Pump Shaft
A worn or bent shaft is often the real reason a seal keeps failing repeatedly, even after replacement — runout beyond tolerance flexes the seal faces open on every rotation. Mech Seal Engineering manufactures pump shafts to exact OEM dimensions for KSB, Microfinish, and Flowserve pump ranges, machined and ground to the original tolerance for shaft diameter, keyway, and thread specifications. For pumps outside these brands, we manufacture shafts to drawing — send us your dimensional drawing or the worn shaft for reference, and we’ll produce a matching replacement in the appropriate steel or alloy grade for your service conditions.
Pump Shaft — KSB Pump
Precision-machined pump shafts manufactured to exact KSB pump drawings and dimensional tolerances, ensuring correct fit, balance, and alignment with existing pump components. Manufactured in corrosion-resistant stainless steel and duplex grades to match original material specifications, these shafts are built for direct replacement without requiring modification to bearings, couplings, or seal chambers. We manufacture to your specific KSB model and shaft drawing for accurate, reliable fitment.
Pump Shaft — Microfinish Pump
Precision-machined, drawing-matched, direct replacement fitment.
- Manufactured in stainless steel and duplex grades
- No modification needed to bearings or couplings
- Built to exact Microfinish pump dimensions and tolerances
Pump Shaft — Flowserve Pump
Precision-machined pump shafts manufactured to exact Flowserve pump drawings and dimensional tolerances, ensuring correct fit, balance, and alignment with existing pump components. Manufactured in corrosion-resistant stainless steel and duplex grades to match original material specifications, these shafts are built for direct replacement without requiring modification to bearings, couplings, or seal chambers. We manufacture to your specific Flowserve model and shaft drawing for accurate, reliable fitment.

Pump Shaft Sleeves
The sleeve’s entire job is to take the wear so the shaft itself doesn’t have to — it sits between the shaft and the seal or packing, and it’s designed to be the sacrificial, replaceable part. Which material makes sense depends on what’s wearing it down: Mech Seal Engineering manufactures sleeves in Stainless Steel for standard […]
