Overview
The LEFOO LFP1150T is a 24 V DC diaphragm booster (demand delivery) pump for on‑demand water delivery and pressure maintenance in low‑flow applications. Test data and curves are provided to support engineering selection and system integration.

Performance data and curves
Test conditions: inlet pressure 0 PSI, ambient 25℃, water 25℃, voltage 24 V DC; test pipe 3/8" (results vary with other pipe sizes). Performance (Discharge Pressure / PSI | Flow Rate / GPM | Flow Rate / LPM | Current / A):
0 | 1.50 GPM | 5.68 LPM | 2.00 A
10 | 1.46 GPM | 5.53 LPM | 2.11 A
20 | 1.42 GPM | 5.38 LPM | 2.40 A
30 | 1.38 GPM | 5.24 LPM | 2.69 A
40 | 1.34 GPM | 5.09 LPM | 2.98 A
50 | 1.31 GPM | 4.98 LPM | 3.30 A
60 | 1.27 GPM | 4.79 LPM | 3.56 A
70 | 1.23 GPM | 4.65 LPM | 3.90 A

Temperature rise curve
Temperature rise measured at ambient 25℃, inlet 0 PSI, working pressure 70 PSI. To protect the motor, a thermal protector disconnects power when housing temperature rises to approximately 73℃; motor restarts when temperature falls below the reset threshold. Curves are approximate and depend on ambient and piping conditions.

Shut-off pressure for selection
Available model variants and selection data (model | rated voltage | inlet pressure | working flow | working current | suction | shut-off pressure | max current | connection):
LFP1150T-30070 | 24 V DC | 0 PSI | 1.50 GPM | ≤ 2.3 A | ≥ 2 m | 70 PSI | ≤ 4.3 A | 3/8" side female quick connector (NPT 3/8, screw thread)
LFP1150T-30060 | 24 V DC | 0 PSI | 1.50 GPM | ≤ 2.3 A | ≥ 2 m | 60 PSI | ≤ 4.0 A | 3/8" side female quick connector
LFP1150T-30050 | 24 V DC | 0 PSI | 1.50 GPM | ≤ 2.3 A | ≥ 2 m | 50 PSI | ≤ 3.7 A | 3/8" side female quick connector
LFP1150T-30040 | 24 V DC | 0 PSI | 1.50 GPM | ≤ 2.3 A | ≥ 2 m | 40 PSI | ≤ 3.4 A | 3/8" side female quick connector
LFP1150T-30030 | 24 V DC | 0 PSI | 1.50 GPM | ≤ 2.3 A | ≥ 2 m | 30 PSI | ≤ 3.1 A | 3/8" side female quick connector
