Features of GM series

Both high viscosity and low viscosity liquids can be handled
When a low-viscosity liquid is handled by a conventional gear pump, “galling” and “seizing” tend to occur. SiC ceramic gears do not have these problems 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.
Magnetic drive type
Superior anticorrosive materials such as silicon carbide, silicon nitride, alumina ceramic, PTFE, carbon and stainless steel are used in liquid ends so that all sorts of chemical liquids can be handled. The GM type is ideal for handling chemical liquids which need strict control on liquid leakage and air contact.
Quiet liquid transfer with less pulsation
Without the pulsation that is common to reciprocating pump and gear pumps for general uses, liquid is transferred quietly and smoothly , not agitating or generating foam/bubbles.
High self-priming ability
Because the suction port is at the top of the pump, the pump chamber remains full when pump stops working. The self-priming capacity 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.
