A PP screw lock dispenser screw pump is a type of pump designed for dispensing fluids or substances from containers. Here are some common characteristics of a PP screw lock dispenser screw pump:

1. Material: The pump is made from polypropylene (PP), a durable and chemical-resistant thermoplastic material. PP is known for its strength, resistance to corrosion, and suitability for handling a wide range of fluids.

2. Screw Lock Design: The pump is equipped with a screw lock mechanism that securely attaches the pump to the container. This ensures a tight and leak-proof connection, preventing spills or contamination during dispensing.

3. Dispensing Mechanism: The pump utilizes a screw mechanism to draw the fluid from the container and dispense it in a controlled manner. Turning the pump handle or actuator rotates the screw, creating suction and pushing the fluid out of the pump.

4. Pump Size: The size of the pump can vary, with different models available to accommodate different container sizes and applications. Common sizes include 38mm, 40mm, or 45mm pump sizes, but other sizes may be available depending on the specific product.

5. Flow Rate: The pump is designed to provide a specific flow rate for dispensing fluids. The flow rate can vary depending on factors such as the viscosity of the fluid, the pump design, and the pumping action applied.

6. Compatibility: The PP screw lock dispenser screw pump is compatible with a wide range of fluids, including liquids, chemicals, detergents, soaps, and more. However, it's important to check the compatibility of the pump with the specific fluid being dispensed to ensure proper functioning and chemical resistance.

7. Adjustable Dosage: Some models of screw pumps may offer adjustable dosage control, allowing users to adjust the amount of fluid dispensed with each pump action. This feature provides flexibility in dispensing different volumes as needed.

8. Easy to Use: The pump is designed for easy operation, typically requiring a simple hand-operated pumping action. It can be easily operated by pressing or rotating the pump handle or actuator.

9. Easy Installation: The PP screw lock dispenser screw pump is designed for easy installation on containers. The screw lock mechanism securely attaches the pump to the container neck, and installation typically involves screwing the pump onto the container opening.

10. Chemical Resistance: PP material provides excellent chemical resistance, making the pump suitable for dispensing a wide range of fluids, including aggressive chemicals, acids, alkalis, and solvents. This ensures the pump's durability and longevity in various environments.
