Mini diaphragm submersible water pump — models FL41 and FL43. Designed for compact, reliable water transfer with mains AC compatibility and strong lift capability. Key benefits Compact mini design fits tight spaces where larger pumps cannot. Diaphragm mechanism provides steady pressure for shortdistance transfer and boosting tasks. Submersible construction allows use inside tanks, sumps or small wells for discreet installation. AC 110V / 220V compatibility (FL43 available in 220V) lets you choose the correct mains voltage for your region. 40 psi maximum pressure and up to 25 m head deliver meaningful lift and pressure for many smallscale applications. Key attributes Models: FL41, FL43 (FL43 220V available) Voltage: AC 110V / 220V (confirm model before ) Pump type: Electric mini diaphragm pump Function: Submersible water pump for lifting and pressurizing water Maximum pressure: 40 psi Maximum head: 25 m Size: Mini / compact form factor suitable for limitedspace installations Performance focus: Pressure delivery and head lift rather than largevolume industrial transfer Typical applications Garden and small irrigation systems: Boost pressure and lift water from tanks or cisterns to sprinklers, drip lines, or hoses. Fountains, ponds and water features: Submersible installation for discreet operation and reliable circulation. Domestic water transfer and boosting: Move water between containers, support small household pressure needs, or provide backup water transfer in remote or temporary setups. Installation and compatibility notes Confirm the model voltage before installation; FL43 is available in a 220V variant. Designed for submersible use; select a mounting location that keeps the pump submerged and of heavy debris. Suitable for AC mains supply at the indicated voltage; verify local power compatibility before connecting. Why customers choose FL41 / FL43 Straightforward submersible solution when space is limited and reliable lift is required. Clear electrical options for different regions with both 110V and 220V availability. Provides consistent pressure up to 40 psi and lift up to 25 m, making it a practical choice for many residential and light commercial water tasks. Check model and voltage on the product label before ordering to ensure correct compatibility with your installation.
