Diaphragm pump LFP0150T series

waterDCnormal priming

Overview
The LFP0150T is a 12 V DC demand delivery pump designed for on‑demand fluid supply in industrial and mobile systems. Performance data are measured at 0 PSI inlet pressure, ambient and water temperature of 25℃, and using a 3/8" pipe; results may vary with other conditions or pipe sizes.

Performance data and curves
Test conditions: inlet pressure 0 PSI, ambient 25℃, water 25℃, voltage 12 V DC. Temperature rise curve measured at ambient 25℃, inlet 0 PSI and working pressure 70 PSI. A thermal protector interrupts power when housing temperature reaches approximately 73℃ to protect the motor; it reconnects after cooling. All curves are indicative and depend on installation and ambient conditions.
