Discharge can be located in any of four positions. Casing is close grain iron of 30,000 psi minimum tensile strength. Back pull-out design eliminates the need to disturb piping should the pump ever require service - the casing stays in the line. Openings are provided for test gauges, for venting and for draining the pump.

Prevents wear on casing and is easy to replace.

Taking out only 4 cap screws allows removal of pumping assembly without disturbing piping.

Standard self-adjusting shaft seal for temperatures up to 225°F (107°C) and pressures to 150 psi (1034kpa). Ceramic seat and carbon seal face for long trouble-free service. Special seals are available for higher temperatures and fluids other than water.

After careful assembly and inspection, EVERY pump is factory tested and will meet Hydraulic Institute standards.

Enclosed Bronze Impeller is of the latest hydraulic design for maximum effi ciency. It is balanced for vibration-free operation and threaded onto stainless steel motor shaft.

Series GNA5-1-1/4 and and all G6-1-1/4 pumps are available in a Jacketed Seal Cavity design for pumping hot oil, hot water and heat transfer fluids in common use in high temperature heating or cooling applications. This feature greatly extends seal life in high temperature applications.
