No verified differences are recorded for these comparison fields. Confirm the full nameplate and suffixes before choosing a replacement.
Check the fluid, concentration, temperature and solids against the fluid section, diaphragm and ball/check-valve materials. Matching port size alone does not establish chemical compatibility.
Confirm the thread or flange standard, required flow at discharge pressure, air supply and suction conditions. Maximum catalog flow is not the delivered flow at every operating point.
