How the Pump Works

Triplex hot-water design with stainless head and PTFE seals

• Utilizes a triplex plunger pump design to produce a constant flow of water at
  high pressure, ideal for hot-water cleaning systems.
• Ceramic plungers and stainless steel valves deliver high
  efficiency while reducing wear over long service intervals.
• The stainless steel head enhances thermal and chemical resistance, preventing
  premature failure where standard brass heads may struggle.
• PTFE high-temperature seals maintain sealing integrity under elevated
  temperatures and exposure to detergents and cleaning chemicals.
• The 24 mm solid keyed shaft provides a secure mechanical connection to compatible
  drive systems, simplifying integration into commercial hot-water rigs.

  at job sites and remote facilities.

Why Choose the RHW1515N

4.0 GPM, 2,200 PSI stainless hot-water pump

• Not all pumps are engineered for high-temperature cleaning; the
  RHW1515N stands out with its stainless steel head,
  PTFE high-temp seals, and hot-water rating up to 185°F.
• The slower 1,450 RPM operating speed reduces heat buildup and mechanical
  stress, supporting longer service life in continuous-duty applications.
• Balanced performance of 4.0 GPM and 2,200 PSI delivers the flow and pressure
  required for sanitation-focused industries without sacrificing reliability.
• Backed by a 5-year commercial warranty and U.S.-based service support, it
  provides confidence for operators who cannot afford downtime.
