The LFP1100T is a compact 24V DC diaphragm demand pump designed for clean water delivery and pressure boosting in small OEM water systems. Its dual-chamber diaphragm structure provides reliable water transfer in a space-saving design, making it suitable for equipment with limited installation space.
With a flow rate of up to 1.0 GPM (3.8 L/min) at 0 PSI and a self-priming height of up to 1.5 m, this pump can draw water from a tank and supply it to downstream equipment. Four shut-off pressure options - 30, 40, 50 and 60 PSI - allow OEMs to select the right version according to their water-system requirements.
The pump features a fully enclosed permanent magnet motor, nylon pump housing, EPDM valves, Santoprene diaphragm and stainless-steel spring. A nylon mounting base with vibration-damping feet helps reduce transmitted vibration during operation. Quick-connect inlet and outlet ports simplify installation and assembly.

Select the shut-off pressure according to your system requirement. The LFP1100T series is available in 30, 40, 50, and 60 PSI versions. Please note that the flow rate decreases as discharge pressure increases, so both required flow and working pressure should be considered.
The LFP1100T series is available with preset shut-off pressure configurations. The pump stops when the system reaches the selected shut-off pressure. Please contact LEFOO to confirm the pressure-switch setting required for your system.
This model is specified for clean-water applications with a water temperature range of 5-50°C. Please contact LEFOO before using it with other liquids to confirm material compatibility.
Yes. LEFOO recommends installing the pump after a pre-filter with a filtration rating of at least 50 mesh to help prevent sand and particles from entering the pump.
Yes. LEFOO supports OEM and ODM projects. Please share your required voltage, operating pressure, flow rate, water connection, application, and expected quantity with our sales team.
