Problem with different hydraulic connection sizes on all CNC machines!

Problem with different hydraulic connection sizes on all CNC machines!

Problem with different hydraulic connection sizes on all CNC machines!

Hello guys,

I am supplying a Venturi Vac to my clients which is installed directly on their CNC Machine Coolant Pumps (photo attached).

This is done by introducing a Tee connection on the discharge end of the pump as shown. The straight line of the tee is connected to the hydraulic coolant pipe, whereas the bypass port is where I install my Venturi. The venturi produces a vacuum with which I recover coolant from the waste bin(it passes through an inline filter).

Now the problem here is that most machines have a variety of connections. For example, some pumps have a 1" BSP where some have 3/4" BSP and some other thread standards as well. So this requires me to inspect each machine beforehand and then supply each set with the appropriate fittings for each machine.

Isn't there a way I could simplify this? Right now the Venturi is installed directly to the pump. I eventually intend to mount it onto the machine body using a magnetic plate. But I don't know how I can find a 'one-size-fits-all' type of a connection, if even there is one.

The motive in the venturi is the coolant from the pump, so I cannot use a vacuum pump or any such external drivers. Any help will be great. Thank you
