Multiquip 12548 Spray Pump Shurflo 100-000-21

The Multiquip 12548 Spray Pump Shurflo 100-000-21 is a genuine OEM spray pump designed for Whiteman and International ride-on power trowel series including STX55, HTX44, HHN, HTN, JWN, and STXD6i models. As a factory-original component, this pump delivers the correct flow rate and pressure output required by the on-board water spray system on these machines. Confirm your model code against the fitment list to ensure correct application before ordering.

Key Features

• Genuine OEM Construction: — Built to the same output pressure and flow specification as the original Shurflo 100-000-21 unit, ensuring the spray system performs as the trowel was engineered to operate.
• Direct Drop-In Replacement: — Matches the original mounting footprint, port sizing, and electrical connections of the factory pump, allowing straightforward swap-out without fabrication or adaptation.
• Broad Ride-On Trowel Fitment: — Compatible with a wide range of Whiteman and International ride-on power trowels including STX55, HTX44, HHN34TVD, HTN series, JWN24, HTXG6DF, and STXD6i among others.
• Consistent Water Distribution: — Maintains steady spray coverage across the concrete surface, helping operators control curing conditions and surface finish quality during finishing passes.
• OEM Part Number Accuracy: — Sourced as Multiquip part 12548, cross-referencing Shurflo component 100-000-21, so you can order with confidence that you are receiving the correct unit for your machine.

The spray pump on a ride-on power trowel circulates water from the onboard tank to the spray nozzles positioned over the concrete deck. Keeping the surface adequately moistened during finishing prevents the concrete from setting too quickly and allows the trowel blades to work the surface evenly. When the spray pump fails or loses pressure, water flow to the nozzles drops off, which can result in uneven surface hydration, premature concrete hardening, and a compromised finish. Replacing a worn or failed pump promptly with the correct OEM unit restores full spray system function and keeps finishing operations running on schedule.
