Chemical gear pumps GX series
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 can not do with other pumps. As the output is linearly related to rpm, the flow rate is easily controlled by changing speed.

General description :
GATHER Industrie’s magnetic drive gear pump is made from stainless steel, Hastelloy or titanium and may be used as dosing pump, process pump or for laboratory service. The hermetically sealed gear pumps convey and meter in a non-pulsating manner even non-lubricating liquids such as water, salt solutions, solvents, acids and caustic solutions. As low-maintenance process pumps they can be optimally integrated into existing systems; when used for metering or dosing service they enable highly precise and reproducible flow rates to be attained. Based on the magnetic coupling and making use of new materials GATHER Industrie constantly advances the pumps originally intended for laboratory service to optimum acid or caustic solution pumps used in pilot facilities (miniplant) and for process technological applications. It goes without saying that the pumps meet the requirements of the Pressure Vessel Code and are ATEX compliant for use in hazardous areas.
