  • Watertight Cable Entrance
    • Agency-approved, watertight strain relief cord grips with compression grommets protects outer cord jacket. Epoxy-filled inner cord cap provides anti-wicking moisture protection to the motor even if power cable is cut or damaged. 40' UL power & control cords.
  • Modular Pump Design
    • Commonality of parts across the Keen product line minimizes the amount of parts required for servicing. Heavy-duty ASTM A48, Class 30 cast iron components.
  • Strong Motor (U.S. Motor Manufacturer)
    • Powerful high-torque motor for strong pumping.
      • 208/230/460/575 Volt, 3-phase
    • Slip-Fit stator efficiently transfers heat to cast housing. Class H construction with overload protection in oil-filled chamber for cool operation and long motor life. Inverter-duty capable, for VFD / soft start operation.
  • Oil
    • Proprietary oil ensures industry-low operating temperatures.
  • Solid Bearing Support
    • Two-bearing design featuring high load-rated angular contact bearings for 100,000 hour B-10 life.
  • Severe Duty Dual Mechanical Seals
    • Dual silicon carbide mechanical shaft seals provide twice the moisture and grit protection for the motor. Dual seals are housed in a secondary oil-filled seal chamber. Tougher silicon carbide seals better handle sand, grit and abrasive materials. ** Additional bronze labyrinth seal for explosion-proof model.
  • Moisture Detection
    • Seal leak probe signals alarm in control panel for scheduled maintenance.
  • High Efficiency Hydraulic Design
    • Highly efficient enclosed, 2-vane impeller easily passes solids without blockage. Strong, ductile iron impeller features backside pump-out vanes, keeping lower seal clean and pressure-compensated for longer life. Dynamically balanced for smooth, quiet operation and long bearing life.
  • Standard Flange Connection
    • Horizontal, Class 125 ANSI discharge flange.
      • M4VK 4" flange, industry standard 8-bolt pattern
      • M8VK 8" flange, industry standard 8-bolt pattern
      • M12VK 12" flange, industry standard 12-bolt pattern
      • M14VK 14" flange, industry standard 12-bolt pattern
  • High Performance Wear Ring
    • Assists impeller in providing higher performance efficiencies and prevention of re-circulation losses. Bronze ring will not corrode or deteriorate from liquid being pumped. Bronze ring reduces wear to stronger ductile iron impeller in sandy or gritty applications. Easily serviceable and replaceable.

The curves reflect maximum performance characteristics without exceeding full load.
Performance curves are based on actual tests with clear water at 70°F and 1280 feet site elevation.
Operation is recommended in the bounded area with operational point within the curve limit.
