Superior build quality and ease-of-use features ensure continued great performance, even after years of hard use. Entire unit, both pump and engine, built by Subaru Robin to very high standards. All models feature construction-grade features, plus easy starting, whisper-quiet running, easy & safe operation, long running time, low maintenance & long engine life. Subaru Robin is the fourth largest engine manufacturer in the world, with distribution for over forty years. Subaru Robin Portable Pumps have earned an enduring reputation for high quality & performance.
Four Models: 1, 2, 3, 4-Inch Inlet/Outlet;
28 to 356 gpm
A centrifugal pump works similar to sucking on a straw.
An engine turns an impeller, forcing water around it
and out a discharge port. Centrifugal pumps deliver
liquid at uniform pressure without shocks or pulsations,
and can handle liquids with some amounts of small solids
in suspension. Having only one easy-to-repair wearing
part (a seal) a centrifugal pump needs no lubrication,
gears, pistons, or diaphragms. The simplicity, compactness,
weight saving, adaptability to high-speeds, and economy
make centrifugal pumps ideal for a wide variety of general
applications. All Subaru Robin centrifugal pumps are
self-priming.
One Model: 3-Inch Inlet/Outlet; 85 gpm
Diaphragm pumps isolate the pump mechanism from fluid
being pumped. This makes them ideal for pumping
chemicals, abrasives, slurries, viscous products, seawater,
re-circulated water and many other fluids. Diaphragm
pumps can handle sticks, stones, debris, mud, trash,
and solids up to mesh sizes specified by model. Positive
displacement type, hermetically sealed compression chamber
prevents loss of gases or liquids being handled, making
diaphragm pumps ideal for handling compression &
evacuation of precious, toxic, corrosive, inflammable,
radio-active, or otherwise dangerous gases.
One Model: 2-Inch Inlet/Outlet; 127 gpm
High pressure pumps employ a larger diameter impeller
having more and shallower vanes to attain higher pressures.
These models offer more powerful performance with very
high output, higher discharge heights, and capacity
to pump longer distance through hoses.
Two Models: 2, 3-Inch Inlet/Outlet; 153 to
246 gpm
Semi-Trash pumps handle light debris for heavy-duty
de-watering applications. A semi-trash pump employs
deeper impeller vanes, incorporated with a larger volute
discharge opening to pass water containing suspended
particulate matter and small solid objects. Subaru Robin
semi-trash pumps are self-priming, semi-trash type,
designed to move high volumes of water fast, allowing
passage of solids to flow through the pump without clogging
(up to 1/4-inch diam. for 2-inch model; up to 3/4-inch
diam. for 3-inch model).
Three Models: 2, 3, 4-Inch Inlet/Outlet; 185
to 528 gpm
Trash pumps handle larger solids & debris for heavy-duty
de-watering applications. A trash pump employs the deepest
impeller vanes to produce the largest discharge capacity,
incorporated with a large volute discharge opening to
pass water containing suspended sticks, stones &
debris without clogging or harming pump components.
Subaru Robin trash pumps are self-priming trash type,
designed to move high volumes of water fast, allowing
passage of solids to flow through the pump without clogging
(up to 3/4-inch diam. for 2-inch models; up to 1-1/4-inch
diam. for 3- and 4-inch models).
