Becker U4.250 SA/K Rotary Vane Pump, 173 SCFM, 0.375 Torr, Oil Flooded Vacuum Pump, 208/230/460 V, 3 phase, U4.250 SA/K

Becker U4.250 SA/K Rotary Vane Pump, 173 SCFM, 0.375 Torr, Oil Flooded Vacuum Pump, 208/230/460 V, 3 phase, U4.250 SA/K

Becker U 4.250 SA/K Overview:

The Becker U 4.250 SA/K vacuum rotary vane pumps. The peak pumping speed up to 173 SCFM at 60 Hz. U 4.250 SA/K has the nominal rotation speed 1735 rpm at 60 Hz. The weight of U 4.250 SA/K is 243 lbs. Noise level U 4.250 SA/K is 76 dB at 60 Hz. Three phase with main requirement voltage 208/230/460 V at 60 Hz.

The Becker U 4.250 SA/K is oil flooded rotary vane vacuum pump with two stage oil separation, pressure differential lubrication, integrated anti-suck back valve, air-cooled oil cooler, horizontally mounted external inlet filter, initial charge of Becker’s synthetic oil, and coupled to a 10 HP, 208/230/460 volt, 3 phase, 60 Hz., TEFC motor.

The Becker U 4.250 SA/K rotary vacuum pumps are cool running, quiet, and highly efficient.

Providing vacuum to 29.9 in.Hg (0.4 Torr), our compact, direct-drive, oil-flooded pumps operate on a semi-synthetic oil and offer gas ballast as an option. Our multi-stage oil separation system is 99.9+% efficient.

If you want reliability and durability combined with industry-leading performance, you want a Becker rotary vacuum pump.

The Becker U 4.250 SA/K gas ballast valve (as standard from U 4.250 SA/K and with increased volumetric flow as an option) prevents the condensation of steam as far as possible. The gas ballast lets a measured amount of fresh air enter the compression chamber. By mixing saturated intake air with unsaturated fresh air, condensing is kept to a minimum. In addition, the protective cover supplied as standard minimises noise emissions.

An optional water cooling system allows the pump to be operated in higher ambient temperatures or with higher intake temperatures; the service life of the lubricant is also significantly increased. A wide range of accessories complements the pump, making it ideal for various tasks.

Applications include the graphic arts, packaging, vacuum chucking, robotics and material handling, medical/surgical, and air sampling among others.
