Crown CR-27DC – Engineered for Demanding Basement Dewatering Applications

The Crown CR-27DC sump pump is built for demanding sub-surface water management. With a rugged 1/2 HP motor, corrosion-resistant components, and automatic operation, this unit is purpose-built for professional-grade basement installations where reliability and performance are essential.

Whether deployed in retrofit or new construction, the CR-27DC is suitable for high-volume dewatering where system uptime and long-term durability are critical. The pump’s efficient design and high flow capacity make it an ideal choice for contractors seeking dependable performance under variable groundwater conditions.

Core Engineering Benefits

• Heavy-Duty 1/2 HP Motor – Capable of sustained high-flow output for rapid water evacuation.
• Corrosion-Resistant Housing – Resilient under extended exposure to moisture and contaminants commonly present in sump pits.
• Integrated Float Switch – Activates automatically based on water level, minimizing intervention and risk of flooding.
• Efficient Electrical Profile – Operates at 115V with reduced amperage draw for energy-conscious system integration.
• Thermal Overload Protection – Prevents premature motor failure under excessive operating temperatures.

Technical Specifications

• Motor Output: 1/2 HP
• Discharge Rate: Up to 3,000 GPH at optimal lift
• Total Dynamic Head: Rated up to 25 ft
• Power Supply: 115 VAC
• Unit Weight: 30 lbs

Installation Considerations

Installation should be performed by a licensed contractor to ensure code compliance and functional reliability. The CR-27DC includes standard discharge fittings and is compatible with most 1-1/2" sump basin piping configurations. Tools required for install typically include:

• Pipe wrench and/or channel locks
• Schedule 40 PVC pipe and fittings
• PVC primer and cement
• Pipe level and thread sealant tape

Proper basin preparation and float clearance must be verified during install. Electrical connections should be made in accordance with NEC standards and protected by a GFCI outlet.

Contractor-Focused Advantages

The CR-27DC is optimized for use in residential and light commercial job sites. Its compact footprint supports tight-space installs, while the motor’s high-efficiency windings and overcurrent protection reduce service callbacks. Internal float switch calibration ensures consistent operation under variable load conditions.

Key Operational Features

• Sealed Construction – Protects motor and electronics from sump pit contaminants.
• Space-Efficient Profile – Facilitates installation in confined or retrofit spaces.
• Reliable Start/Stop Logic – Automatic float system supports unattended operation without false cycling.
• Quiet Operating Mode – Pumping noise is reduced via precision impeller design and motor insulation.
• Integrated Safety Systems – Includes built-in thermal cutoff to prevent motor burnout under adverse conditions.

Specification-Driven Selection

For contractors requiring a sump pump with verified performance in flooded basements, crawlspaces, or drainage basins, the Crown CR-27DC delivers field-proven reliability. Its performance profile supports high-throughput applications with reduced installation complexity.
