2 Features and Benefits 1. Watertight Cable Entrance Heavy-duty molded compression grommet protects outer cord jacket. *Explosion-proof cable entrance option provides agencyapproved, watertight strain relief cord grips with compression grommets to protect 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. K4RH(X) 1 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 35 cast iron components Strong Motor Powerful high-torque motor for reliable pump operation. Pressed stator securely holds motor and efficiently transfers heat to cast housing. Class F insulation with overload protection in oil-filled chamber for cool operation and long motor life. 3a. Oil Proprietary Keen oil ensures industry-low operating temperatures Bearing Support Motor / Pump shaft securely held with upper and lower ball bearing plus additional sleeve bearing in lower seal chamber. Long 50,000 hour B-10 bearing 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 handle sand, grit and abrasive materials. 6. Moisture Detection Seal leak probe signals alarm in control panel for scheduled maintenance Non-Overloading Hydraulic Design Recessed centrifugal impeller allows 100% performance curve operation from shut-off to maximum flow without damage to the pump or system. The recessed, vortex impeller is out of the passageway of fluid flow, eliminating concerns of blockage or wear Solids-Handling Clear, unobstructed passageway provides reliable movement of solids. 9.
