Pump Shaft Sleeve

Pump Shaft Sleeve

IS SPECI. NO.
ASTM A532 GRADE 3A

shaft sleeve is a cylindrical hollow metal tube placed over the shaft to protect as it passes through the packing. Pump shafts are often protected from erosion, corrosion, and wear at leakage joints, seal chambers, internal bearings and in the waterways by renewable sleeves. The most common shaft sleeve function is that of protecting the shaft from packing wear at the stuffing box. A shaft sleeve used between two multistage pump impellers in conjunction with the inter-stage bushing to form an inter-stage leakage joint is called an inter-stage or distance sleeve.
