G Series Gear Pump

Internal gear pumps incorporating fine ceramic
gears

Both high viscosity and low viscosity liquids
can be handled
When a low-viscosity liquid is handled by a conventional gear pump,
“jamming” and “seizing” tend to occur. SiC ceramic gears do
not have this problem even when the pump functions at a high speed. Silicon
nitride ceramic gears show stable performance in handling high viscous liquids,
due to their strength and toughness.

Ability to handle fine
slurries
Now that gears and other sliding components including bearings are made of
ceramic, the handling of fine slurries hard and soft will not impair the
longevity of these pumps. Performance has been noticeably improved. Ceramic
gears make it possible to reduce spaces between parts, therefore out performing
conventional metal gear models.

Quiet liquid transfer with
less pulsation
Without the pulsation that is common to reciprocating pump and general use type
gear pumps, liquid is transferred quietly and smoothly no agitating or foaming.

High self-priming ability
Because the suction port is at the top of the pump, the pump chamber remains
full when pump stops working. Self-priming is enhanced at re-start.

Constant flow injection
Regardless of the temperature change, viscous liquid can be handled at accurate
flow rate, which cannot do with other pumps. As the output is linearly related
to rpm, the flow rate is easily controlled by changing speed.
