AP212 gear pumps are widely used in modern hydraulic systems due to their high performance, long service life and low purchase and maintenance costs. The AP212 series is able to achieve high operating pressures, excellent volumetric and mechanical efficiency.
Standard Features:
- Displacement range .269 to 1.599 in3/rev
- New generation optimized and standardized balancing blocks
- New gears profile (12 teeth) with increased transmissible torque
- Design and materials that guarantee excellent technical specifications and long life service
- Recommend using only mineral oil-based hydraulic fluids that comply with the ISO/DIN standards
- Buna N Seals
Viscosity Range:
- Recommended 20 + 120 mm2/s (cSt)
- Permitted up to 700 mm2/s (cSt)
Operating Temperature:
- 5° to 176°F (-15 to 80°C)
Suction:
- Absolute suction pressure must be 11 PSI
- It is also advisable to choose a filter of a suitable size to minimize any pressure drop and to take measures to prevent gradual clogging over time
Caution:
- Not to be used with Water Glycol
- The coupling joint must be able to absorb any discrepancies in the coaxial alignment of the
motor-pump shafts without placing any load on the pump shaft - Absolutely no radial or axial forces should be transmitted to the drive shaft in the motorpump
coupling - Such forces cause rapid and irregular wear on the balancing surface of the bushings and gear support, with a consequent worsening in pump performance
