Description
The SongLong SL-387 Submersible Water Pump is an essential cooling accessory for water-cooled PCP airgun compressors. Designed to circulate cooling water through the compressor head, it helps maintain stable operating temperatures during high-pressure filling of PCP air rifles, buddy bottles, and carbon fibre cylinders.
With a maximum flow rate of 500 litres per hour, this compact 8 W pump provides continuous coolant circulation, reducing heat build-up and helping protect seals, piston rings, and other internal compressor components. It is widely suited to water-cooled PCP compressors such as Yong Heng, GX, Tuxing, and similar 300 Bar / 4500 PSI systems that rely on an external water reservoir. Pumps in this performance class are commonly used for aquarium circulation and DIY water-cooling applications because of their compact size and continuous-duty operation
