Yamaha YP20G
RUGGED, RELIABLE AND THE MUSCLE TO GET THE JOB DONE
When you have water to move, you need reliable power to move it. Yamaha water pumps are rugged, reliable and have the muscle to get the job done. They deliver high-volume/low-pressure for rapid water transfer or de-watering. They also work great in various fire-fighting applications. And both pumps have a cast iron impeller and volute case — that means these pumps withstand wear from grit, sand, silt, etc. (but they are not designed for solids or highly viscous materials).
The YP20G is powered by a 4 hp, 123cc, OHV 4-stroke engine that's quieter, more powerful and consumes less fuel than comparable engines.
  • Pumps up to 160 gal/min (9,600 gal/hr) through a two inch port.
  • Delivers a 98 foot total head, with a 23 foot suction head.
  • Impeller and volute case are cast iron for greater strength and durability; and they withstand wear from grit, sand, silt, etc.
  • Durable carbon-ceramic seats are easy to replace and they reduce abrasion for long pump life.
  • Standard National Pipe Thread (NPT) fittings connect easily with the suction and discharge hoses.
  • Sturdy tubular frame for added protection.
  • Large muffler for quiet operation.
  • Hose and pick-up screen can be sourced locally.
  • Intake Hose: rigid type.
  • Discharge Hose: flexible type.
  • Pickup: small hole — 1/4 inch screen.
