Features & Benefits

REBUILDABLE DESIGN & INCREASED DURABILITY

  • New advanced materials on critical internal wear surfaces
  • Enhanced wear resistance and durability extend pump life
  • All internal wear components are replaceable
  • Simple disassembly and reassembly process saves time and money
  • Complete rebuild kit brings the pump back to as-new operating condition

REDUCED MAINTENANCE

  • Back pull-out Type 2 bellows seal design and spacer coupling eliminate the need to disturb piping or pump and motor placement during seal changes
  • Robust axial thrust control bearing reduces premature seal failure due to elevated inlet pressure, starts, stops, and other unique application conditions
  • Rigid structural steel base with milled mounting pads and jacking bolts for ease of field alignment
  • No pulsation dampeners, gear reducers, belt drives, or additional equipment to service and maintain

MODULAR PORT DESIGN

  • 6”, 180° 3000 Series square flange ports standard
  • Weldneck port adapter design allows for multiple interchangeable flange options
  • Common Port Location (CPL) feature allows for installation of lower flow rate pumps when well production decreases without welding or piping modifications

COMPACT FOOTPRINT

  • 11’ unit length on largest pump and motor assembly for significantly smaller foot print than the competition
  • Motor speed operation eliminates the need for gear reducers or belt drives
  • Units include small, rigid formed steel baseplate complete with spacer coupling and coupling guard

LOWER TOTAL COST OF OWNERSHIP & REDUCED MAINTENANCE

  • Smooth flow eliminates the need for pulsation dampeners and/or complex control valves
  • Motor-speed operation eliminates the need for belt drives
  • No check valves or seats to replace
  • No lube oil or oil changes required
  • No belt drives to service and maintain
  • No pulsation dampeners to maintain

SIGNIFICANT SPACE AND WEIGHT SAVINGS

  • Compact design results in a smaller skid and reduced shipping costs
  • Up to 15’ shorter units, allowing smaller buildings or fabricated skid bases
  • No additional cradle supports on longer pumps, which complicate alignment
