GORMAN-RUPP SETS A WHOLE NEW STANDARD IN
PRIMING-ASSISTED PERFORMANCE
Gorman-Rupp, the world’s leading manufacturer
of pumps, has revolutionized the construction
pumping industry. Gorman-Rupp now offers the
biggest and broadest
range of primingassisted (dry prime)
pumps.
GORMAN-RUPP OFFERS
THE BROADEST RANGE OF
PRIMING-ASSISTED PUMPS
With sizes from 3" to 30", heads up to 475 ft., flows
up to 40,000 GPM and 6" solids-handling capability,
Gorman-Rupp’s extensive line of hard-working, dependable
pumps will tackle everything, including clear liquids, tough
solids, and slurry applications.*
You can choose the Prime Aire® venturi priming system
or the Redi-Prime® diaphragm priming system. Both offer
auto­matic priming and repriming.
For sewage bypass operations, construction site dewatering
or other applications where intermittent flow can be a
problem, these dependable, versatile
performers help contractors move large
volumes of water rapidly, even when
sticks, stones, and debris would
normally present a problem.
All of Gorman-Rupp’s priming-assisted
(dry prime) pumps are designed and
engineered for the most rugged
and demanding construction
applications and are backed
by an industryleading two year
warranty.
*For larger flows, contact the factory. Additional pump models
are available up to 30" in size and up to 40,000 GPM.
Available in pedestal and SAE pump ends
for connection to customer driver.

PRIME AIRE® PUMPS FEATURE GORMAN-RUPP’S
UNIQUE PRIMING SYSTEM
THIS SYSTEM USES a venturi and a compressor, which eliminates the leaks associated with traditional
vacuum-assisted pumps. This unique system not only reduces environmental concerns on sewage bypass operations
and other environmentally hazardous liquids, but it also enables the pumps to operate under flooded suction
conditions without leaking. The positive priming of the Prime Aire® is well suited for applications involving long suction lines, intermittent flows
or large volumes of air in the liquid being pumped.
DRY RUN CAPABILITY is designed into the Prime Aire® system.
An oversized, oil-lubricated mechanical seal allows the pump to run dry
continuously without damage. For positive, reliable priming time after
time, Gorman-Rupp Prime Aire®
pumps are the ones you can count on.
DUAL-SUCTION SIDE
CAPABILITY, on model
PA6C,
features a removable coverplate and
adjustable/ replaceable wearplate.
COMPRESSOR OVER PUMP
Several popular models are
available in a “Compressor-OverPump” arrangement. This innovative
configuration option offers a selfcontained, compact, flexible design
while allowing ease of operation and
servicing when needed.
SOLIDS HANDLING IMPELLER
Many Prime Aire® pumps feature rugged
open-type, two-vane ductile iron impellers
that are specifically designed to handle solids
and debris up to 4" (102 mm) in diameter. This
means fewer clogs and more productivity on
tough jobs.
ABRASIVE HANDLING SEAL
Prime Aire® pumps are equipped with
oversized, mechanical, oil-lubricated, double-floating, self-aligning
seals with silicon carbide rotating and stationary faces that are
designed to take the wear and tear of pumping solids, slurries and
other abrasives.
STANDARD AUTO-START CONTROLS
Auto-Start control starts and stops the
pump in response to a liquid level. The
pump starts only when there is water
to pump and turns itself off when the
water reaches the desired level. There
is never any need to waste fuel and
add to costly engine overhauls.

Models are engineered with highly
efficient, enclosed impellers, with some
models using double volutes increasing
the performance far beyond many
competitor’s pumps. The Cycloseal®
design, with its impeller backvanes
and unique deflector vanes, assists in
removing solids and abrasive materials
from the seal area – in some cases
more than tripling the normally expected
mechanical seal life.

lubricant reservoir so that shaft rotation provides circulation and
