VB-1400 Series Oil-Free Piston Vacuum Pump (VB-1400V / VB-1400H)

Q: What are the primary performance advantages of the VB-1400 compared to lower displacement models like the VB-1200?

The VB-1400 features a upgraded motor rated up to 0.67 kW (60Hz), delivering a maximum displacement of 145 L/min on the VB-1400V variant. This represents an ~16% increase in evacuation speed over the VB-1200V, making it far better suited for multi-station automation lines and larger vacuum vessel pump-down cycles.

Q: How does the motor power requirement vary between VB-1400V and VB-1400H under 110V vs 220V power grids?

Under 110V/60Hz, VB-1400V draws up to 0.67 kW (5.9 A) to achieve 145 L/min airflow, whereas VB-1400H draws 0.44 kW (3.9 A) for deep vacuum at 105 L/min. On 220V grids, power consumption ranges between 0.35 kW and 0.55 kW depending on model variant and frequency.

The GOFLEX VB-1400 Series High-Capacity Oil-Free Piston Vacuum Pump is an advanced dry vacuum solution designed for demanding OEM automated machinery, multi-channel lab manifolds, edge-banding equipment, and pharmaceutical packaging lines. Engineered with an upgraded 0.67 kW max power motor, the series offers two tailored variants: VB-1400V (delivering ultra-high airflow up to 145 L/min) and VB-1400H (achieving deep vacuum up to -740 mmHg / -98.6 kPa with 110 L/min flow). Maintaining a lightweight 7.85 kg aluminum alloy footprint and 56 dB(A) quiet operation, each unit features 100% oil-free performance, thermal overload safety, and a complete free installation kit.

Under 110V/60Hz, VB-1400V draws up to 0.67 kW (5.9 A) to achieve 145 L/min airflow, whereas VB-1400H draws 0.44 kW (3.9 A) for deep vacuum at 105 L/min. On 220V power grids, power consumption ranges between 0.35 kW and 0.55 kW depending on model variant and operating frequency.

Is the VB-1400 engineered for high-duty cycle industrial machinery like automated edge-banders?

Yes. Built with heavy-duty heat dissipation fins, S1 continuous duty motor windings, and internal thermal cut-off protectors, the VB-1400 handles multi-shift industrial automation, CNC suction tables, and edge-banding equipment with zero oil maintenance.

How often should intake filters and piston cup seals be inspected on the VB-1400 under continuous load?

Intake filter elements should be inspected every 500 operating hours and cleaned or replaced if clogged. High-performance PTFE piston cups typically require replacement after 6,000 to 8,000 service hours, depending on operating vacuum levels and ambient dust conditions.
