Engineering standards and 60 years of PVR vacuum expertise

Italian engineering specialist PVR S.r.l. has developed vacuum technology since 1964. Operating as part of the industrial machinery group Ingersoll Rand, PVR combines European manufacturing standards with modern quality control protocols.

Each pump undergoes rigorous performance testing on factory benches to verify ultimate vacuum levels, volume displacement speeds, and dynamic vibration profiles.

Balanced rotor assemblies, wear-resistant metal alloys, and high-grade fluoroelastomer seals ensure high operational life during round-the-clock plant shifts.

Technical selection for PVL and EU oil-lubricated rotary vane pumps

Oil-lubricated rotary vane pumps of the PVL and EU families represent the core product offering for medium and rough vacuum duties. Single-stage units achieve reliable vacuum levels down to 0.5 mbar across pumping speeds from 110 to 790 m3/h.

An integrated gas ballast valve prevents water vapor condensation within the oil reservoir, proving essential for industrial drying, thermoforming, and food packaging machinery.

Multi-stage exhaust oil mist separators remove airborne droplets to maintain clean workspace environments and minimize periodic lubrication top-ups.

Oil-free claw pumps DRY C and dry screw units SCREWVAC

For industrial manufacturing processes that require absolute freedom from lubricant contamination, PVR manufactures DRY C claw pumps and SCREWVAC dry screw machines.

DRY C units operate via non-contacting synchronized profile rotors, eliminating mechanical friction inside the pumping cavity and removing the need for oil replacement. SCREWVAC dry screw pumps utilize variable pitch hybrid rotors to improve thermodynamic compression efficiency.

These resilient dry machines resist corrosive solvent vapors across chemical synthesis and active pharmaceutical drying.

Dual-stage PHV-K pumps engineered for fine vacuum levels

When production lines demand deep ultimate vacuum down to 0.001 mbar, PVR PHV-K two-stage oil-sealed rotary vane pumps provide dependable performance. Two sequential compression cavities in series ensure continuous pumping throughput at fine vacuum limits.

Pressurized mechanical oil circulation delivers efficient thermal dissipation and reduces friction wear across rotating shaft journals.

An integrated electromagnetic anti-suckback valve shuts instantly during unexpected electrical power loss, protecting upstream customer pipe networks from backstream oil ingress.

Roots vacuum boosters and compact dry vane monoblock pumps

To multiply volumetric pumping speed in deep vacuum regimes, PVR offers Roots mechanical vacuum boosters handling displacements up to 61200 m3/h.

Functioning alongside backing vane or screw pumps, Roots units rapidly evacuate large autoclave vessels, degassing furnaces, and thin-film coating chambers. For compact automated workstations, PVR provides dry vane monoblock pumps with flow capacities from 3 to 48 m3/h.

Self-lubricating graphite vanes yield whisper-quiet operation and minimal structural vibration without requiring liquid lubricants.

Centralized vacuum station engineering and preventive maintenance

PVR engineers modular central vacuum stations featuring duplex or triplex pump groups mounted on horizontal steel receivers from 500 to 1000 liters.

A PLC automation cabinet coordinates sequential pump starts according to realtime factory vacuum consumption, yielding significant electrical energy savings.

To guarantee continuous uptime throughout multi-shift manufacturing, standardized preventive maintenance overhaul packs are provided: graphite and composite vanes, exhaust oil mist separators, air intake cartridges, and precision flange gaskets.
