Performance data are measured with flooded inlet (0 PSI), water temperature at 21°C, and 24 VDC power supply. Positive inlet pressure increases discharge pressure proportionally. Maximum inlet pressure: 60 PSI.
Thermal behavior (Heat Rise)
The Heat Rise graph shows the increase in motor surface temperature over time as a function of current draw.
The motor is equipped with an integrated thermal protector that automatically shuts off the pump when the motor surface temperature reaches approximately 63°C (145°F).
Continuous operation is possible within the defined current limits. At higher loads, the pump requires intermittent operation cycles to allow motor cooling.
Dimensional drawings
Dimensional drawings allow correct mechanical integration of the pump within the system. Dimensions are expressed in millimeters (mm).
