Light-Duty Pedestal Rotary External Gear Pumps
Shertech self-priming, positive displacement, external rotary gear pumps are ideal for a wide range of light-duty industrial, marine, agricultural, and commercial applications, providing a nearly pulseless flow and are designed specifically for reduced speed operations. Some models include an internal pressure relief valve. Limited self-priming capability on packing seal types. Pillow block shaft assembly is required when pulley driven. Motors are not included. Uses: For use with non-particulate and non-abrasive fluids compatible with pump wet-end construction component materials.
• Flows to 24.8 GPM
• Max. RPM: 1725
• Max. PSI: 100
• Suction lift to 19.5 ft.
• Maximum viscosity of 100,000 SSU at reduced speed (max. input torque of 45 -160 in.-lbs.)
• Temperature ranges from -20 to 280° F
• Seals – Viton lip or Kevlar®/Teflon® packing type
• Bushings – Steel, bronze or carbon/graphite
• Maximum working pressure: 130 PSI
• Pumps can operate bi-directionally (reversible). In the opposite rotation, the pump pressure relief valve, if equipped, will not function.
BRONZE – Excellent for water-based fluids. Pumps have 303 stainless steel shafts. Models without zerks are available with or without internal pressure relief valves and include carbon graphite drive shaft bushings. Packing Kevlar®/Teflon® seal with temperature range of -20° to 210° F. Wet-end parts: Zerk models are constructed from stainless steel (17-7, 300 series and/or 18-8), bronze, brass, vellumoid, Kevlar®, and Teflon®. Non-zerk models are constructed from 303 stainless steel, bronze, brass, vellumoid, carbon, graphite, Kevlar®, and Teflon®. Models that include internal pressure relief valves also have stainless steel (17-7, 300 series and/or 18-8) wet-end components.
CAST IRON – Specifically designed for use with oil-based fluids. Not to be used with water-based fluids. Models without grease zerks include steel spur gears with steel shafts, cast iron shaft support, Viton® lip seals having a temperature range of 32° to 280° F. Wet-end parts are constructed from cast iron, stainless steel (17-7, 300 series and/or 18-8), steel, vellumoid, and Viton. Models with grease zerks include steel spur gears with steel shafts, cast iron shaft support, Kevlar®, and Teflon® packing seals having a temperature range of -20° to 210° F. Wet-end parts are constructed from cast iron, stainless steel (17-7, 300 series and/or 18-8), steel, vellumoid, Kevlar®, and Teflon®.
NOTE: Not for pulley drive systems without the use of a pillow block shaft assembly. See Rotary Gear Pump Selection Guide in the Motor Manual for suggestions concerning installation, selections, options, and accessories. For direct driving pumps, a coupler is required.
NOTE: Models with bearings and mechanical seal available as well as close-coupled.
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.
