Cartridge Bearing assembly and shaft
The shaft is designed with a short overhand to Reduce shaft deflection Minimize vibration
Provided with hardened shaft sleeve to protect the shaft
Optional dimentionally interchangable heavy duty bearing cartridge assemblies.
Cartridge assembly is retained on a one piece frame
INPRO labyrinth seals standard for best-in-class bearing protection
Liners and Impellers for hard metal (WX) and elastomer lined (WXR)pumps have common dimensions and are interchangeable within the same pump size.
Frame supports the bearing cartridge which includes grease lubricated standard single row taper roller or Heavy Duty two row taper roller and parallet roller cylindrical bearings.Bearings are located on a large diameter shaft designed to minimize overhang and deflection.
Standard gland seal (packed box with lantern ring) requires flush water.
Where suction conditions allow, Atlas’s expeller seal can eliminate the need to supply water to the stuffing box. Where high suction pressures or series pumping is desired other methods of sealing must be utilized.
Expeller and expeller ring are constructed from Hi-Chrome material.
Shaft sleeve material is 420 SS hardened to 550 Brinell to protect the shaft from wear.
