Diaphragm pump LFP0075T series

waterDCself-priming

Performance data and curves
Data were tested at inlet pressure of 0 PSI, ambient temperature and water temperature of 25℃, and voltage of 12V DC. Test results refer to a 3/8" pipe; using other pipe sizes will change the results.

Performance parameters
Discharge Pressure (PSI) | Flow Rate (GPM) | Flow Rate (LPM) | Current (A)
0 | 0.75 | 2.84 | 1.20
10 | 0.71 | 2.70 | 1.49
20 | 0.68 | 2.56 | 1.79
30 | 0.64 | 2.41 | 2.07
40 | 0.60 | 2.27 | 2.36
50 | 0.56 | 2.13 | 2.65
60 | 0.51 | 1.92 | 2.93
70 | 0.48 | 1.81 | 3.22

Temperature rise curve
The temperature rise curve was measured at ambient 25℃, inlet pressure 0 PSI and working pressure 70 PSI. To protect the motor, the housing thermal protector disconnects when temperature reaches approximately 73℃; motor operation resumes after cooling. All performance and temperature data are approximate and will vary with installation, fluid type and ambient conditions.
