Frequently Answers and Questions

What are the operating conditions for these pumps?
These pumps are suitable for operation down to 30 Torr absolute (approx. 29 inches Hg vacuum reference 30 inch barometer), when sealed with 60 Deg F. water.
What are the different sealing liquid arrangements?
There are three sealing liquid arrangements based upon the amount of sealing water recovered and recirculated: No Sealant Recovery, Partial Sealant Recovery, and Full Sealant Recovery.
What is cavitation and how do I fix it?
Cavitation is recognized as a metallic noise in the pump when the pressure is low and the air flow is slight. To fix it, slowly bleed air into the pump through the cavitation valve until the noise disappears.
