Features and Benefits
1. 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.
2. Modular Pump Design
1
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 (U.S. Motor Manufacturer)
Powerful high-torque motor for strong pumping.
208/230 Volt, 1-phase
208/230/460 Volt, 3-phase
Slip-Fit stator efficiently transfers heat to cast housing. Class F
construction with overload protection in oil-filled chamber for cool
operation and long motor life.
3a. Oil
2
3
Proprietary Keen oil ensures industry-low operating temperatures.
4
4. Solid 3-Bearing Support
Motor / Pump shaft securely held with upper and lower ball
bearings, plus additional sleeve bearing in lower seal chamber.
Rated for 50,000 hour B-10 life.
5. Severe Duty Dual Mechanical Seals
5
6
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.
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 lower seal clean and
pressure-compensated for longer life. Dynamically balanced for
smooth, quiet operation and long bearing life.
8. Standard Flange Connection
4“ Horizontal, Class 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.
