Quality Materials:

• Precision design 304 stainless steel valves and seats are hardened and polished for ultimate seating & extended valve life.
• Brass manifold is strong and corrosion resistant.
• Special concentric, high-density, polished, solid ceramic plungers provide a true wear surface and extended seal life.
• Specially formulated, Hi-Pressure Seals offer unmatched performance & seal life.
• Die cast aluminum crankcase provides high strength, minimum weight and precision tolerance control.
• Chrome crankshaft gives unmatched strength and surface hardness.
• Oversized crankshaft bearings with greater 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.
