Standard pump motors have open drip proof construction and are rated with jet pump service factors for continuous duty operation. Motors are 56 frame size with NEMA standard mounting flange, one piece threaded stainless steel shaft and ball/ball bearing construction.

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.

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 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.

60 Hz - 3500 RPM - ODP
Single Phase:
1/3 thru 2 Hp. - 115/230 Volt
3 Hp. - 230 Volt only
Three Phase:
1/3 thru 3 Hp. - 208-230/460 Volt
50 Hz - 2900 RPM - ODP
Single Phase: 110/220 Volt
Three Phase: 380 Volt

All single phase ODP (Open Drip Proof) and TEFC (Totally Enclosed Fan Cooled) motors have built-in overload protection. All three phase motors and all explosion proof motors must be installed with a magnetic starter which provides full 3-leg protection. Failure to use correct starter and overloads will void motor warranty.

Enclosed bronze impeller is of latest hydraulic design for maximum efficiency. It is balanced for vibration free operation and threaded onto stainless steel motor shaft.

FOR TEMPERATURES TO 500°F (260°C). Series G5-1-1/4 & 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. To order, add suffix "MJ" to pump catalog number for temperatures below 400°F (204°C) and add suffix "MJK" to pump catalog number for temperatures over 400°F (204°C). Example: G5-1-1/4-MJ. See Section on High Temperature Pumps for more information.
