GAH Series
Product Type:
External Gear Pumps


The GAH Series melds the capabilities of the high-performance GA Series with high system pressure designs. The GAH Series pumps provide precise and pulseless flows from as low as 8.5 mL/min, and can withstand system pressures up to 5500 psi. Featuring Micropump suction-shoe design, GAH Series pumps self-compensate for wear, ensuring near zero slip and long pump life. Pumps are available in a wide range of materials and configurations.
