Multiquip 515070825 QPT405SLT Key

The Multiquip 515070825 QPT405SLT Key is a genuine OEM replacement designed for the QPT405SLT centrifugal pump. Sourced directly from Multiquip, this key ensures an exact match to the original component, maintaining the precise tolerancing required for proper shaft-to-component engagement. If you're servicing a QPT405SLT and need a dependable replacement, this is the correct OEM part for the job.

Key Features

• Genuine OEM Shear and Drive Tolerance — Manufactured to the exact dimensional spec required for positive power transfer without slippage or misalignment in the QPT405SLT drivetrain.
• Direct Slot Fit — Drops into the existing keyway on the shaft and mating component with no material removal or reworking required.
• QPT405SLT Centrifugal Pump Fitment — Confirmed fitment for the Multiquip QPT405SLT, so you can order with confidence that this is the right part for your machine.
• Protects Shaft and Hub from Rotational Play — A correctly sized key locks the impeller or pulley to the shaft, preventing wear that can damage both the shaft and the driven component over time.
• OEM Sourced for Authentic Quality — As a genuine Multiquip part, this part meets the same material hardness and geometry standards as the component it replaces, unlike generic hardware-store equivalents.

A key is a small but critical component in any rotating drivetrain. It sits in a machined slot — called a keyway — cut into both the shaft and the hub of a mating part such as an impeller, pulley, or coupling. Its job is to lock those two components together rotationally so that torque is transferred cleanly from one to the other. When a key wears, shears, or goes missing, the driven component can spin freely on the shaft, causing complete loss of pump output and potential damage to the shaft and hub surfaces. Replacing it promptly with the correct OEM part restores full mechanical engagement and protects the surrounding components from further wear.
