Pump Overview:

Pump Family Overview:
Centrifugal pumps deliver liquid at uniform pressure without shocks or pulsations. Having only one easy-to-replace wearing part (a seal), Subaru's centrifugal construction pumps are easy to maintain, requiring no lubrication, gears, pistons or diaphragms. The simplicity, compactness and economical design make them ideal for a wide variety of general applications. And best of all, every pump is powered by Subaru’s industry leading 4-cycle engine technology, ensuring optimum performance and reliability.

   Key Features & Benefits:
Aluminum Die Cast Pump Housing Lightweight die-cast aluminum pump housing provides strong durability against damaging debris.
Cast Iron Impeller and Volute Cast-iron impeller and volute ensure maximum durability and performance in consistently demanding applications.
Ceramic Carbon Mechanical Seal Self-lubricating carbon ceramic mechanical seal provides rugged construction for long unit life.
Fuel Shut-Off Valve with Sediment Cup Shut-off valve is used when transporting or servicing the pump. The translucent sediment cup and filter allow the operator to see if any water or dirt have entered the engine. The cup can be removed, cleaned and reinstalled.
Fuel Tank with Strainer Large metal fuel tank provides extended run times between refills. The fuel strainer prevents debris from entering the tank.
Full Tubular Wrap-Around Frame All models include a steel wrap frame to protect all sided of the unit.
Large Air Filter Element The air cleaner element can be cleaned and reused to save money. Check the owner's manual for the correct cleaning procedure.
Low Oil Shutdown Subaru engines incorporate a low oil shutdown that shuts off the engine when low oil level is detected.
Muffler with Spark Arrestor Subaru specifically engineers each muffler to each engine, therefore providing optimum sound reduction. Each muffler includes a US Forestry-approved spark arrestor.
Shimmable Impeller to Volute Shims allow the clearance to be readjusted between the impeller and volute as the pump wears from dirt and grim. This saves the cost of replacing the major pump components.
Standard Accessories Standard accessories include tool kit, vibration isolators, and hose bands.
Self Priming Self priming pumps require initial priming to operate.
