OGGIN PHJ Series Self-priming Pump
Self-priming pumps are the finest offspring of centrifugal pumps, requiring no pre-filling with water—they start pumping immediately upon activation. They automatically expel air from the suction line, enabling seamless “dry start” operation. This ingenious design eliminates the need for the traditional foot valve found in conventional centrifugal pumps, dispensing with the tedious process of repeated water filling. This streamlines the operation, significantly enhancing the convenience and practical appeal of pumping equipment.

Advantages of Self-priming Pump
Self-priming capability -with a self-priming lift of up to 8 meters, it can draw water from low-lying areas beneath the pump body, providing pressurized water supply for high-rise buildings.
Versatile Applications - Capable of handling clean water, liquids containing particles, or mildly corrosive media.
Adaptable to Complex Conditions - Requires minimal pipeline sealing, suitable for field operations or temporary drainage needs.
Compact and Energy-Efficient - Features a compact design with minimal space requirements and high energy efficiency.
Easy Installation - Can be mounted above the liquid level, facilitating simple routine maintenance.
Product Selection
Application Fields
1. Water Tower Supply System
The PHJ self-priming pump is securely positioned on the ground, drawing clean water from underground sources via suction pipes. After undergoing pressure boosting, the water is smoothly transported to elevated water towers or storage tanks for proper retention. Its integrated pressurization device acts as a loyal guardian, ensuring a steady and continuous supply of tap water.
2. Residential Applications
The PHJ self-priming pump, also known as a household booster pump, excels at enhancing water pressure and enabling hot water circulation. It efficiently resolves the issue of weak shower flow caused by insufficient water pressure in high-rise residences. Compact, quiet, and easy to install, it brings significant convenience to household water use.
3. Agricultural Irrigation Sector
The PHJ self-priming pump serves as an indispensable “helper” for small to medium-sized farmland irrigation. It can directly draw water from rivers, ponds, or wells to perform sprinkler irrigation. Its adaptability to varying water source locations, ease of mobility, and straightforward operation make it particularly suited for irrigating fragmented farmland.
4. Commercial and Building Applications
PHJ self-priming pumps are widely used in auxiliary water supply systems for commercial and public facilities. They excel in scenarios such as rainwater drainage from basement sump pits, pressure boosting for underground water tanks, and makeup water circulation for central air conditioning cooling towers.
