  (verify chemical and temperature compatibility).
• Agriculture: Barns, livestock trailers, implements, and large wash pads for equipment sanitation.
• Facilities & infrastructure: Parking garages, stadiums, theme parks, transit hubs, and public spaces.
• Contractor wash rigs: Skid or trailer-mounted systems for high-throughput mobile cleaning operations.

Installation & Maintenance Best Practices

• Align & support: Use properly sized couplers or pulleys and rigid mounting to prevent shaft and
  bearing stress.
• Protect the inlet: Oversize filtration and keep suction lines short and unrestricted to avoid cavitation.
• Unloader & bypass: Size the unloader correctly and route bypass flow to a tank or cooled return line.
• Prime before starting: Ensure water is flowing through the system to prevent dry running and seal damage.
• Oil care: Monitor the sight glass regularly and service with non-detergent pump oil on a set schedule.
• Winterize: Flush detergents and run pump saver or antifreeze for cold-weather storage and freeze protection.

Summary

• The WHWL50.20NB industrial pressure washer pump delivers
  13.2 GPM at 3,000 PSI and 1,450 RPM with a
  24 mm solid shaft, making it a high-flow, continuous-duty solution for
  fleet washing, municipal service, industrial sanitation, food processing, and agricultural wash bays.
