Pump shaft sleeves
Drawing-based pump shaft sleeves for mechanical seal, packing, spacer and wear-sleeve applications, with fit, runout and surface-finish requirements reviewed from customer drawings or samples.
Pump shaft sleeves protect shaft sealing or packing areas and provide replaceable wear surfaces. Dimensions, fits, bore quality, runout and surface-finish requirements are reviewed from the drawing or sample before quotation.
Yes. A sample can be reviewed together with photos, material information and any known fit or surface-finish requirements. A drawing is still preferred when tolerances, runout or coating thickness are critical.
No. RF Machining focuses on custom pump shaft sleeves made according to customer drawings or samples rather than universal standard sleeves.
In-house machining is separated from partner processes. Hard chrome plating, nitriding, QPQ, heat treatment and coating requirements can be arranged through long-term partners when specified.
