The Multiquip 12628 Spray Kit Pump is a genuine OEM component designed for STH series hydrostatic ride-on trowels. As an authorized Multiquip OEM part, 12628 is manufactured to the same specification as the original, ensuring a direct, compatible replacement for the spray system on your machine. Sourced from Multiquip's official parts program and sold by DHS Equipment, this pump is the correct choice when restoring full spray kit function to your STH trowel.
Key Features
- Genuine OEM Pump Construction — Built to the same pressure and flow specifications as the original spray kit pump, maintaining consistent output across the spray system.
- Direct Installation Fit — Connects to the existing spray kit mounting points and fluid lines on STH hydrostatic ride-on trowels without adaptation.
- STH Series Compatibility — Confirmed fitment for STH hydrostatic ride-on trowels, covering the full STH family of Multiquip finishing machines.
- Consistent Spray Delivery — A properly functioning spray pump ensures even, controlled distribution of release agent or water across the trowel deck, protecting both the concrete surface and the blades.
- Genuine Multiquip OEM Sourcing — Part 12628 is supplied directly through Multiquip's authorized parts channel, so you receive the correct component with full confidence in its origin.
The spray kit pump is responsible for drawing and pressurizing fluid — typically a form release agent or water — and delivering it through the spray system mounted on the ride-on trowel. This keeps the concrete surface from sticking to the trowel blades during finishing passes, which is critical for achieving a clean, consistent finish. When the pump fails or loses output pressure, spray coverage becomes uneven or stops entirely, leading to blade drag, surface defects, and increased wear on finishing components.
