12V Submersible Water Pump DC Fountain Pump UltraQuiet Brushless Mini Fish Tank Hydroponics Use

Compact, quiet, and durable 12V DC water pump designed for submersible and inline liquid transfer. The pump combines a ceramic shaft and static sealing to minimize leakage risk, runs quietly at under 40 dB, and delivers a steady 240 L per hour flow in a small, lightweight package. Key benefits Leakresistant shaft and seal: ceramic shaft plus static seal design reduces wear and avoids common dynamic seal leakage. Quiet operation: noise under 40 dB keeps workspaces comfortable and reduces disturbance during sampling or continuous transfer. Compact and lightweight: small footprint and low weight make installation and integration easy in tight spaces. Long service life: rated lifetime 20000 hours, with reported operational longevity exceeding 30000 hours under suitable conditions. Versatile installation: amphibious design allows submersible installation or inline mounting for flexible use. Main features and specifications Dimensions: 55 mm (L) x 34 mm (W) x 41 mm (H) Rated voltage: 12V DC Rated current: 400 mA Power consumption: 4.8 W Flow rate: 240 L per hour Noise level: less than 40 dB Lifetime: 20000 hours (rated) Shaft material: ceramic Seal type: static seal, nondynamic Inlet diameter: 8 mm Outlet diameter: 8 mm Weight: 65 g Package includes: 1 water pump Practical application scenarios Sewage sampling and smallscale wastewater monitoring: submersible capability and leakresistant sealing make the pump suitable for collecting samples from tanks or pits with minimal maintenance. Liquid transfer and recirculation in equipment or test rigs: compact size and steady 240 L per hour flow support continuous transfer in confined systems. Quiet workplace installations: low noise output is suitable for laboratories, offices, or workshops where reduced acoustic impact is important. Why this pump solves common problems Prevents leakage: the ceramic shaft plus static seal lowers the chance of leaks compared to dynamic seal designs. Saves space and simplifies installation: small dimensions and light weight allow mounting where larger pumps will not fit. Reliable for long deployments: rated lifetime and robust shaft construction reduce downtime and maintenance needs. What is included 1 water pump This unit is intended for liquid transfer, sampling, and submersible applications requiring compact size, low noise, and reduced leakage risk.
