<strong>SHURflo</strong> Commercial-Duty Filter <strong>and</strong> Rendering OilRotary Close-Coupled External Gear PumpsRefer to form L-4082 for General Operating <strong>and</strong> Safety Instructions.COMPONENTGEAR AND ROLLER PUMPSDescription<strong>SHURflo</strong> self-priming, positive displacement, external gear, hot oil pumps feature cast-iron construction, with Vitonmechanical seal for high temperature use. This series of non-clogging pumps are highly recommended for high flow waste oilrendering because they are able to pass small non-abrasive particles <strong>and</strong> reduce oil shear. Features include heavy-duty stainlesssteel helical non-corrosive gears for quiet <strong>and</strong> long-life pumping action, carbon graphite bushings <strong>and</strong> ball bearing drive forcontinuous use, with a stainless steel adjustable pressure relief valve as st<strong>and</strong>ard equipment. This series of pumps can also beused for hot oil or frying oil filtration up to 375° F., meeting NSF-listing requirements. Pumps are configured with motorsspecifically for hot oil applications where oil is heated prior to pumping <strong>and</strong> discharge pressure limitations do not exceed50 PSI with supplied motors. They provide a nearly pulseless flow in applications where small or non-particulate <strong>and</strong> nonabrasivefluids are pumped. AC ODP single-phase motors have thermal overload protection. Complete package is easy toinstall, or optional pump heads only can be purchased for custom installations.Uses: Ideal for a wide range of commercial fat fryer hot oil cooking, filtering, or waste oil rendering applications. This pumpcan also be used in non-NSF hot oil applications with non-particulate <strong>and</strong> non-abrasive fluids compatible with pump wet-endconstruction component materials. Not for use with water-based fluids.• Pumps meet NSF-listed st<strong>and</strong>ards including NSF-accepted paint for hot oil cooking applications.• Pumps can operate bi-directionally (reverse operation should be used intermittently).• Pressures to 125 PSI with pump heads.• Pressures to 50 PSI, maximum viscosity of 100 SSU <strong>and</strong> maximum specific gravity of 1.1 with configured motors.• Flows to 10.8 GPM.• Operating temperatures to 375° F.• Maximum viscosity of 1000 SSU <strong>and</strong> maximum specific gravity of 1.1 with pump heads <strong>and</strong> optional motors at 1725 RPM,<strong>and</strong> viscosities up to 100,000 SSU at reduced motor speeds.• Suction lift capabilities up to 12.3 feet of head.• Maximum RPM: 1725.• <strong>Stainless</strong> steel adjustable pressure relief valve st<strong>and</strong>ard.• Port size: 1/2" <strong>and</strong>/or 3/4".• ODP single-phase 56C frame motors with 1/2 or 3/4 HP with thermal overload protection.• 416 SS helical gear set for h<strong>and</strong>ling high viscosity fluids <strong>and</strong> low oil shear.• 303 SS drive shaft <strong>and</strong> idler shaft with carbon graphite bushings <strong>and</strong> a ball bearing drive.• Seal flush ports for h<strong>and</strong>ling fluids of viscosities greater than 2000 SSU.• Maximum case pressure of 200 PSI.Wet-end parts are constructed from cast iron, steel, stainless steel (303, 17-7, 18-8, 416, 15-7MO), carbon, graphite, Type 1Ni-Resist, <strong>and</strong> Viton.Optional Close-Coupled Gear Speed Reducers are available that mount directly between pump <strong>and</strong> motor to reduce pump speedfor high viscosity or high specific gravity applications (See Appendix 1).WARNING: Do not use to pump flammable or explosive fluids such as gasoline, fuel oil, kerosene, etc. Do not use in flammable <strong>and</strong>/orexplosive atmospheres. When pumping hazardous or dangerous materials, use only in room or area designated for that purpose. Foryour protection, always wear proper clothing, eye protection, etc. in case of any malfunction. For proper h<strong>and</strong>ling techniques <strong>and</strong> cautions,contact your chemical supplier, insurance company <strong>and</strong> local agencies (fire dept., etc.). Failure to comply with this warning could result inpersonal injury <strong>and</strong>/or property damage.Source: Owner’s Manual L-4092 (11/10)62www.shurfloindustrial.comEffective 1/1/2011Form 45-SHU
