Key Features
- OEM-Matched Flow Specification — manufactured to Husqvarna's original pump output ratings, ensuring consistent water delivery to the blade during wet cutting operations.
- Direct Drop-In Replacement — engineered to the same mounting interface and porting as the factory-installed unit, allowing straightforward installation without modification.
- Confirmed Fitment for MS510, MS510G, and MS610 — verified compatibility across all three tile and masonry saw variants in this family.
- Sustained Blade Cooling — a properly functioning pump maintains the continuous water flow that keeps diamond blades cool and prevents premature wear during heavy-duty masonry cutting.
- Protects Cutting System Integrity — adequate water supply to the blade suppresses slurry dust and reduces heat buildup, directly supporting safe, controlled cutting in tile and masonry applications.
The pump in a wet-cutting tile and masonry saw is responsible for circulating water from the reservoir to the blade guard, keeping the diamond blade cooled and lubricated throughout the cut. Without sufficient water flow, blade temperatures rise rapidly, accelerating segment wear and risking blade damage or loss of cutting control. A failed or weakened pump can also lead to excessive dust generation at the cut line, reducing visibility and creating airborne silica hazards. Replacing a worn pump with a genuine OEM unit like this one restores the designed water pressure and flow that the MS510, MS510G, and MS610 rely on for consistent, safe operation.
