We have specially optimized the sealing structure of the Leak-Proof Liquid Pump. The PP plastic pump body is paired with high-quality sealing rings, providing dual guarantees for the sealing effect. It truly ensures no leakage when inverted or shaken. Whether during long-distance transportation with the bottle tilted or shaken, or when carried in a bag and squeezed, there will be no leakage. This effectively prevents liquid evaporation and contamination. At the same time, it avoids leakage from dirtying clothes, luggage, or tabletops. This super-strong sealing design solves the industry problem of leakage from ordinary pump heads, making the storage, transportation, and carrying of liquids more secure.
Our Leak-Proof Liquid Pump has extremely strong versatility. It can be applied in multiple fields such as beauty care, household cleaning, and food hygiene, and is compatible with various low and medium viscosity liquids, such as toners and lotions in the beauty sector, detergents and disinfectants in the household cleaning sector, and fruit and vegetable cleaners in the food hygiene sector. Whether for daily household use, commercial batch applications, long-distance transportation, travel carrying, or daily storage, it can stably perform the leak-proof function, with wide applicability and strong practicality.
Our pump cores are designed with high-quality structure, featuring smooth rebound, light and effortless pressing, and automatic restoration to the original position after release, requiring no excessive force. Daily use is more convenient. After rigorous testing, even with long-term and high-frequency pressing of Leak-Proof Liquid Pump, there will be no problems such as stalling, no liquid output, or leakage. They are highly durable and suitable for both household daily use and commercial high-frequency applications. Additionally, the precise quantitative design not only avoids waste but also makes the usage more standardized, especially suitable for scenarios requiring a fixed dosage.
When installing the Leak-Proof Liquid Pump, align the threaded interface of the pump head with the bottle opening and tighten it clockwise to ensure a complete seal with no loose gaps. Before the first use, press the pump head 3 to 6 times to expel the internal air until the liquid flows smoothly. During use, gently press the top of the pump head vertically to achieve quantitative liquid output. Press as needed without excessive force to avoid damaging the pump core. After daily use, wipe the liquid outlet with a clean cloth to prevent liquid residue. If the liquid output is not smooth, rinse the pump head inside with clean water. Be careful not to remove the sealing ring to avoid damaging the sealing structure and affecting the leak prevention effect.
As a professional Manufacturer and Factory, Ruijiong has always prioritized both quality and environmental protection, and strictly implements a full-process quality control system. When raw materials enter the factory, they undergo rigorous testing to ensure compliance with relevant standards; during the production process, on-site inspections are conducted in real time to promptly identify production hazards; before each batch of products leaves the factory, key indicators such as sealing performance and liquid output accuracy are tested one by one to ensure uniform quality and stable performance. Ruijiong relies on an automated production line to achieve large-scale stable production, with delivery times consistently within 30-35 days, which can meet the bulk purchasing needs of customers. At the same time, we offer 3-5 free samples to facilitate customers' testing and evaluation of the product's performance and compatibility.
Answer: Yes, we offer 3 to 5 samples for free. This is to facilitate customers in testing the sealing performance, liquid discharge effect and compatibility of the bottle body of the product.
Answer: The delivery cycle for regular mass production is 30 to 35 days. We will strictly control the production schedule to ensure timely delivery and prevent any delay in customer usage.
Answer: First, rinse the inside of the Leak-Proof Liquid Pump with clean water to remove the remaining liquid. Be careful not to disassemble the sealing ring, as doing so may damage the sealing structure and affect the leak-proof effect.
