VB-2000 Series Flagship Heavy-Duty Oil-Free Piston Vacuum Pump (VB-2000V / VB-2000H)

Q: How does the performance of VB-2000H differ from VB-2000V under deep vacuum conditions?

While VB-2000V prioritizes maximum open-airflow (208 L/min at -700 mmHg), VB-2000H is specifically tuned for deeper ultimate vacuum levels down to -740 mmHg (-98.6 kPa) while still maintaining a robust 155 L/min airflow, ensuring rapid pull-down under high vacuum resistance.

The GOFLEX VB-2000 Series represents the pinnacle performance of our oil-free piston vacuum line, engineered specifically for high-demand industrial automation, multi-station CNC vacuum holding, hospital central negative pressure, and large-scale thermoforming packaging. Powering through heavy workloads with a 0.60 kW motor, 3/8" NPT/G high-flow ports, and an 11.0 kg reinforced alloy block, it offers two ultimate performance configurations: VB-2000V (delivering up to 208 L/min displacement) and VB-2000H (achieving deep vacuum up to -740 mmHg / -98.6 kPa with 155 L/min flow). Delivering 100% oil-free, quiet 60 dB(A) continuous duty, each unit includes a thermal protector and complete installation kit.

Technical & Application FAQ

What makes the VB-2000 the flagship model of the VB dry piston pump series?

The VB-2000 is the highest capacity pump in the series, delivering an unmatched displacement of up to 208 L/min on the VB-2000V (110V/60Hz). It combines maximum pumping speed with heavy-duty 3/8-inch porting, making it ideal for multi-station industrial automation and large vacuum reservoirs.

How does the performance of VB-2000H differ from VB-2000V under deep vacuum conditions?

While VB-2000V prioritizes maximum open-airflow (208 L/min at -700 mmHg), VB-2000H is specifically tuned for deeper ultimate vacuum levels down to -740 mmHg (-98.6 kPa) while still maintaining a robust 155 L/min airflow, ensuring rapid pull-down under high vacuum resistance.

Why is the 3/8-inch port size essential for the VB-2000's high displacement performance?

Moving 208 liters of air per minute through smaller standard fittings creates severe airflow restriction and line friction. The enlarged 3/8-inch NPT/G porting minimizes pressure drops across connected manifolds and ensures maximum suction efficiency at the work surface.

What maintenance schedule is recommended for the VB-2000 in continuous multi-shift operations?

Thanks to 100% oil-free self-lubricating PTFE technology, no oil changes or fluid monitoring are required. Simply inspect and clean the intake air filter element every 500 operating hours. Piston cup seals typically deliver 6,000 to 8,000 hours of continuous service before routine overhaul.
