2018 Honda Power Equipment WB20

Turning ponds into puddles.

Extensive selection for irrigation, flood control, light construction, pool draining, and more.


  • EASY STARTING HONDA OHV COMMERCIAL ENGINE: The durable Honda GX series commercial grade engine is easy starting and provides ample power for the toughest conditions.
  • DURABLE SILICON CARBIDE MECHANICAL SEAL: The WB20 features abrasion-resistant silicone-carbide seals for extended wear.
  • 4 VANE HIGH EFFICIENCY IMPELLER: The WB20's exclusive, Honda-designed 4 vane impeller offers improved performance and high efficiency.
  • CAST IRON VOLUTE: The rigid-mount cast iron volute reduces case wear, increasing the life of the pump.
  • HEAVY DUTY FULL FRAME PROTECTION: Protects the pump, while offering a convenient tie down location for transport.
  • ISOLATION MOUNTED ENGINE AND PUMP: High performance mounts minimize vibration, keeping the pump from “walking” away or “burying” itself in soft soil conditions. The reduced vibration also reduces wear on components, increasing the pump's durability.
  • PROTECTED BY HONDA OIL ALERT®: Protects the pump by shutting the engine off when low oil is detected.
  • LARGE STRAINER: The strainer allows up to 8 mm (5/16 in.) solids to pass through, helping to prevent clogging.
