IMO GA Series Herringbone Gear Pump
Superior Engineering and Low Cost of Ownership
GA Series gear pumps have long been workhorses in highly viscous applications within a multitude of industries due to their dependability, efficiency and low total life cycle costs. Engineered to reliably pump viscous fluids over a broad range of flows and pressures, the GA Series' superior between bearings, external gear design offers the benefits of pulse-free operation, dry-run capability and ease of maintenance.
- Variety of mounting arrangements
- Horizontal and vertical suction discharge openings
- Stuffing box accommodates packing or mechanical seals
- Minimal shaft deflection
- Reduced bearing loads and shaft deflection
- Accurate alignment with two-piece doweled construction
- Reduced wear rates
- Prolonged service life
- Efficient operation over a broad range of speeds, pressures and viscosities
- No speed reducers
- Only one coupling guard
Multiple Mounting Configurations
The cast iron GA Series pumps are available in three mounting configurations foot-mounted, flanged and close-coupled. With its multiple options and modular design, GA Series pumps can be customized to satisfy a wide range of applications.
- GAS: Foot-mounted
