RZ 9 Rotary Vane Pump

The RZ 9 Rotary Vane Pump is a two-stage pump designed for the efficient evacuation of vessels at higher gas flow rates. It is commonly used in applications such as lyophilization, vacuum distillation, and drying chambers. The pump is dependable and easy to maintain, providing steady performance in various laboratory settings.

Features

• Consistent Flow Rates: Maintains high flow rates even as the vacuum level approaches its limit.
• Gas Ballast System: Designed to handle water vapour effectively, achieving a reliable vacuum with the gas ballast.
• Vacuum Integrity: Remains vacuum-tight upon shutdown, eliminating the need for an external anti-suckback valve.
• Oil Capacity: The large oil reservoir allows for extended intervals between oil changes.
• Maintenance-Friendly: The telescopic design simplifies routine maintenance tasks.
• Vacuum Performance: Reaches an ultimate vacuum of 2 x 10⁻³ mbar, or 1 x 10⁻² mbar with gas ballast.
• Pumping Capacity: Offers a maximum pumping speed of 8.9 m³/h at 50 Hz.

Application and Use

The RZ 9 Rotary Vane Pump is suited for tasks requiring reliable vacuum generation, such as freeze-drying, fine distillation processes, and operation of drying chambers. Its design supports consistent operation with minimal maintenance, making it a practical choice for laboratory and industrial environments.

Additional Options

The RZ 9 can be equipped with accessories like the exhaust filter FO and valve VS 25, offering a more tailored solution depending on the specific application needs.
