for
uncompromising alignment.
