Multiquip 25807-502 Pump Assembly

The Multiquip 25807-502 Pump Assembly is a genuine OEM component designed for the MP1H, MP115E, MP120E, and MP1455HP masonry saws. As a direct factory replacement, this assembly restores the water delivery system that keeps the blade cool and controls dust during cutting operations. Sourced directly from Multiquip, the 25807-502 ensures exact compatibility with the MP-series masonry saw lineup sold and serviced across North America.

Key Features

• Genuine OEM Construction: — Manufactured to Multiquip's original design tolerances, ensuring the correct flow rate and pressure output for MP-series masonry saws.
• Drop-In Replacement: — Engineered to match the original mounting points and inlet/outlet connections on the MP1H, MP115E, MP120E, and MP1455HP, so installation is straightforward.
• Confirmed MP-Series Fitment: — Verified for use on MP1H, MP115E, MP120E, and MP1455HP masonry saws — always confirm your model before ordering.
• Consistent Water Flow: — Maintains steady coolant delivery to the blade, preventing overheating and extending blade life during heavy masonry cutting cycles.
• Dust Suppression Performance: — A properly functioning pump keeps water flowing to the cutting zone, helping operators meet dust control requirements on the job.

The pump assembly on a masonry saw circulates water to the blade during cutting, serving two critical functions: cooling the blade to prevent heat damage and suppressing silica dust generated by cutting brick, block, and stone. Without a working pump, blade life drops sharply and dry-cutting conditions create both a health hazard and a risk of blade warping. When the pump fails or loses prime, water flow becomes intermittent or stops entirely — making prompt replacement essential to keeping the saw operating safely and effectively.
