Shaft Sleeve Information
Gasketed and keyed hook-type sleeve protects shaft from wear and corrosion in seal area.
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.
GA6 Series pumps are not available with 7-1/2 HP Totally Enclosed or Explosion Proof motors.
Four Position Casing
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.
Mechanical Shaft Seal Information
Standard self-adjusting shaft seal for temperatures 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 fl uids other than water.
After careful assembly and inspection, VERY pump is factory tested and will meet Hydraulic Institute standards.

All motors must be installed with magnetic starter which provides full overload protection on all legs. Failure to use correct starter and overloads will void motor warranty.
Enclosed Bronze Impeller
Of the latest hydraulic design for maximum efficiency, impeller is balanced for vibration-free operation. It is precision fit to shaft with key drive and cap screw lock.
