Rotary Gear Pumps

Bronze Rotary Gear Pumps

Service life will be increased substantially if the liquid pumped is clean and has some degree of lubricity. These positive displacement pumps have tight tolerances.

Stainless Steel Rotary Gear Pumps

Positive displacement. Little flow decrease with pump pressure increase. Flow increases with speed increase.

Cast Iron Rotary Gear Pumps

Close tolerances require clean liquids. Viscous liquids require lower pump speeds. Positive displacement. Little flow decrease with pump pressure increase. Flow increases with speed increase.

Plastic Rotary Gear Pump

Close tolerances require clean liquids. Viscous liquids require pump speeds. Positive displacement. Little flow decrease with pump pressure increase. Flow increases with speed increase.
