Tier 4


National emissions standards call for the reduction of the six common “criteria pollutants” – particulate matter (PM), ozone, sulfur dioxide, nitrogen oxides (NOx), carbon monoxide and lead. Implementation of the standards has occurred in stages, or “tiers.” Diesel engines in every industry, in every application, from massive marine engines to small landscape equipment engines, are subject to the Environmental Protection Agency’s (EPA) emission reduction standards. Whether you work in construction, mining, water and wastewater or industrial plants, the emission reduction technologies on Final Tier 4 (FT4) diesel engines for portable pumps work to create more efficient diesel fuel combustion and manage PM, NOx and other pollutants, while still delivering smooth, reliable power.

Some of the advances in Interim Tier 4 (IT4) and Final Tier 4 (FT4) engines for Godwin portable pumps include:

  • Enhanced engine control technology
  • Diesel particulate filters
  • Field Smart Technology (FST)
  • PrimeGuard

These technologies ensure that Godwin pumps, by Xylem, fully comply with the EPA’s reduced emissions requirements.
