The LRS-15 household automatic circulation pump mainly addresses two major issues: Firstly, as a hot water circulation pump, it connects with the water heater to achieve instant heating upon activation, eliminating the need for waiting and avoiding waste of cold water. Secondly, as a water pressure booster pump, it boosts the pressure of the entire household pipes, improving the water flow and pressure of faucets, taps, etc. The core feature is that it can automatically start and stop based on water flow, temperature or pressure.

OGGIN Automatic Circulation Pump 

The automatic circulation pump is driven by an electric motor that continuously rotates the impeller, propelling the liquid to achieve autonomous circulation. Its core function is to maintain uniform and stable liquid flow within the system, making it widely applicable in various scenarios requiring precise control of flow rate, pressure, or temperature.

Advantages of Circulation Pump

  • Automatic Mode -Automatically opens when water flow starts and closes when water flow stops

  • Quiet Design - Features a shielded structure for low-noise operation, ideal for home use

  • Material Options - Pump head available in cast iron, cast brass, or stainless steel

  • Safety Protection - Maintains continuous circulation in hot water pipes to inhibit bacterial growth

  • Energy-Saving & Water - Conserving: Drains cold water from pipes before use, minimizing cold water waste.

Application Fields


1. Hot Water Circulation System

As the core equipment enabling a “zero-cold-water” experience, it actively recirculates cooled water from hot water pipes back to the water heater for reheating. This ensures precise delivery of continuous hot water to any tap in your home the moment it's turned on, completely eliminating the hassle of waiting for hot water and preventing cold water waste.


2. Heating System

Serving as the “powerhouse” for radiator or underfloor heating systems, it efficiently drives forced circulation of hot water between the wall-mounted boiler and heat emitters (radiators or underfloor heating pipes). This rapidly and evenly distributes warmth throughout every room, ensuring uniform whole-house heating and maintaining stable, high-efficiency system operation.


3. Water System Maintenance

Provides robust circulation power for residential solar water heating systems, heated swimming pools, ornamental fish ponds, and similar applications. Ensures continuous flow of water or heat transfer media, effectively maintaining constant system temperatures and preserving water clarity while guaranteeing efficient heat exchange. This comprehensive support safeguards the stable operation of specialized water systems.


4. Whole-House Water Purification System

Provides stable and sufficient water pressure for whole-house water treatment equipment like central water softeners and purifiers. Effectively overcomes head loss inherent in such devices, ensuring deeply treated softened or purified water reaches every household tap with consistent, robust pressure. This guarantees long-term, high-efficiency operation of the entire water treatment system.
