Watch as we walk through the full process, from initial setup to real-world testing of hydraulic pump assemblies for heavy machinery. In this demonstration, we'll show you how liquid slugging during compressor startup can damage equipment and reveal practical solutions to prevent this common issue. You'll see actual pump assemblies from models like PC200-5, PC650, and WA900-3 in action, learn identification techniques for different pump types, and discover maintenance best practices to extend equipment lifespan and improve operational safety.
