When you need reliable fuel handling equipment for marine applications, Rule Industries brings over 50 years of pump engineering expertise to the oil, diesel, and fuel transfer pump category. While Rule is best known for their industry-leading bilge pumps, their fuel transfer solutions apply the same marine-grade durability and performance standards that have made them a trusted name among commercial fishermen and recreational boaters worldwide.
Rotary Sliding-Vane Technology for Marine Fuel Transfer
Rule's DC sliding-vane pumps are purpose-designed to handle diesel fuel, gas oil, kerosene and paraffin rapidly and efficiently, delivering high flow rates with minimal battery drain, with positive sliding-vane action that ensures quick self-priming from dry. These self-priming pumps are designed to function in all sorts of conditions: from -22°F in Alaska to 104°F in Baja, making them ideal for vessels operating in diverse climates. Unlike a centrifugal pump, the Rule sliding-vane pump clears most of the residual fuel from the hose when the supply vessel is empty, reducing waste and simplifying tank transfers.
Marine-Specific Design Features
The cast iron body features two mounting feet for permanent installations, with an integrated switch, fuse and barbed fittings for 1" hose that makes set up quick and easy. An IP55 rating gives users the confidence that this pump will standup to moderate exposure to dust and spray, critical for engine room installations and exposed deck locations. Rule's fuel transfer pumps typically deliver flow rates around 13 GPM for diesel applications, making them well-suited for tanks ranging from 50 to 200 gallons—the sweet spot for most mid-sized recreational and light commercial vessels.
Trusted Marine Heritage
Xylem's Rule brand is globally recognized for its high-performance marine pumps and fluid management systems, trusted by boaters for decades and best known for its industry-leading bilge pumps, which are engineered for reliability, efficiency, and durability in the harshest marine environments. This marine-first design philosophy carries directly into their fuel transfer products, where corrosion resistance, vibration tolerance, and ignition protection meet Coast Guard and ISO marine standards. Whether you're refueling at the dock, transferring diesel from drums to onboard tanks, or balancing fuel between port and starboard tanks, Rule's pump engineering provides the dependability that marine environments demand.
Applications Beyond Basic Transfer
Rule fuel transfer pumps excel in multiple marine scenarios: dockside refueling, engine room permanent installations for fuel polishing systems, hydraulic oil service for steering and stabilizer systems, and even emergency fuel management when tank switching becomes necessary. Rule pumps handle fresh and sea water or diesel fuel, offering versatility for vessels requiring multi-purpose pump solutions. The 12V DC operation integrates seamlessly with existing marine electrical systems, while the continuous-duty rating on many models supports extended pumping operations without thermal shutdown concerns that plague lesser pumps in demanding marine service.
