Xylem 20SA 800 GPH Automatic Bilge Pump 12V

The Xylem 20SA is an 800 GPH automatic bilge pump that uses electronic sensing technology to eliminate the need for a traditional float switch. This fully submersible marine bilge pump features run-dry protection, backflow prevention, built-in thermal cut-off, and CE/ISO 8849 certification with marine-grade wiring.

Automatic Electronic Sensing Operation:

The pump operates on a timed cycle, checking for water every 2.5 minutes by running for approximately one second to sense for water presence through impeller resistance. If water is detected, the pump will sense the resistance against the impeller and continue running until all water is removed. Water levels are maintained between 1/8" and 3/8", providing superior bilge management without a float switch.

Key Features:

• Compact dimensions: 4.7" high x 2.9" wide x 2.5" deep (not including discharge port)
• 12V DC operation with 3.4 amps at 12V, 4.3 amps at 13.6V
• 3/4" hose barb connection for standard marine hose
• Built-in thermal cut-off protection for pump and vessel safety
• Integrated backflow prevention check valve
• Easy-clean strainer with snap-lock design on pump base
• Discharge port fittings can be configured as straight, 45°, or 90° angle
• Hidden air vents under strainer tabs prevent airlocking in challenging installations
• Durable construction with ABS thermoplastic housing and stainless steel shaft

The 20SA replaces the discontinued Rule 20RS bilge pump and maintains the same base footprint for easy upgrades. This pump achieves rated performance at 12 volts versus the previous 13.6-volt requirement, delivering higher flow with better efficiency. Recommended fuse size: 7.5 amp.
