The robust vacuum pump CRVpro 16 belongs to the new high-performance two-stage rotary vane pumps generation of Welch. The pump impresses with its long service life, absolute reliability and its low maintenance requirements.


This has been enabled thanks to 3 major innovations: 

  • Its low running temperature, which slows down potential corrosion processes and reduces the oil consumption. 
  • Its large oil reservoir ensures a low chemical concentration, which contributes to the prolongation of the oil exchange intervals. 
  • Its special inside coating increases the chemical resistance of the pump. 

Scope of delivery: Pump with motor, 3 line cords (EU/UK/US), 3 liters of oil, centering ring with dirt trap, centering ring, 2 clamping rings.
