SHURflo Bronze Pedestal Self-Priming
Flexible Impeller Pumps
Refer to form L-4082 for General Operating and Safety Instructions.
Description
SHURflo bronze, pedestal, self-priming, positive-displacement, flexible impeller pumps provide a nearly pulseless flow with no
metal-to-metal contact. This pedestal pump drive series includes a 303 stainless steel drive shaft with heavy-duty ball bearing
and carbon graphite bushing, providing for direct drive or pulley operation. Features include: bronze and/or brass pump
body, cam and cover; standard Buna-N mechanical seal with carbon ceramic faces and Nitrile impeller.
Uses: Handle a wide range of industrial, marine, agricultural and commercial applications where non-abrasive fluids
compatible with pump wet-end construction component materials are pumped. Pumps are suitable for the transfer of
non-lubricating fluids, mild abrasives, fluids containing small particles in suspension, and a wide variety of viscous fluids such
as petroleum-based oils, silicone greases, and hydraulic fluids. These units are ideal for water drainage transfer, barrel
emptying, machine coolant recycling, and an assortment of related utility activities.
NOTE: Flexible impeller failure will occur immediately if pump is run dry, and this is not covered under warranty. Use caution
to not touch the pump if you have dry run it, because it will be extremely hot.
• Flows up to 36.5 GPM at 3450 RPM.
• Maximum discharge pressure is 25 PSI (60 ft. of head).
• Max. RPM: 3450.
• Suction lift to 13.5 ft.
• Buna-N mechanical seal with carbon ceramic wear faces and 18-8 stainless steel components.
• Maximum viscosity up to 500 SSU and 25 PSI (60 ft. of head) at 1725 RPM or run at reduced speeds to handle a wide range
of pump fluid viscosities (up to 2500 SSU) and specific gravity (up to 1.3). DO NOT pump oils or petroleum derivatives with
optional neoprene impellers. (Maximum torque loads are found in the performance chart.)
• Pumps can operate bi-directionally (reversible).
• Temperature range with Nitrile impellers is 0°F - 180°F (optional neoprene impellers is 15°F - 130°F).
Includes a 303 stainless steel drive shaft with heavy-duty ball bearing and carbon graphite bushing, providing for direct
•
drive or pulley operation.
BRONZE MODELS – Excellent for water-based fluids. Features include: bronze and/or brass pump body, cam and cover; standard
et-end parts are constructed from bronze, brass, Nitrile,
W
Buna-N mechanical seal with carbon ceramic faces and Nitrile impeller
carbon, ceramic and stainless steel (18-8, 303 and/or other 300 series).
REPAIR IMPELLERS AND OPTIONS – Standard impellers are Nitrile, and they and the optional neoprene impeller can be
located in the repair parts list pages in this manual.
NOTE: Bronze and 316 stainless steel flexible impeller pumps are also available as close-coupled models for custom installation. They are
equipped with motors.
.
ARNING: Do not use to pump flammable or explosive fluids such as gasoline, fuel oil, kerosene, etc. Do not use in flammable
W
and/or explosive atmospheres. When pumping hazardous or dangerous materials, use only in a room or area designated for that
purpose. For your protection, always wear proper clothing, eye protection, etc. in case of any malfunction. For proper handling techniques
and cautions, contact your chemical supplier, insurance company and local agencies (fire dept., etc.). Failure to comply with this warning
could result in personal injury and/or property damage.

may require ordering standard components and/or optional parts that
will need to be assembled by the customer.
Manufacturer reserves the right to change model order codes, stan

Maximum motor speed is 3600 RPM.
R series pumps are all pedestal mounts for multi-speed configurations.

Test data taken with water at 70° F (to convert data to PSI, divide feet of head by 2.31).
Pump performance when pump is new. As pump wears, the performance will decrease.
(†) Extended operation beyond 60 feet of head will result in immediate impeller failure.
(*) Female NPT inlet and outlet (in inches).
(**) Suggested horsepower; pumps do not ship with motors.
(***) Suction lift requires wetted impellers and seal chamber.
NOTES: Consult tables on HP adders and speed recommendations for high viscosity fluids. The pump relationship between volume (GPM),
pressure (PSI), speed (RPM) and horsepower is shown on Performance Chart in Shurflo Motor Manual form L-4082. When pumping
a more viscous liquid, a slower speed, a larger pipe size pump, and possibly a larger motor should be selected.
Max. Viscosity = 500 SSU at 1725 RPM (at 1.0 specific gravity).
Max. Input Torque = see chart above.
Max. RPM = 3450.
Max. Specific Gravity = 1.0 at 25 PSI, up to 1.3 at lower PSI & viscosity.
Do not use Neoprene impellers with oil.
Manufacturer reserves the right to change performance without notification.
