G-Series canned

motor pump has been the workhorse of the North
American sealless pump industry for over 50 years.
G Series pumps feature automatic hydraulic thrust

of rotation indication and precision front and rear
bearings.

G-Series are capable of pumping fluids from -400ºF
to 1000ºF and working pressures up to 5000 psi.
As with all Teikoku products, no special tools,
foundations, leveling or alignment are required for
installation.
