Speedaire 2Z603C pump has a loud knock

Pump has a loud knock and will not build up enough pressure to close pressure switch. I

can take pump apart but I am afraid that because of the sound of the pump, that if probably is a rod bearing. I looked on some sites and the only parts I could find were gasket kits and valves. What would be a good replacement pump?
Thanks

Finding bearings shouldn't be a problem so long as you can read the numbers on it...

But where did you even find valves?
