Specification notes:

4.
Duty dependent. For operation above 122 °F (50 °C) or below 32 °F (0 °C) consult First Sensor.
Noise is dependent on the configuration and operation of the pump in the application.
Life rating can vary depending on application and operating conditions.
Current range is dependent on motor type, voltage, pressure/vacuum and flow requirement. Lower levels possible depending on
application.
5. Inductance is an indicator of induced voltage with change in current and it is a key parameter to enable customers’ low energy
intrinsic safety systems.
6. Maximum intermittent pressure/vacuum data is a pump capability guideline for applications that go beyond the maximum continuous
levels for short periods of time. Please consult customer specific requirements with First Sensor.
7. Pump efficiency is a measure of the flow rate generated per unit of power consumed. Efficiency may change dependent on
application and operating condition at free flow.
Important:
·
·
·
·
It is not recommended to run the pump continuously, 100% duty cycle, at higher than 2 psig.
The pump flow and pressure can be controlled by adjusting the input voltage from zero to maximum rated voltage.
The pump is not a pressure holding device. An external check valve is recommended if there is a pressure holding requirement.
Pump orientation does not affect performance or life.
