As the high-quality, reliable alternatives to competitive models, G Series positive displacement gear pumps have the durability, flexibility and efficiency you need to safely and securely handle all your challenging fluid-handling applications.
Interchangeable with up to 95% of the mechanically sealed, packed and seal-less internal gear pumps in use today, with no need for piping, driver, baseplate or coupling modifications.
G Series pumps are designed to be part-for-part replacements for many competitor pump models and are available in cast iron, carbon steel and stainless steel.
An oversized bracket and seal chamber allows the use of numerous sealing technologies, including packing, mechanical seals and lip seals. The large cast-iron bearing housing allows the mechanical seals to be removed without the need to take the pump out of service.
