Mobile pressure test unit 4DSY series

The 4DSY electric hydrostatic test pump is a compact high-pressure unit engineered for hydrostatic testing of pipelines, pressure vessels and valves in oil, gas and water applications. Suitable for laboratory and field use, it features rapid liquid filling, fast initial pressure build-up and automatic high/low flow switching to maintain a stable output during tests.

Key features

• Compact industrial construction for easy transport and installation
• Stable output pressure with automatic flow adjustment
• Low energy consumption
• Automatic high/low flow switching to stabilize pressure after the initial rapid rise (automatic reduction beyond ~1.6 MPa)
• Rapid filling and fast initial pressurization to reduce test setup time

Applications

• Hydrostatic testing of oil, gas and water pipelines
• Pressure vessel, boiler, valve and fire‑fighting equipment testing
• Laboratory and on‑site field hydrostatic tests; suitable for aviation, defense and research projects
