Albin 12V Bilge Pumps: Cartridge vs Low-Profile Size Guide
Bilge pumps have more than one performance figure. The large GPH number on the product label is generally an open-flow rating; water travels through a hose with vertical rise and restrictions in a real installation. Albin offers both replaceable-cartridge bilge pumps and lower-profile versions for tight spaces. This chart compares their flow at a three-foot head, outlet sizes and exact model numbers.
Compare the mounting and discharge before buying
Cartridge-style pumpAlbin's standard cartridge design allows motor cartridge service within its compatible pump body. Check the existing base, height and mounting arrangement.
Low-profile pumpA lower-profile layout suits certain shallow bilge spaces. Compare the base footprint and outlet position rather than choosing by GPH alone.
Correct hose connectionThe 500 and 750-GPH models here use ¾-inch hose discharge connections; the 1,100-GPH models use 1⅛-inch outlets. Check the matching hose and clamps.
Flow warning: A nominal 1,100-GPH pump in this range is rated by Albin at 750 GPH with three feet of head. Actual flow also depends on hose length, routing, bends, restrictions and battery voltage. Select a pump according to the vessel's complete dewatering and electrical requirements.

Bilge pump selection questions
Does a 1,100-GPH bilge pump always move 1,100 gallons an hour?
No. The headline rating is measured under a different flow condition. For these models Albin lists 750 GPH at a three-foot head, and longer or more restrictive installations can reduce performance further.
Does the 1,100-GPH pump fit the same hose as the 750-GPH pump?
No. The Albin 500/750-GPH versions listed here have ¾-inch hose outlets, while the 1,100-GPH versions use 1⅛-inch outlets. Choose the hose and discharge plumbing for the exact pump.
Are the low-profile pumps direct replacements for any cartridge pump?
Not automatically. They have different housings and may require changes to mounting, hose position or clearance. Check the exact MPN and installation dimensions before changing designs.
Does a non-automatic bilge pump switch itself on when water rises?
Not unless it has a compatible automatic level switch or control system. Match manual or automatic control to your intended installation and use correctly rated electrical protection.

Always comply with the vessel manufacturer's bilge-system instructions. A bilge pump is not a substitute for resolving leaks or maintaining required safety equipment.
