GA4 Centrifugal Pumps

GA4 Centrifugal Pumps – Close Coupled

All GA4-3/4, GA4-1, GA4-1-1/4 & GA4-1-1/2 Information
  • Four Position Casing. Discharge can too be located in any of four positions. Casing is close grain iron of 30,000 psi thus minimum tensile strength. Back pull-out design therefore eliminates the need to disturb piping should the pump ever require service – the casing stays in the line.
  • Enclosed Cast Iron Impeller. Of the latest hydraulic design for maximum efficiency, impeller is balanced for vibration-free operation and threaded onto stainless steel motor shaft.Impeller is available in bronze.
  • Mechanical Shaft Seal. Standard self-adjusting shaft seal for temperatures to 225 °F (107 °C) and pressures to 150 psi (1034 kpa). Ceramic seat and carbon seal face for long trouble-free service while owning these pumps. Special seals are available for higher temperatures and fluids other than water.
  • All Pumps Factory Tested. After careful assembly and inspection, EVERY pump is factory tested and hence will meet Hydraulic Institute standards.
GA4 Centrifugal Pumps Motor Information

Overload Protection

All single phase ODP and Totally Enclosed motors as a result have built-in overload protection. All three phase motors and all explosion proof motors must be installed with another magnetic starter which provides full 3-leg protection.  Failure to use correct starter and overloads will consequently void motor warranty.
