The 175QJP series is a premium professional fountain submersible pump specifically engineered for high-performance water displays and music fountains. Featuring a high-quality cold-rolled silicon steel motor core, this pump delivers exceptional energy efficiency and superior magnetic conductivity, ensuring stable operation even under frequent start-stop cycles without overheating.
Designed for durability in aquatic environments, the 175QJP utilizes a water-lubricated alloy copper sleeve and stainless steel components instead of traditional ball bearings. This innovative design eliminates the risk of rust and oil deficiency, significantly extending the motor's lifespan and reducing maintenance costs for large-scale water feature projects.

Frequently Asked Questions
It is specifically optimized for music fountains and decorative water features, though it is also highly effective for deep well water intake, agricultural irrigation, and high-rise water supply.
Water-lubricated alloy copper sleeves eliminate the need for grease, preventing the common problems of bearing rust and oil leakage, which leads to a longer operational life in submersible conditions.
No. The 175QJP must be installed strictly in a vertical position. Horizontal or upside-down installation will damage the motor and pump components.
In freezing temperatures, all water must be drained from the motor cavity to prevent ice damage. Store the unit in a non-corrosive environment below 40°C.
To prevent the pump from sucking in mud or sediment, the distance from the pump base to the bottom of the well should be no less than 3 meters.
Yes. While the standard model is 380V/50Hz, we provide customization services for other voltage grades to meet specific international power requirements.
