How is the dispensing volume of a All Plastic Treatment Pumps determined, and can it be adjusted?

2024.06.17

The dispensing volume of all-plastic treatment pumps, like those used for lotions, creams, or other liquid products, is primarily determined by the design and specifications of the pump. It is not typically adjustable by end-users once the pump is manufactured. Here's how the dispensing volume is determined:
Pump Design: The dispensing volume is primarily determined during the design and manufacturing process of the treatment pump. The pump's internal components, such as the piston, spring, and valve systems, are engineered to deliver a specific volume of product with each pump actuation.
Piston Size and Stroke Length: The size of the piston and the length of its stroke are key factors in determining the volume dispensed. A larger piston size and longer stroke will typically dispense a larger volume of product per pump.
Spring Tension: The tension of the spring inside the pump affects the force applied to the piston. A stronger spring will typically dispense a larger volume, while a weaker spring will dispense a smaller volume.
Valve System: The valve system within the pump controls the flow of product during dispensing. It opens to allow product to flow into the pump chamber and then closes to prevent backflow. The design and specifications of the valve system can impact the volume dispensed.
Nozzle Size: The size of the nozzle or orifice through which the product is dispensed also affects the volume. A larger nozzle will allow more product to flow, while a smaller one restricts the flow.
Actuation Force: The force applied by the user when pressing down on the pump head can also influence the volume dispensed. A harder press may result in more product being dispensed.
Consistency in Manufacturing: Precise manufacturing processes are essential to ensure consistency in the dispensing volume across multiple units of the same pump design.
Quality Control: Quality control measures are in place during production to ensure that each pump dispenses the specified volume accurately.
While the dispensing volume is typically fixed during manufacturing, it is possible for manufacturers to offer different pump options with varying dispensing volumes to meet the needs of different products. For example, a manufacturer may offer pumps with different piston sizes, springs, or nozzle sizes to accommodate a range of viscosities and desired dispensing volumes.
If you need a specific dispensing volume for your product, it's advisable to work closely with the All Plastic Treatment Pumps Manufacturers to select a pump design that aligns with your requirements. However, once the pump is manufactured and in use, end-users usually cannot adjust the dispensing volume themselves. Any adjustments or modifications would typically require changes to the pump's internal components, which should be done by the manufacturer or a trained technician to maintain product quality and consistency.
