The Xinjitai XB187-20 Mechanical Spray Pump is a high-precision dispensing mechanism specifically engineered for nasal spray applications. Constructed from durable, chemically resistant Polypropylene (PP) and Polyethylene (PE), this sprayer ensures long-term reliability when in contact with various aqueous or alcoholic-based formulations. Its primary function is to deliver a consistent, fine mist of medication or saline solution directly into the nasal cavity, facilitating effective treatment for conditions such as allergic rhinitis, sinus congestion, dryness, or viral infections. The design features a standard 20mm actuator and a compatible nozzle that optimizes particle size distribution, ensuring maximum absorption through the nasal mucosa while minimizing wastage.
This mechanical pump operates via a simple push-down action, triggering an internal piston mechanism that draws liquid from the bottle and atomizes it upon release. The integration of PP and PE materials guarantees excellent resistance to corrosion from active pharmaceutical ingredients, preserving product integrity over time. The unit is designed to fit standard 20mm neck finishes on PET or HDPE bottles commonly used in the pharmaceutical and personal care industries.
Users should observe several critical precautions during handling and operation. First, ensure the pump is primed before initial use by pumping several times until a fine mist appears; this prevents air pockets that could compromise dosage accuracy. Avoid exposing the device to extreme temperatures, which may deform the plastic components or affect the spring tension. Do not disassemble the pump, as this can damage the precision seals and lead to leakage or inconsistent spray patterns. Furthermore, keep the nozzle clean and free from debris to prevent bacterial contamination, especially since nasal sprays are used internally. Always store the assembled unit upright to maintain seal integrity and prevent clogging. For optimal performance, use only compatible solvents and avoid harsh chemicals that might degrade the polymer structure. Proper maintenance and adherence to these guidelines will ensure the XB187-20 delivers safe, accurate, and reliable therapeutic results for end-users.
