Features:

• Triplex design delivers high efficiency and low pulsation.
• Durable dual V-Packings are lubricated and cooled by pumped liquid.
• Pre-set Lo-Pressure seals provide secondary protection against external leaks and no packing adjustments are required.
• Special high-density, polished, concentric plungers provide a true wear surface and extended seal life.
• Specially formulated Seals and V-Packings offer unmatched performance and extended life.
• Interchangeable inlet and discharge valves for easy servicing.
• Wet-end easily serviced without entering crankcase.
• Manifolds are high strength forged brass or stainless steel for long-term, continuous duty.
• 100% wet seal design adds to service life by allowing pumped liquids to cool and lubricate on both sides of seals.
• Stainless steel valves, seats and springs provide corrosion-resistance, ultimate seating and extended life.

Parts List: An extensive parts list with part numbers, descriptions, quantities, and material codes for both models is included in the full PDF.
