Description
T20GA6-1-1/2 Burks Pump
T20GA6-1-1/2 Close Coupled Centrifugal Pump
GA6-1-1/2 General 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 Bronze Impeller. Another of the latest hydraulic design for maximum efficiency, impeller is balanced for vibration-free operation. Therefore it is precision fit to shaft with key drive and cap screw lock.
- 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.
- Bronze Shaft Sleeve. Gasketed and keyed hook-type sleeve protects shaft while in use from wear and corrosion in seal area.
- All Pumps Factory Tested. After careful assembly and inspection, EVERY pump is factory tested and hence will meet Hydraulic Institute standards.
- GA6 Series pumps are not available with 7-1/2 HP Totally Enclosed or Explosion Proof motors.
Motor Information
JM Type motors have NEMA standard mounting flange, extended steel shaft and dual bearings. These motors offer the advantages of quiet operation, controlled shaft deflection for longer seal life, and bearings sized to provide good service life. All motors are supplied by manufacturers with national field service facilities.

While Voltages may differ from some suppliers, please call us to confirm specifications.
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.
