If you are starting out making syrup, you will need a good quality Syrup Dispenser Pump. Look for an aluminum or stainless steel dispenser pump, since these tend to be larger, heavier, and tend to have a longer life span than other materials. If you are using an older model, you might want to consider changing it out altogether. If you are working with an older machine, you may also want to look at buying a used Syrup Dispenser Pump. There are many quality machines on the market, but used ones can be had for only a few dollars. Many companies deal in used machines, simply because they are more cost effective and do not take up too much storage space.
Once you have decided on your Syrup Dispenser Pump, it is time to get to work. Pour the desired amount of syrup (approximate) into the dispenser, turn it on, and allow it to warm up to room temperature. Once the temperature has stabilized, check the liquid level in the bottle to make sure that you have the correct amount of syrup. You may need to pour more syrup into the bottle if the bottle is leaking.
Once the bottle is filled to the proper level, turn on the pump and empty the contents into a large container. Turn the pump back on and check the temperature. Once the bottle has reached the proper temperature, you can place it back inside the dispenser and turn it on. The pump should start up and run without difficulty. Once it is running smoothly, shut off the motor and wait a few minutes to see if the bottle returns to its original temperature.
After about five minutes, you should carefully open the top of the bottle. Look for leaks or cracks in the glass. If you find these problems, clean them with a solvent such as rubbing alcohol. If the problem is not fixed, replace the bottle and turn the power on. Use the syringe to clean out all the pieces inside the syrup container.
If your dispenser appears to be plugged, remove a few screws and carefully inspect the moving parts. A dripping syringe may be the culprit, so run a solvent through it and check for leaks. If none is found, the hose may be clogged with hair or dust and needs to be replaced. In most cases, this can be done without needing to disassemble the dispenser itself.
If none of these problems are the ones causing your pump to malfunction, then the motor is probably shot. To fix it, you need to use the correct part, such as a sleeve that fits over the pump. This allows you to fill the bottle again, reseal it and plug the unit back in. If you're using an older bottle style, then you'll need to use the syringe with a long thread rather than the shorter version that come with modern models. This ensures that the syrup stays smooth as well as being easy to pour into the bottle.
