SHURflo Heavy-Duty Cast Iron and BronzePedestal Rotary External Gear PumpsRefer to form L-4082 for General Operating and Safety Instructions and Applicable Warranty.GEAR AND ROLLER PUMPSDescriptionSHURflo self-priming, positive displacement, external rotary gear pumps operate bi-directionally (reversible) and are ideal fora wide range of industrial, marine, agricultural, and commercial applications. They provide a nearly pulseless flow wherenon-abrasive and non-particulated fluids are pumped.Quality features include a keyed drive shaft supported by heavy-duty ball bearing, large bushing support and an adjustablepressure relief valve that can be ported internally or externally. Motor HP recommendations are listed in the performance chart.Uses: For use with non-particulate and non-abrasive fluids compatible with pump wet-end construction component materials.• 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.• Temperatures from -20° to 280° F.• Large female NPT ports allow use with viscous fluids.• Pumps can be long-coupled with electric motors to handle up to 500 SSU at 1725 RPM or run at reduced speeds to handle a widerange of pump fluid specific gravities and viscosities up to 100,000 SSU. (Maximum torque loads are found in the performance chart.)• Mechanical seals (Viton, Teflon ® or Buna) with carbon on ceramic faces with engineered flush chamber for internal or externalflush to handle viscosities beyond 2000 SSU.• Pumps can operate bi-directionally (reversible).• Ball bearing shaft support allows for pulley drive.• Standard adjustable pressure relief valves that can be internally or externally ported.BRONZE MODELS – Excellent for water-based fluids. Ryton PPS (Polyphenylene Sulfide) spur gears provide quiet operationand chemical compatibility. No metal-to-metal contact. Pumps have 303 stainless steel shafts and carbon graphite bushings.Buna-N mechanical seal with carbon on ceramic faces has a temperature range of -20° to 210° F. Wet-end parts are constructedfrom bronze, brass, Ryton PPS, stainless steel (17-7, 303 and/or 18-8), graphite, carbon, ceramic, vellumoid, and Buna-N.CAST IRON MODELS – These pumps are specifically designed to be used with oil-based fluids, not to be used with water-basedfluids. Pumps include steel spur gears with steel shafts and cast iron shaft support. Viton mechanical seal with carbon on ceramicfaces has a 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), carbon, ceramic, Viton, and vellumoid.REPAIR SEALS AND OPTIONS – Standard seals are Viton and Buna-N with carbon on ceramic faces. An optional Teflon ® seal of316 SS construction with carbon on ceramic faces is available. Standard seals can be located in the repair parts list pages inthis manual. When ordering optional mechanical seals, be sure to order the optional o-rings in the same material. These canbe found in the repair parts section in this manual.NOTE: This series of gear pumps is also available as close-coupled models equipped with motors.WARNING: Do not use to pump flammable or explosive fluids such as gasoline, fuel oil, kerosene, etc. Do not use in flammableand/or explosive atmospheres. When pumping hazardous or dangerous materials, use only in a room or area designated for thatpurpose. For your protection, always wear proper clothing, eye protection, etc. in case of any malfunction. For proper handling techniquesand cautions, contact your chemical supplier, insurance company and local agencies (fire dept., etc.). Failure to comply with this warningcould result in personal injury and/or property damage.Source: Owner’s Manual L-4086 (12/09)46www.shurfloindustrial.comEffective 1/1/2011Form 45-SHU

Custom model configurationsmay 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, standard models, specifications, and performance without notification.(*) ODP motors have > 1.15 service factors. Due to service factor, it is recommended TEFC motors are oversized by one HP increment.Pedestal Pumps are not supplied with a motor.(**) Bronze models have Ryton PPS (Polyphenylene Sulfide) gears. Cast Iron models have steel gears.Maximum motor speed is 1725 RPM.Cast iron is not for use with water-based fluids.Source: Owner’s Manual L-4086 (12/09)Effective 1/1/2011Form 45-SHUsales@shurfloindustrial.com47
