RW15HT | 4 GPM 4000 PSI Hot Water Pump 185°F High Temp Use

Annovi Reverberi RW15HT High-Temperature Triplex Plunger Pump

The Annovi Reverberi RW15HT is a high-temperature, commercial-grade triplex plunger pump built for
demanding cleaning applications that require dependable performance with hot water. Rated at 4.0 GPM
and 4,000 PSI, it operates at 1,450 RPM and uses a 24mm solid shaft
for straightforward integration into belt-drive or direct-drive systems.

Designed as a direct replacement for the General Pump TSS1511, the RW15HT matches the same mounting
footprint and shaft configuration for a true drop-in swap on rebuilds, upgrades, and OEM builds. Unlike standard
cold-water pumps, the RW15HT supports inlet temperatures up to 185°F, helping hot-water systems
break down grease, oil, and heavy residues faster with less chemical dependence.
