3 and 5 Frame Triplex

Features

CAT 3 and 5 Frame Triplex Plunger Pumps are used for mid-size industrial applications and are available in a variety of materials to match liquid requirements. Some models also available with built-in gearbox to suit combustion engine drive (marked GB). Other models suitable for vee-belt drive.

 

3 Frame


Superior Design

  • Triplex plunger design delivers smoother liquid flow.

  • Hi-Pressure Seals are completely lubricated and cooled by the liquid being pumped.

  • Inlet and discharge valve assemblies interchange for easier maintenance.

  • Lubricated Lo-Pressure Seal provided double protection against external leakage.

  • Oil bath crankcase assured optimum lubrication.

  • Close tolerance concentricity of the ceramic plunger maximizes seal life.

  • Optional Belt Drive or Motorized versions offer system flexibility.

Quality Materials

  • Special concentric, high-density, polished, solid ceramic plungers provide a true wear surface and extended seal life.

  • Specially formulated, CAT PUMP exclusive, Hi-Pressure Seals 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.

Easy Maintenance

  • Wet-end is easily serviced without entering crankcase, requiring less time and effort.

  • Preset packings mean no packing gland adjustment is necessary, reducing maintenance costs.
