General Notes
-
All pressure values are for unidirectional pumps; for reversible pumps, the maximum pressures are 15% lower than the values listed above. Pressure units follow international general standards, and 1 bar is equivalent to approximately 14.5 psi for easy conversion and application.
-
The pumps feature high volumetric efficiency and hydro-mechanical efficiency, ensuring stable performance under arduous operating conditions. The two-piece compact construction allows for flexible integration in limited installation space.
-
Mounting flanges, shafts and ports can be customized according to SAE, European or ISO standards to meet specific application needs. Inlet and outlet ports are available in Italian flange type as standard.
-
It is recommended to use CASAPPA original filters to maintain the required contamination class and extend the pump’s service life. The pump’s service life can be further prolonged by ensuring proper fluid temperature and viscosity control, with the recommended viscosity range consistent with common hydraulic system requirements.
-
The rotation direction is determined by viewing the drive shaft; counterclockwise (CCW) rotation is also available as an optional configuration.
