Features

  • Patented Non-Symmetrical Gears The adoption of non-symmetrical gears insures greater power per unit volume compared with pumps of conventional design. The compact gear compartment has enabled high-pressure operation. The increased number of gear teeth has reduced the flow pulsation and minimized the noise.
    • U.S.A. Patent No. 3817117
    • U.K. Patent No. 1400577
    • French Patent No. 7230448
    • German Patent No. 7231801 Others: Pending
  • Bearings PTFE composite bearings are used due to the ability to handle heavy loads, low shaft speeds, and high levels of contamination. Engineering tests on the PTFE bearings indicate they will withstand bearing loads over twice as high as conventional steel backed aluminum bearings used in many pumps. The PTFE resin layer will absorb a high degree of contamination with out damage to the pump. Also since the PTFE layer is self lubricating, contamination from bearing wear in high load situations (when no oil film is present) is reduced. The side benefit from reduced friction under all conditions is a reduced consumption of power.
  • Gears and drive shaft are hardened alloy steel of one piece construction.
  • Special gear design: Non-symmetrical gear insures low noise and compactness.
  • Highest Quality Workmanship.
  • Pressures Up To 3000 P.S.I.
  • Dependable service: Balanced pressure loading insures small dispersion, good durability and maintains high performance.
  • Extremely Efficient.
  • Perfect alignment: "Through bore" design provides perfect alignment of pump element and assures even bearing load.
  • With the aluminum alloy casing, the SP Series features light weight and easy handling.
  • Double pumps: Available in SP20, SP25 and SP25/SP20 Combinations.
  • Maximum speed from 3000 to 4000 RPM using SAE 10W oil.
  • Displacement covers .400 in3/rev. to 3.869 in3/rev.
  • Inlet pressure: Pump inlet should not exceed 5 in. of mercury vacuum or 14 P.S.I. positive pressure.
  • Ports: SAE straight thread O-ring boss for SP20 & SP25. Other Ports available - consult factory. (Taper pipe threads not available.
  • Working oil: A mineral based oil with additives to resist corrosion, oxidation, and foaming is recommended. Viscosity at any running condition should be 60 SUS minimum and 250 SUS maximum. 180o F is the maximum recommended system operating temperature.
  • Filtration: Per ISO cleanliness code level 17/14. As a minimum, 10 micron filtration is recommended.
