Tubular or Threaded: Tubular or threaded lotion pumps are typically used in applications where the product needs to be released quickly, such as during a shower or while shaving. When using these pumps, it's important to ensure that the tip of the unit is either slightly open or completely closed to allow for quick and efficient release. This feature is most convenient in cold or damp climates where sudden changes in temperature may damage electric devices. A wide range of different types of tubular pumps are available depending on the application and its intended use. Threaded lotion pumps can be used for both wet and dry skin application.
Caps: Many lotion pumps come standard with standard caps that keep liquids inside the bottle. These caps, however, should be regularly cleaned to ensure maximum performance and efficiency. Cleaning the caps ensures that oils and other chemicals are kept from building up within the bottle and causing damage. These caps should also be checked regularly to ensure the lids have no debris stuck in them which may prevent the pump from working properly.
Lotion Pump Types: Depending on the intended application and style, there are two primary categories of pump caps. There are capstalked or threaded caps; and snap-on or semi-permanent caps. Capstalked pumps provide maximum performance by providing two conductors that are threaded on both sides. This allows the motor to run at a higher motor speed for the same stroke volume, which reduces waste and improves lubrication. For this reason, capstalked lotion pumps are commonly found in sports equipment.
Snap-On or Semi-permanent caps are designed to maintain a particular temperature for a longer period of time. Once they reach the melting point of the plastic deformation, the cap breaks off and the remaining portion will rapidly harden to protect the bottle. While this solution provides a more expensive, long-term performance improvement, it does require an extra step to fill the bottle. Rather than opening the bottle directly, a stopper must first be installed to prevent any liquid from penetrating the pump and potentially damaging the actuator. Once the stopper is installed, the lid can be placed on the bottle and the cap snapped on or semi-permanently removed. This process prevents small amounts of melted plastic from entering the mechanism which could reduce the performance of the lanolin pump.
