Vertical centrifugal pump or something else? 4

[myPAQ]

Hi, I need help determining what type of pump I should use for a machine I am designing. The machine is designed to dispense viscous liquids, such as shampoo, from about 1' off the ground to 5' off the ground. I will attach a picture of the current design to help explain. I've been doing research into vertical centrifugal pumps however I am not an expert in this area. I was hoping to gain any knowledge on what the best pump set up would be or potentially some resources I could look into.

The goal is to have the liquids be pumped from the bottom cartridges up into the dispensing nozzles.

Thanks in advance!

There are pumps designed for viscus liquids, though a slow speed centrifugal would likely work.
But what flow level are you talking about?
A peristaltic might make more sense.

Viking gear pumps are used throughout the soap manufacturing process. They are used in moving the raw ingredients such as oils and fats from the railcars to the plant. Viking pumps are used in both the saponification and sulfonation processes to move liquids like fatty acids, sulfonic acid and glycerine. They are also used in the blending and final packaging of the finished product. Viking pumps are able to handle a wide range of viscosities, have no pulsation, and flow rate can be adjusted easily with a variable frequency drive.

What flowrate?

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

Fluid dispensor pumps are usually some sort of PD ppump, wherther gear or screw.

This is a well worn path so search a bit more on fluid dispensing packages / visous fluid insertion pumps and similar.

Compnaies like this ( possibly too big but get you the right idea)

Drum pumps might be more applicable here

This looks ideal

I agree with the comments above, however, important information is missing ...

Your selection of pump will depend on:

1) Do you need one pump per container ?

2) What is the required flowrate ?

3) Do you have electic power and/or compressed air available ?

As mentioned by LittleInch, if the flow rate is modest, I agree that either a drum pump or tiny air operated diaphragm pump might be a good solution. Small AOD pumps are cheap, but of course require compressed air.

Also, why not put the dispensing cartridges ABOVE the dispensing nozzle ?.... This will facilitate pumped discharge by keeping the pump suction under liquid pressure

Hi Everyone,

Thanks for all the detailed replies! Sorry for my lack of details, truthfully I'm not an engineer so doing my best to learn as I go.

I am aiming for a flow rate of 2 GPM. I believe I will need a pump per cartridge.

I will look into compressed air and hope to get back to you in the next day or so.

The reason for not putting the cartridges above the nozzles is that I worry there is not enough room to house the cartridges and it would result in the nozzles being too low to the ground.

Cheers,
Jared

Soda dispensing machine use double diaphragm pumps and CO2. They are self priming and will stop automatically when the dispense valve is closed.
Some use peristaltic tube pumps.

Here is your self priming Air operated pump:
