SHURflo Heavy-Duty Cast Iron and Bronze
Rotary Close-Coupled External Gear Pumps
Description
SHURflo self-priming, positive displacement, rotary external gear pumps provide a nearly pulseless flow. Standard models
are mounted directly to NEMA frame AC Open Drip-Proof (ODP) motors using an easy-installation package, or as pump heads
only for custom installations. Standard safety pressure relief valve that is included can be ported internally or externally.
Single-phase motors are thermally overload protected; 3-phase ODP motors are not.
Uses: Handle a wide range of industrial, marine, agricultural and commercial applications where non-abrasive and
non-particulated fluids compatible with pump wet-end construction component materials are pumped.
•Capacities up to 24.8 GPM.
•Maximum pressure to 125 PSI and working casing pressure to 200 PSI.
• Max. RPM: 1725.
•Suction lift to 19.5 ft.
•Mechanical seals (Viton or Buna) with carbon on ceramic faces with engineered flush chamber for internal or external flush to
handle viscosities beyond 2000 SSU.
• Pumps with electric motors are configured to handle up to 500 SSU and 125 PSI at 1725 RPM or run at reduced speeds to
handle a wide range of pump fluid viscosities and specific gravity up to 100,000 SSU. (Maximum torque loads are found
in the performance chart.)
• Pumps can operate bi-directionally (reversible).
• Temperature ranges from -20°to 280°F.
•Standard adjustable pressure relief valves that can be internally or externally ported are standard.
BRONZE MODELS – Excellent for water-based fluids. Ryton PPS (Polyphenylene Sulfide) spur gears provide quiet operation and
chemical compatibility. No metal-to-metal contact. Pumps also have 303 stainless steel shafts and carbon graphite bushings.
Buna-N mechanical seal with temperature range of -20° to 210° F. Wet-end parts are constructed from bronze, brass, Ryton PPS,
stainless steel (17-7, 303 and/or 18-8), vellumoid, graphite, carbon, ceramic, and Buna-N.
CAST IRON MODELS – Specifically designed to be used with oil-based fluids, not to be used with water-based fluids. Pumps include
steel spur gears with steel shafts and cast iron shaft support. Viton mechanical seal has temperature range of 32° to 280° F. Wet-end
parts are constructed from cast iron, steel, stainless steel (17-7, 303 and/or 18-8), vellumoid, carbon, ceramic and Viton.
REPAIR SEALS AND OPTIONS – Standard seals are Viton and Buna-N with carbon on ceramic faces. Standard seals can be locat-
ed in the repair parts list pages in this manual. When switching between Viton and Buna-N mechanical seals, be sure to order
the matching o-rings in the same material. These can be found in the repair parts list pages in this manual.
Optional Close-Coupled Gear Speed Reducers are available that mount directly between pump and motor to reduce pump speed
for high viscosity or high specific gravity applications (See Appendix 2).
NOTE: This series of gear pumps is also available as pedestal models for custom installation. They are not equipped with motors.
WARNING: Do not use to pump flammable or explosive fluids such as gasoline, fuel oil, kerosene, etc. Do not use in flammable
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.

Test data taken on SAE 10 wt. oil at 70° F (500 SSU).
Performance in water will decrease by about 10%, and HP required will also be reduced by 10%. (Don’tuse water with Cast Iron.)
Pump performance when pump is new.As pump wears, the performance will decrease.
(*) Female NPT inlet and outlet (in inches) .
(**) Suction lift requires wetted gears and primed seal chamber.
(***) Motor not provided.
NOTES: Pumps with motors are HP rated to handle up to 500 SSU at 125 PSI and specific gravity of 1.0.
Max. PSI = 125
Max. Viscosity = 500 SSU at 1725 RPM with standard spur gears
Max. RPM = 1725
Max. Specific Gravity = 1.1 at 125 PSI, up to 1.6 at lower PSI & viscosity.
Max. Input Torque = See chart above.
Reverse Rotation = Pumps are equipped with pressure relief valves and can be run in reverse rotation; however,pressure relief valve will not function when
pump is reversed unless pump relief valve cover is rotated 180°.
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.
Manufacturer reserves the right to change performance without notification.
