Chemical gear pumps GM series

Features of GM series

Magnetic Drive Type

The GM type is ideal for handling chemical liquids which need strict control on liquid leakage and air contact.

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.

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.

Specifications (50/60Hz)

*1 These are maximum values, which vary depending on motor speed and liquid viscosity.
*2 Motor speed and motor output suited to the viscosity of your liquid should be selected.
