How the WHWL42.15N Pump Works

• Utilizes a triplex plunger system driven by a balanced crankshaft to generate smooth,
  consistent high-volume flow at 11 GPM.
• Ceramic plungers minimize friction and heat, protecting seals and maintaining volumetric
  efficiency during long hot-water duty cycles.
• Bronze connecting rods provide superior wear resistance versus aluminum rods, making the
  pump ideal for continuous-duty and elevated-temperature applications.
• Stainless steel valves accurately control inlet and discharge flow, maintaining steady
  2200 PSI pressure even at high flow rates.
• The oil-lubricated crankcase keeps internal components cooled and protected, reducing
  wear and extending pump life under heavy loads.
• Oversized bearings support the crankshaft and rotating assembly, reducing vibration and ensuring smooth,
  quiet operation at 1450 RPM.

Benefits of the WHWL42.15N

• High Flow Capacity: 11 GPM output supports multi-lance or multi-gun wash systems where
  volume is critical.
• Hot Water Capability: Designed to handle elevated inlet temperatures for
  sanitizing, degreasing, and hygiene-critical cleaning.
• Durable Internal Components: Bronze rods, stainless valves, and ceramic plungers maximize
  service life under continuous use.
• Reduced Maintenance: Oil sight glass and vented dipstick simplify routine checks and help
  prevent lubrication-related failures.
• Continuous-Duty Ready: Slow-speed 1450-RPM operation lowers mechanical stress, heat, and
  vibration for longer life.
• Factory-Certified Quality: Each unit is tested for flow, pressure, and mechanical integrity
  before shipment.
• Long-Term Value: Supported by a 5-year commercial warranty and U.S.-based parts and
  service network.

Typical Applications

• Dairy farms: Hot-water sanitation for equipment, stalls, milking parlors, and processing areas.
• Food processing plants: Washdowns to meet USDA and health-code sanitation standards.
• Vehicle sanitation centers: High-volume cleaning for trucks, trailers, and heavy equipment.
• Truck wash bays: Supports multi-gun commercial wash operations requiring high flow.
• Municipal & industrial cleaning: Ideal for wastewater facilities, tank rinsing, and
  public works maintenance.
• Agricultural operations: Continuous washdown of livestock areas, barns, and crop
  equipment under hot-water conditions.

Why Choose the WHWL42.15N?

• Purpose-built for high-volume, hot-water wash systems where flow, durability, and
  reliability are non-negotiable.
• 11 GPM at 2200 PSI provides the throughput needed for large bays, multi-user systems, and
  intensive sanitation tasks.
• Bronze connecting rods and stainless valves deliver superior durability in environments
  that would quickly wear out lighter-duty pumps.
• Hot water–capable design makes it a cost-effective solution for industries where heat is
  essential to remove fats, oils, proteins, and heavy residues.
• Backed by a 5-year commercial warranty and U.S.-based technical support for long-term
  peace of mind.
• A dependable choice for operators who want a high-flow, hot-water pump that is engineered
  for continuous-duty cycles and long service life.
