3,4,5 and 10 Frame Triplex

Features

CAT 3, 4, 5 and 10 Frame Triplex Piston Pumps are used for mid range industrial applications where extreme durability and high suction capability is required.

 

3 Frame

Superior Design

  • Triplex Uniflow design provides continuous forward liquid flow for smooth operation.

  • Wetted cups and floating pistons are lubricated and cooled by pumped liquid for long cup life.

  • Mechanically actuated inlet valves give strong lift and easy prime.

  • 304 stainless steel discharge valves for wear resistance.

  • Oil bath crankcase assures optimum lubrication.

  • 100% wetted seal design allows pumped liquid to cool and lubricate for longer life.

Quality Materials

  • Cylinder and sleeve wear surfaces are hard chrome plated 304 stainless steel for maximum durability and abrasion resistance.

  • Chrome plated, brass manifolds and optional stainless steel manifolds are strong and corrosion resistant.

  • Special high strength TNM connecting rods offer superior bearing quality strength.

  • Chrome-moly crankshaft gives unmatched strength and surface hardness.

  • Oversized crankshaft bearings with greater loading capacity mean longer bearing life.

Easy Maintenance

  • Stepped stainless steel piston rod with chrome-plated, stainless steel sleeve allows easy replacement from front of pump.

  • All wet-end wear parts are easily services without entering crankcase, requiring less time and effort.

  • Wear parts are available in convenient kits.
