ONE

Pump core definition and technical nature





Definition:

The pump core is the core of the Lotion Pump drive system, the mechanical structure of the pump core to generate negative / positive pressure, and realizes the liquid quantitative output and sealing preservation of precision components. Its performance directly determines the experience of using the product (e.g., precision of liquid dispensing, smoothness of pressing, sealing).

Technology Essence

Lotion pump supplier Micro-engineered Mechanical System: Integrated spring mechanics, fluid dynamics, tribology design in the space of 8-25mm in diameter.

Material Interface Science: Solve the compatibility contradiction between glass/metal/plastic/liquid (e.g. alcohol resistance, crystallization resistance)

Lifespan Reliability Engineering: Required to withstand ≥5000 times of pressing test (international standard ISO 22718)




Key Parameters:

- Dispensing volume accuracy: ±0.02g (e.g. 0.5g, 0.5g, 0.5g, 0.5g) 0.02g (e.g. 0.18g/pump) - Starting force: 30-60N (operable range for infants)

- Residue: ≤5% (EU EC 1223/2009 requirement)

TWO

Pump Cartridge Operating Principle

Pump Cartridge Operating Principle (4-stage cycle)



1.Downward stroke

- the presser head pushes the piston rod downward, the main spring is compressed

- the piston seal cuts off the passage between the liquid reservoir and the atmosphere

2.Vacuum formation

- the piston moves downward causing the pump chamber to increase in volume, internal air pressure < bottle air pressure

- the liquid in the bottle opens the bottom valve ball into the pump chamber

3.rebound discharge

- after release the main spring rebound to push the piston upward

- the bottom valve ball closed, the volume of the pump chamber decreases to form a positive pressure

- the liquid top open the piston valve from the nozzle injection

4.Reset Seal

- secondary spring pushes seal closed when piston is reset

- pump chamber is isolated from the outside world to prevent oxidation/volatilization



Precision Control Points:

- Tolerance of ball diameter ≤ 0.03mm (to control opening/closing sensitivity)

- Spring K-value deviation ± 5% (to ensure consistency of liquid discharge)

THREE

Procurement Core Control Elements





Mandatory Terms of the Technical Agreement

90% of Users Have Cognitive Misconceptions


Have you ever encountered such a usage problem: you eagerly open a new bottle of essence, but when pressing the lotion pump, abnormal situations occur — either the material suddenly splashes onto your hands, or the pump head jams and cannot be pressed, making it impossible to dispense the material smoothly?



Faced with such problems, 90% of users usually jump to the conclusion: "This pump head is of unqualified quality and is an inferior product." However, as professional lotion pump supplier and lotion dispenser pump manufacturers with years of experience in the daily chemical packaging field, we need to clarify a key point: in most cases, the pump head itself is not the root cause of the problem; the core contradiction lies in the insufficient compatibility between the pump head and the material. This article will analyze the underlying logic of pump head "malfunction", sort out cognitive misconceptions for you, and provide professional interpretations.



Analysis of the Four Core Causes of Pump Head "Malfunction"

1.Mismatch between Material Viscosity and Pump Core Power (The Most Frequent Factor)

From a basic logical perspective, a low-pressure pump core cannot effectively drive high-viscosity materials, which is similar to "a low-power drive device struggling to move heavy loads". From a technical point of view: products such as face creams or high-viscosity essences need to be equipped with "pump heads specially designed for high-viscosity materials". This type of pump head ensures sufficient driving force by adopting springs with stronger elasticity and piston structures with larger diameters. If a pump for lotion is mistakenly used, the insufficient pump core power will make it impossible to complete the effective material suction and discharge process, leading to material splashing or pump head jamming.



2. Mismatch between Material Fluidity and Suction Tube Caliber

The core logic of this problem can be compared to "a small-caliber pipeline failing to smoothly transport high-viscosity or particle-containing media". The suction tube caliber must be precisely matched to the fluidity and morphological characteristics of the material.

From a technical perspective: if the material contains small particles, highly active precipitates, or is highly viscous, but the matching suction tube inlet has a standard or even small caliber, the material is prone to accumulation and blockage at the inlet of the suction tube. This increases the resistance of material discharge, resulting in poor discharge or sudden pressure-increase splashing. For example, the suction tube caliber suitable for a hand cream pump is different from that of a regular hand lotion pump.



3. Mismatch between Material pH Value and Spring Material

The springs inside ordinary pump heads are mostly made of metal materials, and the acid-base properties of some materials will corrode the metal components — this is a key compatibility issue that is easily overlooked. From a technical point of view: products in categories such as whitening and acid peels (e.g., those containing high concentrations of vitamin C, glycolic acid, salicylic acid, etc.) are usually acidic. If an ordinary metal spring pump head is used, direct contact between the material and the metal spring will accelerate the rusting and corrosion of the spring. This not only increases the pressing resistance of the pump head and eventually causes it to fail, but also may cause metal rust to mix into the material, resulting in product contamination and affecting the safety and stability of use. Professional solution: for acidic, alkaline and other highly corrosive materials, it is necessary to select "all-plastic pump heads" or "external spring pump heads". Through special structural design, complete isolation between the material and metal components is achieved, fundamentally avoiding corrosion problems.



4. Insufficient Compatibility between Material Components and Pump Head Material

Active ingredients such as solvents and oils in some materials will have physical or chemical reactions with the plastic and rubber components of the pump head, leading to the failure of component performance.

From a technical perspective: ingredients such as alcohol, mineral oil, and specific vegetable oils contained in the material may cause swelling, softening or cracking of the PP (polypropylene), PE (polyethylene) material shell and rubber sealing gaskets inside the plastic lotion pump. This directly damages the sealing performance and structural integrity of the pump head, which not only easily leads to liquid leakage, but also causes abnormal pressing resistance due to seal failure, and ultimately results in pump head malfunction. This is also the core reason why "pump head-material compatibility testing" must be carried out during the product R&D stage.



Key Conclusion

There are no absolutely "inferior" pump heads, only mismatched combinations of pump heads and materials. As lotion dispenser pump supplier and plastic lotion pump suppliers, we recommend that during the product R&D stage, you submit material samples to professional packaging suppliers in advance. The technical team will customize the specifications of lotion pumps and treatment pump according to the material parameters, eliminating problems from the source.
