Rule has built electric submersible bilge pumps for more than 50 years, and its pumps are found in boats of every size, from rowing boats to workboats. Rule is part of Xylem, as is Jabsco.
In the latest generation of Rule pumps the impeller is shaped to deliver more flow for the same current draw. The pumps have built-in thermal protection, a valve that reduces backflow, hidden air vents that prevent air locking and a threaded discharge port.
Marine Import Oy is the official Rule distributor in Finland. We keep the most common pumps, switches and accessories in stock in Luvia, and stock items are dispatched within 1–3 working days. We also deliver to business customers in the Baltics, Sweden, Denmark, Germany and Poland.
The Rule model number gives the rated flow in US gallons per hour: a Rule 1100, for example, delivers about 69 litres per minute. Individual models and availability are listed in our Captains Shop online store (in Finnish).
The classic Rule pump sits at the bottom of the bilge and is started from a switch, a control panel or a separate float switch.
In the automatic models the switch is built into the pump. The pump runs briefly about every 2.5 minutes and senses from the motor load whether there is water in the housing.
RuleMate senses the water level electronically with no moving parts. The pump starts when water reaches the sensor and stops when the bilge is empty.
LoPro 900 fits shallow, tight bilges. It can be installed upright or on its side, and the discharge rotates through 180 degrees.
A separate float switch makes a standard bilge pump automatic. Choose the switch by the pump’s current and the boat’s voltage.
A waterproof control panel selects automatic, off or manual operation, and a light shows when the pump is running. A high water alarm warns if water keeps rising despite the pump.
Livewell pumps circulate and aerate water in fish and bait tanks. The pump is mounted on a through-hull fitting.
The rated flow in the model number is measured with no head. On board, the pump lifts water through the hose to the through-hull, and flow falls the higher the water has to rise.
Long hoses, bends, rough hose walls, check valves and low voltage all reduce flow further. Choose a pump whose flow is still enough at your boat’s real lift height.
| Model | Rated | 1 m | 2 m | Max. head |
|---|---|---|---|---|
| Rule 360 | 23 l/min | 19 l/min | 9.5 l/min | 3.7 m |
| Rule 500 | 31 l/min | 30 l/min | 17 l/min | 3.4 m |
| Rule 800 | 50 l/min | 50 l/min | 36 l/min | 3.7 m |
| Rule 1100 | 69 l/min | 63 l/min | 52 l/min | 3.0 m |
Manufacturer’s measured values for standard Rule submersible pumps. On board, flow also depends on the hose and voltage.
Rule bilge pumps are certified to ISO 8849 for electric bilge pumps and ISO 8846 for ignition protection. An ignition-protected pump will not ignite fuel vapour, so it is suitable for the bilge of petrol-powered boats.
The pumps also follow the ABYC recommendations for boat electrical systems. On request we provide model-specific data for procurement or inspection.

It is the pump’s rated flow in US gallons per hour. A Rule 500 delivers about 31 l/min and a Rule 2000 about 126 l/min with no head.
Automatic Rule pumps and RuleMate have the switch built in, so no separate switch is needed. A standard pump becomes automatic with a Rule-A-Matic or Super Switch.
