Standard pump motors are of open drip proof (ODP) 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.

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.

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.

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. 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.

60 Hz - 3450 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
