The CRVpro family of pumps is designed for high-performance and durability in demanding vacuum applications. These pumps feature advanced engineering and chemical-resistant design elements, making them ideal for use in laboratories with aggressive chemicals, high temperatures, and continuous operation.

Key Features:

• Superior Cooling: The CRVpro is cooler than comparable pumps, slowing down the rate of corrosion, increasing the lifespan of the pump, and improving reliability.
• Larger Oil Capacity: With a 40% larger oil capacity than comparable pumps, it effectively dilutes aggressive chemicals and extends the time between oil changes, reducing maintenance costs.
• Chemical-Resistant Coating: The oil case and pump module are coated with a chemical-resistant layer that protects non-moving parts from corrosion.
• Advanced Protection Mechanisms: The pump includes a gas ballast, forced oil lubrication, an anti-suckback mechanism, and thermal overload protection, ensuring smooth, reliable performance in demanding environments.

Suitable Applications:

• Freeze drying
• Degassing
• Vacuum ovens
• Concentrators

The CRVpro is ideal for various laboratory uses but is not recommended for applications requiring sustained operation above 30 torr, such as filtration, aspiration, and drying electrophoresis gels.

Technical Specifications:

• Model 3081-01:
  • Wired for 115V, 60Hz operation (North American standard)
  • Includes a North American line cord, vacuum inlet hose barb (suitable for 5/8" to 3/4" ID gum rubber hose), and a charge of oil.
• Model 3082-01:
  • Wired for 230V, 60Hz operation (North American standard)
  • Includes a 230V North American line cord, UK cord, and skuko cord, along with a charge of oil.

Note: Direct drive pumps like the CRVpro are not suitable for applications requiring operation above 30 torr.
