Jabsco 50880-1100 Marine Filterless Shower Drain and Bilge Pump 24V 4.2 GPM

The Jabsco 50880-1100 is a self-priming, single-diaphragm marine pump designed for bilge pumping, shower drain, and sink drain applications aboard boats and vessels running a 24V DC electrical system. Its filterless design and robust joker valve construction make it virtually impossible to block, dramatically simplifying routine maintenance.

Key Features:

• Flow Rate: Up to 4.2 GPM (16 litres/minute) open flow output
• Self-Priming: Self-primes from dry up to 10 ft (3 m) of vertical lift
• Filterless Design: No strainer required — reduces clogging and maintenance
• Extended Dry-Run Capability: Single-diaphragm design tolerates extended dry running without damage
• Quiet Operation: Low-RPM pump head runs significantly quieter than comparable models
• Multi-Positional Ports: 3/4 in. (19 mm) ID hose barb ports rotate for flexible installation in tight spaces
• Maximum Head: Recommended total head up to 6 m (19.7 ft)
• Electrical: 24V DC, 2.5A maximum current draw, 5A fuse
• Duty Cycle: Rated for up to 30 minutes of continuous operation
