Pfeiffer Vacuum Duo 255 M Vacuum Pump, Dual Stage, 3-phase motor, 3TF, 230/400 V, 50 Hz; 265/460 V, 60 Hz, PKD48152 / PK D48 152
Pfeiffer DuoLine 255 M, 3-Phase Motor Rotary Vane Pump - Product Overview:
The Pfeiffer Duo 255 M (utilizing a three-phase motor) is a dual-stage rotary vane pump with a pumping speed of 255 cubic meters per hour (m^3/h).
DuoLine rotary vane pumps are ideally suited to cover applications in the low-to-medium vacuum range with pressures of up to 20^(-3) mbar. Our Pfeiffer DuoLine vacuum pumps offer reliable operation for critical industrial applications including drying processes, metallurgical processes, and resin potting and casting systems – serving either as a standalone pump or backing pump in our roots-pumping and turbo-pumping stations.
The use of a magnetic coupling minimizes maintenance requirements, contributing to considerable per-pump cost savings resulting from less-frequent maintenance intervals. The product likewise includes a temperature sensor (3TF) for enhanced protection.
The DuoLine 255 is a powerful vacuum, to be used exclusively for industrial applications. The product comes equipped with an integrated gas ballast and safety valve. Various motor voltages afford worldwide employment of the product. No non-ferrous metals are included within the DuoLine 255.
Pfeiffer Duo 255 (Three-Phase Motor) Key Features & Attributes:
- Dual-Stage, High-Performance Rotary Vane Pump w/ Pumping Speed of 255 m^3/h
- 3-Phase Motor for 190-210/330-365 V (± 5 %) 50 Hz or 200-230/360-400 V (± 5 %) 60 Hz Supply Voltages
- Integrated Temperature Sensor (3TF) for Optimum Motor Protection
- Integrated Gas Ballast and HV Safety Valve
- Ideally Utilized for Low-to-Medium Intensity Vacuum Applications
- Special Feature: Various Motor Voltages for Worldwide Standardization
Pfeiffer Rotary Vane Pumps - Technical Information:
Pfeiffer Vacuum manufactures some of the most widely-utilized varieties of advanced rotary vane used in a variety of industrial applications in the twenty-first century, including laboratory processes, chemical and process engineering, among others. These products are ideally utilized for the low-to-medium intensity vacuum range. Pfeiffer vacuum pumps are especially known for their durability and wide range of application.
A rotary vane pump functions as a displacement pump, creating a low-pulsation suction volume flow. Rotary vane pumps include an eccentrically-supported rotor with two rotating vanes, encased and revolving within a housing. The Pfeiffer Rotary Vane Pumps offered to our clients are oil-lubricated (wet-version pumps); these operating fluids help to enhance the insulation of pump components and ensure maximum durability and efficiency of the product.
We offer both single-stage and dual-stage Pfeiffer Rotary Vane Vacuum Pumps on our website. Single-stage pumps are the preferred choice for low-intensity vacuum applications, while dual-stage pumps are the recommended choices for the medium and upper intensity range of vacuum applications.
