The Multiquip 0806113630 Mechanical Seal HK9A-LN Dia. 30 is a genuine OEM mechanical seal designed for QP402H and QP402B centrifugal pumps. As a direct OEM replacement, this seal is manufactured to the exact material grade and dimensional tolerances required by Multiquip, ensuring a proper fit within the pump housing without rework or adaptation. Sourced directly through authorized Multiquip supply channels, part 0806113630 delivers the sealing integrity these pumps depend on during continuous dewatering and fluid transfer operations.
Key Features
- Precision-Grade Seal Material — Manufactured to OEM-specified face material and compression characteristics, maintaining the fluid boundary under the rotational loads typical of centrifugal pump operation.
- Direct-Fit Installation — Sized to the correct 30mm diameter interface, this seal installs directly into the pump shaft bore without shimming or modification.
- Confirmed Fitment — Verified for use on QP402H and QP402B centrifugal pumps, so you can order with confidence that 0806113630 is the right seal for your machine.
- Leak-Free Pump Performance — A correctly seated mechanical seal keeps process fluid contained within the volute, allowing the impeller to maintain full suction and discharge pressure across the operating range.
- Genuine OEM Part — Supplied under the Multiquip OEM parts program, meaning this seal meets the same specification as the component installed at the factory.
A mechanical seal sits at the point where the rotating pump shaft exits the pump casing, preventing fluid from escaping along the shaft during operation. It works by pressing two precision-lapped faces — one rotating with the shaft, one stationary in the housing — against each other to form a near-zero-leakage barrier. When the seal faces wear, chip, or lose their spring tension, the pump begins leaking at the shaft, which can lead to bearing contamination, reduced suction performance, and eventual pump failure if the seal is not replaced promptly.
