I am looking to buy a centrifugal monoblock pump for my laboratory. The suction and discharge sizes are mentioned as 12mm x 12mm. Does anybody know what does it mean? Does it mean 12mm OD, or does it mean 1/2" BSP?

    $\begingroup$ Hi Abhishek, welcome to engineering.SE! Can you add a link to the specific pump you are looking at? The specified dimensions can vary by manufacturer, and a link will help add context for those who aren't familiar with 'centrifugal monoblock pumps'. $\endgroup$ – Chris Mueller Mar 21 '15 at 16:01

Centrifugal pumps typically go by nominal pipe size for the inlet and outlet connections. The first number is typically the inlet, and the second is the outlet. Normally the outlet is smaller (which is why you'll see 10"x8" centrifugal pumps but never 8"x10"). This is partly due to mechanical efficiency and partly to get a justifiably higher pressure. However in small sizes such as this one, both connections are the same.
