The Husqvarna 525401901 Electric Water Pump Kit FS4400 is a genuine OEM replacement designed for the FS4400 and FS4600 floor saws. Sourced directly from Husqvarna's construction equipment line, this kit delivers an exact match to the original assembly, ensuring the water delivery system operates as intended. DHS Equipment supplies this part to help keep your floor saw performing at full capacity on the job.
Key Features
- Genuine OEM Water Pump Specification — Manufactured to Husqvarna's exact flow rate and electrical requirements, so the pump circulates water at the correct pressure for effective blade cooling and dust suppression.
- Complete Kit Configuration — Supplied as a full electric water pump kit, including the components needed for a straightforward swap-out without sourcing individual pieces separately.
- Confirmed Fitment for FS4400 and FS4600 Floor Saws — Engineered specifically for the FS4400 and FS4600 floor saw platforms, cross-reference part number 525401901 against your parts diagram before ordering.
- Restores Blade Cooling and Slurry Control — A functioning water pump keeps the diamond blade cool and controls silica-laden slurry at the cut line; a failing pump accelerates blade wear and raises dust exposure on site.
- Dust and Silica Exposure Control — Proper water flow to the blade is a critical part of wet-cutting dust suppression, supporting compliance with silica dust control requirements on concrete cutting operations.
The electric water pump on an FS-series floor saw delivers a continuous flow of water to the cutting blade during wet-cutting operations. This water serves two purposes: it cools the diamond blade to prevent overheating and premature segment wear, and it suppresses the fine concrete and silica dust generated at the cut line. When the pump fails or loses flow, the blade runs dry — leading to rapid blade degradation, reduced cut quality, and elevated airborne dust levels that create a health hazard for operators. Replacing this assembly with the correct OEM kit restores full water delivery and returns the saw to safe, productive operation.
