As a supplier of plastic lotion pumps, I understand the frustration that comes with a pump that won't dispense. It's a common issue that can happen to anyone, and it can be quite annoying when you're in a hurry to use your favorite lotion or soap. In this blog post, I'll share some troubleshooting tips to help you get your plastic lotion pump working again.
1. Check for Blockages
The most common reason a plastic lotion pump won't dispense is a blockage in the pump mechanism or the dip tube. Blockages can occur due to dried product, debris, or even the product itself thickening over time.
Inspect the Nozzle
Start by examining the nozzle of the pump. Look for any visible signs of dried product or debris. If you see any, you can try to clean it with a small pin or a toothpick. Gently insert the pin or toothpick into the nozzle opening and carefully remove any blockages. Be careful not to damage the nozzle or push the blockage further into the pump.
Check the Dip Tube
The dip tube is the long tube that extends into the bottle and draws the product up into the pump. Sometimes, the dip tube can become clogged or kinked, preventing the product from flowing properly. To check the dip tube, remove the pump from the bottle and inspect the tube. If it's clogged, you can try to clean it by soaking it in warm, soapy water for a few hours. Then, rinse it thoroughly and reattach it to the pump. If the dip tube is kinked, try to straighten it out gently.
2. Prime the Pump
If the pump is new or has been sitting unused for a long time, it may need to be primed. Priming the pump helps to remove any air from the system and allows the product to flow freely.
Steps to Prime the Pump
- Remove the cap from the bottle and make sure the pump is attached securely.
- Hold the bottle upright and press down on the pump firmly several times. You may need to press down 5 - 10 times before the product starts to dispense.
- If the product still doesn't dispense, try turning the bottle upside down and pressing the pump a few more times. This can help to dislodge any air bubbles that may be trapped in the pump.
3. Check the Product Consistency
The consistency of the product can also affect the performance of the pump. If the product is too thick, it may not flow through the pump easily. On the other hand, if the product is too thin, it may leak or not dispense properly.
Adjusting the Product Consistency
If the product is too thick, you can try thinning it out by adding a small amount of water or a compatible thinner. Stir the product well to ensure that the thinner is evenly distributed. If the product is too thin, you can try thickening it by adding a small amount of a thickening agent, such as xanthan gum or carbomer. Again, stir the product well to ensure that the thickening agent is fully dissolved.
4. Examine the Pump Components
Over time, the components of the pump can wear out or become damaged, causing it to malfunction. Here are some components to check:
Spring
The spring inside the pump is responsible for returning the pump to its original position after each use. If the spring is broken or damaged, the pump may not work properly. To check the spring, remove the pump from the bottle and disassemble it carefully. Inspect the spring for any signs of damage, such as rust or breakage. If the spring is damaged, you may need to replace it with a new one.
Pistons and Seals
The pistons and seals inside the pump help to create a vacuum that draws the product up into the pump. If these components are worn out or damaged, the pump may not be able to create a proper vacuum, resulting in poor dispensing. To check the pistons and seals, disassemble the pump and inspect them for any signs of wear or damage. If necessary, replace the pistons and seals with new ones.
5. Contact the Manufacturer
If you've tried all of the above troubleshooting steps and the pump still won't dispense, it may be a manufacturing defect. In this case, it's best to contact the manufacturer for further assistance.
