The Husqvarna 582590501 Radial Seal is a genuine OEM component designed for the DM280, DM340, and DMS280 concrete core drills. This seal is manufactured to Husqvarna's exact material and dimensional specifications, ensuring a proper compression fit within the drill motor assembly. Sourced directly from Husqvarna, it delivers the precise sealing performance these machines require. DHS Equipment supplies this part to help keep your core drilling equipment running at full capacity.
Key Features
- OEM-Grade Seal Material — Made to Husqvarna's exact elastomer and compression specifications, ensuring the radial sealing surface performs as intended under the operating pressures of a concrete core drill motor.
- Direct Drop-In Replacement — Engineered to match the original seating geometry of the DM280, DM340, and DMS280 drill motor housings, allowing straightforward installation without modification.
- Confirmed Fitment — Verified for use on DM280 and DM340 drill motors and the DMS280 drill motor system, covering both standalone motor and integrated system configurations.
- Leak-Free Motor Operation — A correctly seated radial seal prevents fluid or air bypass past the rotating shaft, maintaining consistent torque delivery and protecting internal motor components from contamination.
- Protects Internal Components — A worn or compromised radial seal allows contaminants — including water and concrete slurry — to migrate into the motor, accelerating wear on bearings and internal surfaces.
A radial seal forms a dynamic barrier around a rotating shaft, preventing fluid leakage and blocking external contaminants from entering the motor housing. In a concrete core drill like the DM280, DM340, or DMS280, the seal must maintain its integrity under continuous rotation and exposure to water and slurry used during wet drilling. When a radial seal wears or fails, fluid can bypass the seating surface, leading to loss of motor efficiency, internal corrosion, and potential damage to bearings and other precision components. Replacing the seal at the first sign of leakage restores the motor's operating integrity and protects the surrounding assembly.
