VB-1800 Series Heavy-Duty Oil-Free Piston Vacuum Pump (VB-1800V / VB-1800H)

Q: Why does the VB-1800 use a 3/8-inch port size instead of the 1/4-inch found on smaller models?

With maximum displacement reaching 185 L/min on the VB-1800V, a 1/4-inch port would cause severe pneumatic throttling and friction loss. Upgrading to a 3/8-inch NPT/G port reduces line resistance by over 40%, ensuring unrestricted airflow and optimal vacuum pressure delivery.

Q: What is the primary difference in application suitability between VB-1800V and VB-1800H?

VB-1800V is optimized for rapid volume evacuation and high-flow automation (185 L/min at -700 mmHg), such as large CNC suction tables and multi-station packaging machines. VB-1800H targets high-resistance processes requiring deeper vacuum (-740 mmHg / -98.6 kPa) with a flow rate up to 135 L/min.

The GOFLEX VB-1800 Series Heavy-Duty Oil-Free Piston Vacuum Pump is built for large-scale industrial automation, heavy CNC vacuum holding, multi-station packaging systems, and central laboratory suction. Featuring an upgraded 3/8" NPT/G port diameter and an 11.0 kg reinforced alloy block, the series eliminates airflow throttling under high displacement. Choose VB-1800V for massive pumping speeds up to 185 L/min or VB-1800H for deep negative pressure up to -740 mmHg (-98.6 kPa). Delivering 100% dry, maintenance-free continuous S1 duty at a low 60 dB(A) noise level, it comes pre-equipped with an intake filter, muffler, and vibration isolation mounts.

Technical & Application FAQ

Why does the VB-1800 use a 3/8-inch port size instead of the 1/4-inch found on smaller models?

With maximum displacement reaching 185 L/min on the VB-1800V, a 1/4-inch port would cause severe pneumatic throttling and friction loss. Upgrading to a 3/8-inch NPT/G port reduces line resistance by over 40%, ensuring unrestricted airflow and optimal vacuum pressure delivery across larger piping networks.

How does the structural design of the VB-1800 (11.0 kg) accommodate higher thermal loads?

The VB-1800 features an expanded aluminum cooling housing with reinforced motor windings, increasing its total weight to 11.0 kg. The enlarged surface area enhances convective heat dissipation, stabilizing internal chamber temperatures during continuous 24/7 heavy industrial cycles.

What is the primary difference in application suitability between VB-1800V and VB-1800H?

VB-1800V is optimized for rapid volume evacuation and high-flow automation (185 L/min at -700 mmHg), such as large CNC suction tables and multi-station packaging machines. VB-1800H targets high-resistance processes requiring deeper vacuum (-740 mmHg / -98.6 kPa) with an airflow up to 135 L/min.

Can the VB-1800 be integrated into automated machinery with long pneumatic tubing runs?

Yes. Due to its high flow output (up to 185 L/min) and enlarged 3/8-inch manifold interface, the VB-1800 maintains stable vacuum pressure even across extended piping networks without suffering significant pressure drops.
