Features and Bene�ts

1. Watertight Cable Entrance Heavy-duty molded compression grommet protects outer cord jacket. *Explosion-proof cable entrance option provides agency-approved, 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.

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.

3. 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.

4. 3-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.

7. 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.

8. 3” Solids-Handling Clear, unobstructed passageway provides reliable movement of solids.

9. Standard Flange Connection 4“ Horizontal, Class 125 ANSI discharge flange. Industry standard, 8-bolt pattern.

rpruit Line rpruit Line rpruit Text Box A Grundfos/YCC 4" SL (ANSI) to 4" EL Adaptor Flange is Required. This Adaptor Flange will enable the Keen K4RHX100M2-43, 4" ANSI flanged discharge pump to mate with the existing YCC EL Style 4" Base Elbow. The existing YCC EL Style Sealing Flange will attach to the Adaptor Flange that will then be attached to the Keen Pump discharge flange. This Adaptor Flange adds 5.25" (Flg-Flg) to the pump lay length dimension (from discharge flange face to back of pump).
