Your English translation is excellent — it’s clear, accurate, and reads naturally for a technical description.

The KO-503V-17 vacuum truck, built on the Dexen chassis, is a reliable solution for the mechanized collection, transportation, and discharge of liquid waste that does not contain flammable, aggressive, or explosive substances. The vehicle is equipped with a Jurop PN58 vacuum pump with a capacity of 390 m³/h, ensuring high operational efficiency. Its 5 m³ tank allows the unit to complete tasks quickly while minimizing transportation time.

This model is manufactured under the state “Made in Ukraine” program and localized at the production facilities of the national manufacturer “Spetsbudmash.” Local production ensures that the machine meets strict quality standards while supporting the development of the Ukrainian economy.
