|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.|
|Four Position Casing|
|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. It is precision fit to shaft with key drive and cap screw lock.|
|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 fluids other than water.|
|After careful assembly and inspection, EVERY pump is factory tested and will meet Hydraulic Institute standards.|
|60 Hz - 1750 RPM - ODP|
50 Hz - 1450 RPM - ODP
Single Phase: 115/230 V
Three Phase: 208-230/460 V
|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.|
