The Waukesha needs you.
While we at Enotools and Carlsen do not pretend to be willing to establish the SOP's for sanitizing your facility, I want to remind you of something:
The Waukesha might want a fresh set of o-rings right now.
Not a "lobe pump", the positive displacement, "winged rotor" design of your Waukesha pump is such that the small, low cost ($28 +/-) o- rings in your pump head take about 20-40 minutes to replace with a thorough cleaning of the parts inside the head.
Why now? With all of the solids you have potentially pumped through the last few months, it will give you peace of mind that your sanitizing rinse and intelligent storage before and after use is effective. And your o- ring seals are a consumable. They will wear out. And the pump will develop a drip.
A few drips an hour from a pump capable of 80 PSI at 1RPM while introducing the least amount of dissolved oxygen and keeping solids or turbidity increases to a bare minimum is not the end of the world. But it is annoying. And it's the only way this pump has to tell you that it's time.
My advice is to set it up as an annual chore to be done as part of the care and feeding of the best pump on the planet.
