The Multiquip 30540 Retardant Spray Pump is a genuine OEM component designed for STXDF, PRX, and HHNG5 series ride-on power trowels. Sourced directly from Multiquip, this pump delivers the exact performance and dimensional fit required by these machines. It is the correct factory-specified replacement for STXDF dual-fuel hydrostatic trowels, PRX hybrid power floats, and HHNG5 Whiteman ride-on trowels, ensuring seamless installation without any guesswork on compatibility.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design specifications, ensuring the pump delivers correct flow rate and pressure output for the retardant spray system on ride-on trowels.
- Direct-Fit Replacement — Engineered as a drop-in replacement that connects directly to the existing spray system plumbing on compatible machines, matching original port sizing and mounting configuration.
- Broad Ride-On Trowel Compatibility — Confirmed fitment across STXDF, PRX, and HHNG5 series machines, covering hydrostatic, hybrid, and heavy-duty Whiteman ride-on trowel platforms.
- Consistent Retardant Coverage — A properly functioning pump maintains even distribution of curing retardant across the slab surface, supporting uniform finish quality and preventing premature blade drag or surface tearing.
- Long-Term Pump Integrity — OEM materials resist wear from retardant chemistry, helping the pump maintain reliable output across extended finishing operations.
The retardant spray pump circulates surface retardant from the onboard tank and distributes it evenly beneath the trowel blades during finishing operations. This controlled application slows surface curing, allowing operators to work the concrete longer and achieve a consistent, high-quality finish. When the pump fails or loses output pressure, retardant coverage becomes uneven or stops entirely, which can cause the blades to drag, score the surface, or make the slab unworkable before finishing is complete.
