2 KW Features and Benefits 1. Watertight Cable Entrance Watertight strain relief with compression grommet protects outer cord jacket. Cable wires individually stranded in epoxy in cord cap assembly provides anti-wicking moisture protection to the motor even if power cable is cut or damaged. 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 Strong Motor Powerful high-torque motor for reliable pump operation. Pressed stator securely holds motor and efficiently transfers heat. Class F construction with overload protection in oil-filled chamber for cool operation and long motor life. 4. Bearing Support Motor / Pump shaft securely held with upper and lower ball bearing 50,000 hour B-10 life. 5. Severe Duty Dual Mechanical Seals Dual shaft seals provide twice the moisture and grit protection for the motor. Inboard seal silicon-carbide with outboard lip seal. Tougher silicon carbide seals better handle sand, grit and abrasive materials High Efficiency Hydraulic Design Highly efficient, single-vane impeller easily passes 2 dia. solids without blockage. Strong ductile iron design features backside pump-out vanes, keeping lower seal clean and pressurecompensated for longer life. Dynamically-balanced for smooth, quiet operation and long bearing life Solids-Handling Clear, unobstructed passageway provides reliable movement of solids. 8. Vertical Discharge Connection 2 NPT vertical discharge. Volute included with support legs. OPTIONAL 3 NPT Reducer E State Route 250 East. Ashland, Ohio fax

6 KW Specifications Pump Model Pump shall be of the submersible centrifugal type, HP KEEN KW Series. The pump shall easily pass 2 diameter solids through the pump end without jamming and exit through the 3 NPT / 2 reducer bushing discharge. Operating Conditions The pump shall have a capacity of GPM at a total head of feet, and shall use a motor rated at HP and 3450 RPM. Pump Impeller Ductile iron, dynamically balanced and keyed on a stainless steel shaft. The impeller shall be of the single-vane type. Pump Housing Construction All components of the pump construction (cord cap, motor housing, seal plate, volute) shall be cast iron, ASTM A-48, Class 30. There shall not be any composite materials used for any pump components. Seals Motor shall be protected by dual mechanical seals. Type 21, seal construction mounted in tandem, shall protect the motor. Both seals shall be silicon / carbide. The seal face shall be lapped to a flatness of one light band. All hardware shall be stainless steel. The elastomer materials shall be nitrile. Motor The pump motor shall be of the submersible type, rated HP, 3450 RPM. The motor shall be for 60 Hz, either 208 or 230 volt, single phase operation. Three-phase operation shall be 208, 230 or 460 volt. Single phase motors shall be of the permanent split capacitor design with an internal start capacitor for high starting torque. Motor operating temperature must not exceed Class B ratings. The stator winding shall be of the open type with Class F insulation. Winding housing shall be filled with a clean, high dielectric oil that lubricates bearings and seals, transferring heat from windings and rotor to the outer cast housing. Air-filled motors which do not have the superior heat dissipating capabilities of oil-filled motors shall not be considered equal. The motor shall have two heavy duty ball bearings to support the pump shaft, taking radial and thrust loadings. Ball bearings shall be designed for a minimum 50,000 hours B-10 life. The stator shall be pressed into the motor housing. The pump shaft shall be of 416 SST, keyed to accept the pump impeller. The motor shall be capable of operating over the full range of the performance curve without overloading. Single phase motors shall have a heat sensor thermostat and overload attached to the top end of the motor windings to stop the motor if the motor winding temperature reaches 200 degrees F. The high temperature shut-off will cause the pump to cease operation, should a control failure cause the pump to run in a dry wet well. The thermostat shall automatically reset when the motor cools to a safe operating temperature. Three-phase motors contain temperature sensors with (2) two wires for attachment to the control box. Power Cord The motor power cord shall be 14 AWG SOW, 20 length. The cable jacket shall be sealed at the motor entrance by means of a rubber compression washer with concentric ribbing. A stainless steel compression fitting shall securely hold the cable jacket and compression grommet in place. 471E State Route 250 East. Ashland, Ohio fax
