Diaphragm pump LFP6115T series

waterelectricself-priming

Overview
LEFOO LFP6115T 230VAC Demand Delivery Pump for on‑demand water supply. Technical performance data and temperature rise curves are provided for engineering selection and system integration.

Performance data and curves
Test conditions: inlet pressure 0 PSI, ambient and water temperature 25℃, voltage 230VAC 50/60Hz. Test data correspond to 3/8" pipe; results vary with different pipe sizes and ambient conditions.

Temperature rise curve
Measured at ambient 25℃, inlet 0 PSI, working pressure 70 PSI. Motor thermal protector disconnects when housing temperature reaches approximately 73℃ to allow cooling; motor resumes when temperature falls below the reconnection threshold. All curves are approximate and depend on operating conditions.

Performance parameters (Discharge Pressure / PSI — Flow Rate /GPM — Flow Rate /LPM — Current /A)

10 — 1.09 GPM — 4.11 LPM — 0.212 A
20 — 1.04 GPM — 3.93 LPM — 0.227 A
30 — 0.99 GPM — 3.73 LPM — 0.253 A
40 — 0.94 GPM — 3.57 LPM — 0.277 A
50 — 0.91 GPM — 3.43 LPM — 0.301 A
60 — 0.88 GPM — 3.33 LPM — 0.324 A
70 — 0.86 GPM — 3.25 LPM — 0.342 A

Shut-off pressure for selection and related parameters
Common selection reference: Rated voltage 230 V AC; test inlet pressure 0 PSI; typical working flow 1.15 GPM; typical working current ≤ 0.25 A; suction ≥ 2 m; fluid connection 3/8" side female quick connector (NPT 3/8 / threaded).
