Extend Service Intervals through cooler running, larger oil capacity, and internal surface protection.

• Cool running–cooler running slow down corrosive chemistry in pump oil
• Extend service intervals
• Large oil capacity: dilutes corrosive chemistry in pump oil
• Internal surface protection–oil case has PTFE coating; pump module has black oxide coating
• Extend pump maintenance intervals
• All the features you'd expect in a direct drive pump including–forced oil lubrication, anti-suck back valve, gas ballast

Welch® CRVpro™ direct drive rotary vane vacuum pumps are the new standard. Service intervals are extended by cooler running and larger oil reservoir. These two features reduce activity of aggressive chemistry trapped in pump oil. Service intervals are also extended because Pump oil reservoir has PTFE coating and pump module has black oxide coating. Plus, all the features you'd expect in a direct drive vacuum pump including forced oil lubrication, gas ballast, and anti-suck back valve.
