Could someone please provide a link to a video on how to operate a
Waters 501 HPLC pump (or a operator manual)?

Thank you.

Best advice is to contact Waters tech support.

Gerhard Kratz: thank you for your information but I was wondering if there was a manual for this pump online..

I have found manuals for 510 and 515 online but it is becoming difficult to find one for 501 model.

Thank you.

As I recall (memory is starting to fade) the 501 operation was close to the 401 pump. So look for the 401 manual too!

Operation of 501 and 510 pumps are nearly the same , they only differ by design.
501 is a serial piston type , 510 is parallel piston.
Flow control by a thumbwheel switch on both , and there is a upper pressure control knob , thats all.
If you use a control box for frequency control , the output terminals are also identical.
