Yo, folks! As a supplier of plastic lotion pumps, I often get asked this question: "Can I use a plastic lotion pump for thick lotions?" Well, let's dive right into it and break it down.
First off, let's talk about what makes a lotion thick. Thick lotions usually have a high viscosity, which means they don't flow as easily as thinner liquids. This could be due to the presence of ingredients like shea butter, beeswax, or high - molecular - weight polymers. These substances give the lotion its rich, creamy texture, but they also pose a challenge when it comes to dispensing.
Now, plastic lotion pumps are designed to work with a range of product viscosities. But not all pumps are created equal. Some are better suited for thick lotions than others. For instance, our 28 400 Pump Dispenser is a great option for thicker formulations. It has a larger orifice and a more robust pumping mechanism that can handle the extra resistance from thick lotions. This pump is engineered to push the thick product up the dip tube and out of the nozzle with relative ease.
Another option is our Hand Cream Pump Dispenser. Hand creams are often thick, and this pump is specifically designed to deal with that. It has a well - calibrated piston and spring system that can generate enough force to dispense the thick hand cream in a controlled manner. You won't have to worry about the lotion getting stuck in the pump or coming out in an uneven stream.
But how do you know if a plastic lotion pump will work for your thick lotion? There are a few factors to consider.
Viscosity Measurement
The first thing is to measure the viscosity of your lotion. You can use a viscometer, which is a device that measures the resistance of a fluid to flow. Once you know the viscosity, you can compare it with the specifications provided by the pump manufacturer. Most of our pumps have a recommended viscosity range. If your lotion falls within that range, then chances are the pump will work just fine.
Dip Tube Diameter
The diameter of the dip tube also matters. A wider dip tube allows thick lotions to flow more easily. Our Plastic Lotion Pump comes with different dip tube options. You can choose a wider dip tube if you're dealing with a very thick lotion. This helps to reduce the friction between the lotion and the tube walls, making it easier for the product to be drawn up into the pump.
Nozzle Design
The design of the nozzle is crucial as well. A nozzle with a larger opening can prevent clogging. Thick lotions are more likely to clog a small - sized nozzle. Our pumps are designed with nozzles that are optimized for different viscosities. For thick lotions, we offer nozzles with a wider opening to ensure a smooth and consistent dispense.
Pumping Force
The amount of force required to operate the pump is another important consideration. Thick lotions need more force to be dispensed. Our pumps are designed to be ergonomic, so they can be easily operated even when dealing with thick products. The spring and piston mechanism in our pumps are calibrated to provide the right amount of force to push the thick lotion out.
However, there are some limitations. If your lotion is extremely thick, like a paste - like consistency, even the best - designed plastic lotion pump might struggle. In such cases, you might need to consider alternative dispensing methods, such as a squeeze tube or a jar with a spatula.
But for most thick lotions that are commonly found in the market, like body butters, rich moisturizers, and some hair creams, our plastic lotion pumps work great. They offer a convenient and hygienic way to dispense the product. You don't have to dip your fingers into the container, which can contaminate the lotion.
One of the advantages of using plastic lotion pumps is that they are cost - effective. Plastic is a relatively inexpensive material compared to other options like glass or metal. This means you can keep your production costs down without sacrificing quality.
Another benefit is that plastic is lightweight. This is especially important if you're shipping your products. Lighter packaging means lower shipping costs. And let's not forget about the environmental aspect. Many of our plastic lotion pumps are made from recyclable materials, so you can do your part for the planet.
