Simple Fluid Dispensing Question
Simple Fluid Dispensing Question
(OP)
I have a simple fluid dispensing question. My situation requires feeding a pump with isopropyl alcohol. I would like to place whatever container dispenses the fluid above the suction side of the pump. The pump is currently equipped with a 3/8 inch ID tube at the suction side. The dispenser should not be automated, it can simply be a container with a tube fitting.
My first thought was to go with a carboy equipped with a tube fitting or valve, then rigging up some kind of connection to the pump.
I thought you guys might be able to come up with something better. I'm new to automation and am not aware of most of the products out there.
The application is for a tooling fixture used in a manufacturing clean room, if that is of any help.

There are also mostly metal devices to do the same job; they may be required in some locations.
Your specification is so far not clear about what you intend to use for a pump, how it's powered, when it's on, how much or how fast it dispenses, etc.

What are the metal devices you referred to?
RE: Simple Fluid Dispensing Question
The pump you have specified is an air powered reciprocating piston pump with a high discharge pressure rating.
Since high pressure pumps like that typically use hard-seated check valves, I wouldn't put the supply reservoir above the pump suction. Hard-seated check valves don't always seal very well, and if they both stick open, the reservoir will empty through the pump whether the pump is on or off.
