Delivering up to 300 m³/h pumping speed at 60Hz, the 5.5 kW power core ensures fast chamber drawdown times for large-scale production cycles.
Features high-rigidity precision cast iron to absorb vibration, complemented by durable KSK oil seals engineered for high thermal limits up to 88°C.
Integrated oil circulation system provides efficient internal heat dissipation, preventing oil degradation and extending internal vane service life.
Tailor motor voltage ratings, brand configurations, specialized surface finishes, and intake port fittings to seamlessly integrate into custom machinery builds.
The V-250 delivers dynamic performance across global power grids: operating at 50Hz (1440 rpm) it achieves a displacement of 250 m³/h, while at 60Hz it ramps up to 300 m³/h for high-throughput evacuation.
Constructed with precision-machined heavy cast iron and equipped with high-temperature KSK oil seals, the V-250 maintains exceptional structural rigidity, leak tightness, and reliable thermal dissipation at continuous operating temperatures up to 88°C.
GOFLEX provides tailored solutions including customized motor voltages (3-phase 220V/380V/440V/460V), motor brand selection, custom paint finishes, specialized intake filtration assemblies, and branding configurations for original equipment manufacturers.
Routine maintenance is straightforward and cost-effective, requiring visual oil level checks via the sight glass, scheduled oil changes using ISO VG 68 vacuum oil every 500 to 2,000 operating hours, and regular exhaust filter inspection.
