The YANMAR YDP20TN-Y1 is a rugged, portable trash (waste/debris-laden) water pump designed for demanding dewatering applications. Powered by a reliable, air-cooled YANMAR L-series diesel engine, this pump offers efficient performance, durability, and a long service life in challenging environments such as construction sites, mines, agricultural fields, or flood-prone areas.

Its compact footprint and self-priming design make it easy to transport, set up, and operate. Thanks to its 2″ suction and discharge port, it’s ideal for moderate flow trash-water pumping where debris may be present. The YDP20TN is built to withstand harsh conditions while delivering strong, consistent water throughput.

Key Features

• Rugged Construction
  Use of cast iron and cast steel parts for pump casing and impeller ensures durability in harsh environments.

• Portability
  Compact frame and relatively low weight (~57 kg) make it easy to transport; optional wheel kit available for easier movement across job sites.

• Large Fuel Tank
  13-liter fuel tank gives longer continuous run times between refuels.

• Low Vibration and Noise
  The 4-stroke diesel engine design helps minimize vibration and noise, improving user comfort during operation.

⚠️ Use Cases / Applications
