Features and Benefits

1. Triple Sealed Cable Entrance
   Stainless steel strain relief cord grip with compression grommet protects outer cord jacket. Epoxy filled inner cord cap with individually soldered wires provide anti-wicking moisture protection to the motor even if power cable is cut or damaged. 40’ U/L power & control cords.
2. 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.
3. Strong Motor
   Powerful high torque motor for reliable pump operation.
   208 / 230 volt, 1-phase
   208 / 230 / 460 volt, 3-phase
   Pressed stator securely holds motor and efficiently transfers heat. Class F insulation with overload protection in air filled chamber for cool operation and long motor life.
4. Solid Bearing Support
   Motor / Pump shaft securely held with upper and lower ball bearings rated for long 50,000 hour B-10 life.
5. 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 handles sand, grit and abrasive materials.
6. Moisture Detection
   Seal leak probe signals alarm in control panel for scheduled maintenance.
7. High Efficiency Hydraulic Design
   Highly efficient enclosed 2 vane impeller easily passes
   3” diameter solids without blockage. The strong ductile iron impeller features backside pump out vanes, keeping the lower mechanical seal clean and pressure compensated for longer life. Dynamically balanced for smooth quiet operation and long bearing life.
8. 4” Discharge Flange
   4” horizontal, 125# ANSI discharge flange.
   Industry standard, 8-bolt pattern.
9. High Performance Wear Ring
   Assists impeller in providing higher performance efficiencies and prevention of recirculation 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.
