WS273 XD

Standard Equipment:

Fluid Ends

• Valve-over-valve design simplifies valve, seat, and plungerinstallation
• Full line of 1502 discharge flanges – male, female, and blank
• Log-style suction manifold
• Grooveless valve stop,grooveless design eliminates stress risers present with agrooved valve stop design
• Plungers with advanced surface technology
• Premium plunger packing
• Polypak seals for more reliable sealing at suction cover anddischarge flanges
• Fluid end components designed to maximize interchangeabilityacross our fluid end line and with industry standard fluid ends

Stainless Steel Options

• All XD Geometric benefits
• Improved corrosion resistance, particularly in recycled water applications
• Improved resistance to stress corrosion cracking
• Optimized autofrettage parameters specifically for stainless steel material

Power Ends

• Reverse helical pinion and bull gear design – great reliability
• Fully welded structure with additional internal supports
• Two-piece stay rod design – pretensioned stay rod lowerscyclic loading and fatigue stress
• Nose plate-to-frame design includes a dovetail interlockingdesign, which increases the structural strength
• Forged or fabricated bull gears – no cast material
• Forged crankshaft – one piece
