External Gear Pumps

PumpsCarotek offers many different types of external gear pumps from Viking Pumps and Pulsafeeder. These cover most types of industrial applications from food to chemicals to general industrial applications.

Viking Spur Gear and Mag Drive External Gear Pumps

  • Higher Pressure Capabilities - with shaft support on both sides of the gears
  • Multi-Section Pumps can be used for blending liquids, or splitting flows to different uses
  • Shaft Seal Options - lip seal, component seal, cartridge seal and seal-less mag drive
  • Multiple Porting Options
  • Compact, Close Coupled for gear motors or motor speed operation
  • Accurate flow measurement with minimal pulsation
  • Only two moving parts make them reliable and easy to maintain


  • Max Capacity to 190 GPM (45 M3/Hr)
  • Max Pressure to 2,500 PSI (170 BAR)
  • Viscosity Range: 28 to 1,000,000 SSU (1 to 250,000 cSt)
  • Temperature Range: -40°F to +450°F (-40°C to +230°C)

Eclipse, Isochem and ECOchem External Gear Pumps

Eclipse – Non Metallic Magnetic Drive Pump

  • PumpsEclipse pumps are built for use in the harshest industrial environments, especially good for many corrosive liquid applications used in chemical processing, pulp and
  • paper, and water treatment
  • Corrosion-resistant materials are used for pump housings, gear assemblies, shafts and magnetic couplings
  • Eclipse pumps are reliable, simple and intuitive, combining state of the art engineered composites with proven design principles
  • Maintenance costs and process downtime are reduced because the pump can be serviced in place in a matter of minutes
  • Optional Pressure Relief Valves and Power Monitors can protect your pump from jamming, dry-run or over pressurization
  • Performance:
    • Flow: -up to 33 gpm (125 lpm)
    • Pressure: up to 150 psi (10 bar)
    • Temperature: 150°F (66°C) , 200°F (93°C) with deration

Isochem – High Alloy Metallic Magnetic Drive Pump

  • PumpsIsochem pumps handle a broad range of applications over wide temperature, viscosity, and pressure variations, safely handling toxic, explosive and hazardous fluids over the entire PH range
  • Because they are seal-less, they can be used to meet federal regulations for safe, leak-free service and save downtime and maintenance costs
  • Materials of construction start with 316 Stainless Steel and move into higher alloys like Hastelloy and Alloy 20 for superior corrosion resistance
  • Performance:
    • Flow: up to 84 gpm (317.97 lpm)
    • Pressure: up to 365 Ft. (111.25 m)
    • Temperature: up to 450°F (232°C)

ECO Gearchem – High Alloy Metallic Sealed Pump

  • PumpsECO Gearchem pumps provide reliability and versatility over a wide range of temperatures, pressures and corrosion levels
  • This self-priming, external-spur gear pump can safely handle clear lubricating and non-lubricating liquids
  • Extensive material availability provides versatility for pumping low or high viscosity fluids
  • ECO Gearchem pumps provide linear, pulsation-free flows, and the pump flow direction can be easily changed
  • Best used for chemical transfer, cyclic operations, continuous production systems, both open-end, and closed loop, pilot plants, vacuum systems, and metering applications
  • Performance:
    • Flow: up to 22 gpm (100 lpm)
    • Pressure: up to 200 psig (13.8 bar)
    • Temperature: up to 450°F (232°C)
