How to choose the perfect lotion pump for your product ? This article will analyze the following aspects to help you make a choice.

2- Select Based on Product Viscosity/Fluidity

Usually the brand owner will have specific data on their product’s viscosity and flow rate, this information is often lacking for the lotion pump manufacturer, In this situation, the typical method is to pour the liquid into a beaker and assess its flow characteristics and the surface of the liquid to make a determination.

1. If the liquid’s surface instantly levels out with no trace of marks, all lotion pumps and their variations are suitable. The only consideration then is to select a pump whose materials are compatible with the liquid’s formula.
2. If the liquid’s surface quickly levels out but shows slight stacking marks, you’ll need to verify the spray effect for any spray pumps. Other lotion pumps and their variations should still be suitable.
3. If the liquid’s surface takes 1-2 seconds to level out and shows obvious stacking marks, you should choose a lotion pump with strong suction and a powerful spring. High output pumps are the preferred choice. Another option is to use a airless bottle/jar for packaging.
4. If the liquid’s surface has obvious stacking marks and does not level out quickly, even high output pumps will need to be verified. In this case, your best options are to prioritize using a airless bottle or to opt for a simple cap for packaging.
5. If the liquid does not pour out in a short period of time, you must use a airless system bottle or other packaging formats like a cap, tube, or jar.

3- Select Based on the Material Compatibility Between the Lotion Pump and Product Liquid

Under these conditions, the product must pass a compatibility test, the procedure is as follows:

1. Place the finished product (with liquid already dispensed) in a high-temperature chamber for seven days.
2. After removal, disassemble the product and inspect all parts.
3. The product is considered compliant if there is no cracking, rust, or deformation in the parts, and the liquid shows no discoloration or change in smell.

4- Select Based on the Lotion Pump’s Dosage

Before a product is launched, a consumer survey typically establishes a preliminary recommended usage amount. This recommended amount is then used to select the correct lotion pump. The goal is to choose a pump that can dispense the recommended amount in one or more full pumps.

Generally, the recommended usage is equal to 1-2 times the pump’s dosage.

Par exemple, if the recommended usage is 1.0ml per application, you could choose either a lotion pump with a dosage of 1.0ml per pump or 0.5ml per pump.

5- Select Based on the Final Packing Format

D'abord, confirm the packaging volume. Then, based on that volume and the expected number of uses, you can select the appropriate lotion pump specifications.

Typically, a single package is expected to be used 100 à 300 times.

Example #1: if you’ve chosen a 100ml bottle, you could select a lotion pump with a dosage of:

• 1.0ml per pump, which would last for approximately 100 uses.

• 0.5ml per pump, which would last for approximately 200 uses.

Example #2: if you’ve chosen a 500ml bottle, you could select a lotion pump with a dosage of:

• 2.0ml per pump, which would last for approximately 250 uses.

• 3.5ml per pump, which would last for approximately 140 uses.
