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 fl ange, one piece threaded stainless steel shaft and ball/ball bearing construction.

Centerline discharge can be located in any of four positions. Back pull-out design eliminates the need to disturb piping should the pump ever require service - the casing stays in the line.

Of the latest hydraulic design for maximum efficiency, impeller is balanced for vibration-free operation and threaded onto stainless steel motor shaft.

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 troublefree service. Special seals are available for higher temperatures and fl uids other than water.

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