SERIES 125 AND 4125, AK AND AL MODELS
It is the unique and unusually simple construction that has made our rotary pumps so adaptable to so many diversified installations. The possess excellent vacuum developing characteristics and operate equally well in either direction. Because of the cushioned action in providing a continuous and steady stream of liquid without foaming or churning, it is adaptable to an unlimited number of industrial applications.
The rugged construction of these heavy-duty pumps assures long life and peak, trouble-free operation on normal-duty installation and outstanding performance when handling liquids at greater pressures.
These heavy-duty pumps are furnished as standard with packed-type or mechanical seal construction for shaft protection and prevention of leakage. Packed pumps provide extra-deep stuffing box. The rotary-type mechanical seal works with, rather than against, pressure. It is selfadjusting and seals without leakage. Because of its method of sealing it prevents scoring of the pump drive shaft.
These heavy-duty pumps with mechanical seal can handle liquids with viscosities up to 15,000 SSU.

① For mechanical seal pumas on applications with viscosities above 15,000 SSU (3,300 cSt), provide details for recommendation.
② Standard seal can be used from –20°F to +225°F. With special construction, temperatures from –60°F to +650°F can be handled with this series pumps.
③ Nominal rating based on handling thin liquids.
④ For maximum recommended discharge pressures when handling other viscosities and/or other speeds, see performance curves.
Performance curves also show preferred construction.
Note: This sizes are not available in steel-fitted construction. They are not available neither in bronze fitted construction.
