The Wordfik PVX series is a complete portfolio of single-stage oil-lubricated rotary vane vacuum pumps, spanning from compact 16 m³/h (9.4 CFM) OEM units to heavy-duty 630 m³/h (371 SCFM) industrial models, with ultimate vacuum from 1 mbar down to 0.1 mbar. Designed as direct drop-in replacements for the full Busch R5 oil-sealed rotary vane pump portfolio, every unit shares a proven lubricated vane sealing architecture with premium synthetic vacuum oil.
All PVX pumps deliver stable deep vacuum with excellent water vapor tolerance, making them the most versatile and cost-effective vacuum solution for general industrial applications. The entire range adheres to a unified premium build standard – including heat-treated cast iron cores, FKM fluororubber seals and high-efficiency copper motors – ensuring consistent reliability, long service life and low maintenance cost across every size. With broad global voltage compatibility and standard CE certification, the series serves over 80 countries across packaging, froming, degassing, transformer manufacturing and medical sectors.
Features:
Full 16–630 m³/h Product Lineup
12 models covering micro, small, medium, large and ultra-large flow tiers, with ultimate vacuum from 1 mbar to 0.1 mbar. Enables precise sizing for any application from desktop equipment to factory-wide central systems.
Proven Oil-Sealed Deep Vacuum Technology
Oil-lubricated vane sealing delivers stable deep vacuum far superior to dry vane pumps. Ideal for processes requiring high vacuum level such as degassing, drying, distillation and impregnation.
Uniform Premium Build Quality
Heat-treated cast iron cylinder and rotor, premium FKM fluororubber seals and high-efficiency full-copper motors are standard across the entire range. Guarantees consistent performance, corrosion resistance and leak-free operation regardless of pump size.
Full Busch R5 Equivalent Replacement Range
Every PVX model matches mounting dimensions, port sizes and performance parameters of corresponding Busch R5 series pumps. Enables direct drop-in replacement across the entire Busch lineup with no system modifications.
High Water Vapor Tolerance
Integrated gas ballast valves on all models deliver excellent water vapor handling, from 0.5 kg/h on small units to 7.5 kg/h on large models. Reliable performance in moist process environments.
Global Certification & Wide Voltage Support
Broad single-phase and three-phase voltage options, with dual 50/60Hz support on most models. Standard CE certification, optional UL-approved motors available for North American markets.
Low Total Cost of Ownership
Highly affordable, readily available spare parts and long service intervals minimize long-term operating and maintenance expenses. Delivers industry-leading value for continuous industrial operation.
In-Stock Availability & Unified Support
All standard models are fully stocked for fast global shipping. Backed by 1-year standard warranty (2 years on PVX250+ flagship models), lifetime after-sales service and 7/24 technical support.
