This article explores the functional testing methods for lotion pumps, covering pump classifications, operating principles, compatibility, and key testing standards.
· Screw Pumps: Open via a twisting motion.
· Snap Pumps: Feature a locking mechanism.
· Push-Button Pumps: Similar to spray guns.
· Direct Press Pumps with Covers: Designed for direct use.
· Locking Push Pumps with Covers: Offer additional protection.
These designs cater to various needs; for instance, push-button pumps are typically used for cleaning products like degreasers and glass cleaners.
· Lotion Pumps: Ideal for viscous products.
· Foam Pumps: Create foam for hand soaps and baby products.
· Vacuum Pumps: Prevent air exposure, suitable for high-preservation products.
· Spray Pumps: Produce mist for toners and perfumes.
· Aerosol Pumps: Utilize pressure to create a mist for shaving foams and hair sprays.
· Lotion Pump: Operates with a small piston system. When pressed, the spring compresses, pushing the product out; releasing it creates a vacuum to draw in more product.
· Vacuum Pump: Uses a pressure differential with a small hole at the bottle's bottom, allowing the internal piston to rise and dispense product without a straw.
· Foam Pump: Mixes the product with air to create foam upon dispensing.
· Spray Pump: Creates a mist by mixing liquid and air through a nozzle.
· Aerosol Pump: Relies on internal pressure to spray product as a mist.
· Sealing of the Spring and Glass (or Steel) Ball: Affects the force with which the product rises; poor sealing can lead to leaks.
· Sealing Ring at the Top of the Valve Body: Ensures suction strength is maintained when the pump is released.

Testing is crucial to ensure pump quality and user satisfaction. Common testing items include:
· Leak Testing: Ensures the pump does not leak during transport or storage.
· Dispensing Consistency: Tests the response speed, typically stabilizing within 2-5 presses.
· Dispensed Volume: Weighing tests to confirm that dispensing meets design standards.
· Rebound Speed: Should complete within three seconds.
· Drop Testing: Evaluates durability after a 1.2-meter drop.
· Heat and Cold Resistance: Verifies stability at extreme temperatures (48°C and -15°C) over 24 hours.
· Fatigue Testing: Assesses durability through repeated use until the product is exhausted.
