Rule-Mate Compact Automatic Bilge Pump - 500GPH - 12v
Manage bilge water with this 12v Rule Rule-Mate automatic pump. Product 189241 is the 500GPH version with a 20mm hose connection, giving you the key electrical and plumbing details to match to your boat.
An internal water-level sensor starts the pump at 62 mm and stops it at 16 mm. This automatic operation responds to water depth without requiring a separate external float switch.
Hidden body vents help resist air locking, while the discharge check valve prevents water running back into the bilge through the nozzle.
Match the 12v electrical supply and 20mm discharge connection before choosing this code. Check the measured installation space against the listed pump dimensions, allowing access to the strainer and hose connection.
Choosing and using this product
Compare the package contents with the complete installation you are planning. Pump-only listings and kits can differ in switches, fittings and hoses. Listing the required components before ordering helps you select the appropriate package and avoids treating an illustrated accessory as an included part.
A flow figure alone does not describe the complete installation. Hose routing, outlet height and the rest of the plumbing can affect the delivered result. Use the relevant pump guidance when sizing the system rather than treating a catalogue flow figure as a guaranteed output at every outlet.
For this version, size: 120 x 74 x 64mm. Use that specific detail when comparing the item with your existing equipment or planned installation. Other sizes and configurations in the range should be checked separately rather than treated as equivalent.
Select the pump or service component for the actual job: bilge drainage, fresh water, washdown, livewell circulation and waste handling place different demands on a system. Match the stated application first, then compare the power supply, connections and operating details for this exact version.
