- Confirmed DM220 Fitment — this membrane is specifically designated for the DM220 concrete core drill motor; verify against your parts diagram using part number 525538701.
- Restored Pressure Regulation — a correctly functioning membrane maintains consistent internal pressure or fluid separation within the drill system, keeping the motor performing as designed under load.
- Genuine Husqvarna Part — as an authentic OEM component, this membrane meets the same quality standards as the original, giving you confidence that the repair is done right the first time.
A membrane in a core drill motor system serves as a flexible diaphragm that regulates pressure, separates fluid chambers, or controls flow within the internal assembly — depending on its specific location within the unit. When this component becomes cracked, hardened, or distorted through wear or chemical exposure, pressure balance is disrupted, which can cause erratic motor behavior, fluid leaks, or loss of drilling performance. Replacing a worn membrane restores the correct operating conditions inside the drill motor, protecting surrounding components and maintaining consistent output during demanding core drilling work.
