If you are looking for a pump to dispense liquid from a bottle or barrel, you may need to know the thread size of the container neck.
Sometimes this will be written on the inside of the cap, or given in the specifications of the product.
However if the thread size is unknown is it simple to work out by measuring it yourself, as explained below.
Burkle offer an extensive range of liquid pumps to dispense liquids from containers, bottles and barrels in scientific, industrial, food production and other environments.
To make sure the pumps will fit all containers, they also offer a range of adapters so you can adapt any bottle to any pump.
In order to choose the right one(s) you first need to work out the thread size, as shown below;
