The Leak Detection Unit VSP 1TS is a powerful vacuum pump unit from MR Chemie, designed for bubble testing of weld seams, container bottoms, tanks and other metal structures where access is only possible from one side. The unit is part of the VSP series and is suitable for field and workshop use thanks to its robust construction and good suction capacity.

Key features and benefits

• Suction power at 100 kPa approx. 8 m³/h – provides rapid evacuation of connected vacuum box.

• Adjustable end discharge to approximately 15 kPa (negative pressure approximately –85 kPa) – provides high control over test pressure.

• Mains voltage 230 V / 50 Hz with power consumption 0.37 kW – suitable for industrial use.

• Dimensions approx. 440 × 200 × 400 mm and weight approx. 19 kg – manageable size for mobile use.

• Designed for use with MR Chemie vacuum boxes and testers where access is restricted – a safe method for leak testing and weld inspection.

Technical specifications

• Suction power: ≈ 8 m³/h at 100 kPa.

• Adjustable end vacuum: up to ≈ 15 kPa (≈ –85 kPa).

• Voltage: 230 V / 50 Hz.

• Power consumption: 0.37 kW.

• Dimensions: approximately 440 × 200 × 400 mm.

• Weight: approximately 19 kg.

Areas of application

• Inspection and leak testing of pipes, tanks and welds where only one side is accessible.

• Field use for maintenance and quality assurance in industry (oil & gas, chemical, ships, tanks).

• Combined use with vacuum boxes (90°, 270°, butt seam, etc.) for visual leak detection ("bubble test") with foam/indicator spray.

• Situations where compression testing is difficult or impractical, and where visual vacuum testing provides better results.
