Grinder Pump 1hp "KPCG-21" High Head

The KEEN GRINDER PUMP KPCG series progressive cavity grinder pumps feature the best performance (high pressure and flow), combined with unique industry leading design features and materials of construction. This provides the most reliable, longest service life progressive cavity pump in the market. The KPCG grinder pump can move wastewater through miles of piping network and is designed for use in pressure sewer applications.

Dependable, consistent flow rates, regardless of varying system operating pressures and vertical elevation differences makes the KEEN KPCG grinder pump the pump of choice. Designed to deliver 8.5 gpm at 180’ operating heads, the KPCG grinder pump can produce even higher operating heads at reduced flow rates.

• Unique rotor and stator geometry design
• Scratch resistant, steel hardened, chrome finish rotor
• Wear resistant, special compound stator  
• Best wear and chemical resistant stator
• Hardened stainless steel grinder assembly
• 3-Bearing shaft support
• Dual silicon carbide shaft seals
• Strong torque 1 HP motor
• Potted cord cap assembly

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.
2. Internal Start Kit
   Start / Run capacitor with relay securely positioned in dry compartment. Rubber compression grommet for wire leads to motor prevents oil from entering chamber.
   4 bolts quickly removes cord cap for easy servicing.
3. 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.
4. Strong Motor
   High torque for powerful and reliable pump operation. Pressed stator securely holds motor and efficiently transfers heat. Class F insulation with overload protection in oil filled chamber for cool operation and long motor life.
5. 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.
6. Double Mechanical Seal Protection
   Dual silicon carbide mechanical shaft seals provide twice the moisture 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.
7. Non-Overloading Hydraulic Design
   The 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. Proven Grinder Assembly
   Hardened (Rockwell 56-60) stainless steel grinder assembly has 30+ years proven field experience. The reversible grinder ring and grinder impeller effectively reduces solids into a fine slurry, easily passable in a piping system without concerns of clogging. Highly efficient 7,400 cuts per second.
9. Easy Piping Connection
   Removable 1-1/4” NPT connection flange for simple and easy connection to discharge piping.
10. Accessories Included
    Stainless steel lifting handle is included with the pump.
