Vacuubrand RZ 2.5 Dual Stage, Dual Voltage High Performance Vacuum Pump, 1.7 CFM RZ 2.5, 120 VAC - 60Hz, 20798126
This is the current revision of the previous version p/n 20698126
Vacuubrand RZ 2.5 Overview:
The Vacuubrand RZ 2.5 dry vacuum rotary vane pumps. The max pumping speed up to 1.6 CFM at 60 Hz. Vacuubrand (20698126) has the nominal rotation speed 1800 min-1 at 60 Hz. The weight of Vacuubrand RZ 2.5 is 11.4 kg. Noise level Vacuubrand RZ 2.5 is 43 dB at 50 Hz.
The one-stage RE 2.5 and two-stage RZ 2.5 are high-performance rotary vane pumps with extra compact design and low weight. They are the ideal solution for a wide range of laboratory and process applications that require low ultimate vacuum at medium gas flow rate. The rotary vane pumping unit PC 3 with cold trap (GKF 1000i) at the inlet helps the pump to handle larger volumes of condensable vapors. The pumping unit is compact, user-friendly, and well-arranged, with oil mist filter at the outlet, a valve, and a T-connection for a gauge. The RZ 2.5 is also available combined with the oil mist filter (FO) and the VS 16 valve as a package.
Vacuubrand RZ 2.5 Features:
- Single Stage, High Performance Rotary Vane Pump
- High flow rates even at vacuum levels approching ultimate vacuum
- High water vapor tolerance due to efficient gas ballast
- Very good ultimate pressure even with gass ballast
- Vacuum tight at switch off; external andi-suckback valve not needed
- Large oil volume: long intervals between oil changes
- Ease of maintenance due to telescopic design
Vacuubrand RZ 2.5 Applications:
Typical applications for Vacuubrand RZ 2.5 include lypohilization, vacuum distilation and evacuation of small valumes, u-focus, xray tubes or filling with purge gases. Vacuubrand RE 2.5 with PC 3 is a perfect choice for applications requiring special protectionof pump and enviroment.
