VRT3-310BPKG | 4500 PSI Unloader Kit Pump Package Assembly

VRT3-310BPKG | 4500 PSI Unloader Kit Pump Package Assembly

• The VRT3-310BPKG unloader kit is a heavy-duty, retail-ready VRT3 assembly
  engineered to regulate and protect systems in the 310 bar (≈4,500 PSI) class at
  flows up to 10.5 GPM.
• When the spray trigger is released, the valve immediately diverts flow to bypass,
  preventing dangerous overpressure and protecting pumps, hoses, guns, and accessories.
• Designed for daily use in contractor and industrial environments, this kit
  delivers smooth, repeatable pressure control in a clean, ready-to-install format that speeds
  service-counter sales and field replacements.

What This Means For Your Rig

• In high-pressure systems, the unloader is the backbone of safety and performance,
  keeping pressure under control as tools, tips, and hose lengths change.
• The VRT3-310BPKG helps stabilize working pressure across long hose runs, turbo
  nozzles, and demanding tools, reducing heat, chatter, and seal wear.
• The retail kit format organizes components for quick identification, helping
  technicians complete installs faster and with fewer callbacks so equipment gets back to work
  quickly.

Performance Specs (Quick Reference)

• Max Pressure: 310 bar (approximately 4,500 PSI)
• Max Flow: up to 10.5 GPM
• Temperature: up to 194°F (90°C) typical for VRT3 class (verify seal set for hot chemical use)
• Connections / Ports: Inlet, Outlet, Bypass – 3/8 in NPT female (National Pipe Thread, US)
• Control: adjustable high-pressure regulation with internal black-spring class
• Typical Use: trapped-pressure unloader for commercial cold- or hot-water washers

Build & Retail Kit Format

• Reinforced VRT3 body and precision valve stack are designed for continuous duty
  in harsh environments.
• Metal threaded ports support repeatable torque and leak-resistant sealing, even
  under high pressure and vibration.
• Standardized port locations simplify clean plumbing to gauges, hose reels, and
  return-to-tank lines.
• Retail-ready packaging keeps small parts organized, speeds counter transactions,
  and helps techs complete shop or field installs quickly and consistently.

Benefits & Differentiators

• High-pressure class: stable 4,500 PSI regulation for heavy-duty cleaning power.
• Smooth bypass behavior: reduces pressure spikes, water hammer, and heat during
  trigger cycling.
• Faster service: organized kit format shortens installation time and minimizes
  downtime.
• Predictable maintenance: shared VRT3 wear parts and familiar repair practices
  across fleets.
• Flexible plumbing: standard 3/8 in NPT-F ports and multiple layout options
  support neat routing and repeatable builds.
• Proven platform: VRT3 family is widely adopted by OEMs, service centers, and
  professional contractors.

Industries & Applications

• Contractor-grade rigs and mobile wash fleets
• Industrial pressure washers and manufacturing plants
• Commercial facilities and maintenance crews
• Municipal and public works equipment washdown
• Construction and rental yards for heavy equipment cleaning
• Agriculture and food equipment washdown (with verified chemical compatibility)

Compatibility & Fit (Mounting, Plumbing, Nozzles)

• Plumbing & orientation: install downstream of the pump and upstream of the
  hose or reel; route bypass back to tank when your system requires recirculation.
• Use thread sealants approved for high-pressure water service and verify torque on
  metal fittings for leak-free operation.
• Porting standard: Inlet, Outlet, Bypass are 3/8 in NPT female. If adapting to
  other thread standards, use rated fittings and confirm sealing surfaces and flow path.
• Power pairing: ideal for triplex pumps delivering up to 10.5 GPM in the
  4,000–4,500 PSI range on gas-engine or electric builds.
• Include a thermal relief valve, inlet filtration, regulator and gauge, and
  burst-rated hose and wand assemblies for a complete system.
• Nozzle & orifice guidance:
  • Select a spray tip orifice that matches pump GPM at the target PSI; correct orifice is
    essential for stable pressure and unloader performance.
  • With water flowing (trigger open), adjust to reach working pressure, then secure the setting
    per your SOP.
  • Turbo nozzles can create momentary spikes; ensure every component—including the unloader—is
    rated at or above system pressure with margin.

Setup, Service & Reliability

• Prime with clean water, purge air, and confirm supply before first start to avoid cavitation or
  false readings.
• Adjust pressure only with the trigger pulled to prevent over-pressure and ensure
  accurate setup.
• Inspect inlet screens regularly and monitor for chatter or creeping pressure as
  early indicators of wear or contamination.
• Service on a preventive schedule using appropriate VRT3 wear parts to maintain
  stable performance and reduce unplanned downtime.
• Keep temperature, chemical exposure, and water quality within manufacturer limits to maximize seal
  life and overall efficiency.

What Is Included

• Use the 310 bar (approximately 4,500 PSI) rating in titles and bullet points for
  accuracy.
• Standardize your catalog to 3/8 in NPT female for all VRT3 inlet, outlet, and
  bypass ports and document any included adapters so installers can match threads on the first visit.
