The new E-Series Elliptical pumps from Becker challenge the adage that there’s nothing new in the world.
The E-Series pump is a new concept in pump design, combining one rotor and two compression chambers to yield a pump with 4 specific configurations: 2 Vacuum pumps; 2 compressors; independent pressure and vacuum pumps; or 2 combined pressure/vacuum pumps.
In the EPV series, the piston for the first time turns in an elliptical housing: instead of creating a single compression chamber as hitherto, this produces two independent ones. These can be combined in numerous ways or used separately from each other. Whether in the vacuum, pressure, combined or even double-combined pressure/vacuum operating mode, virtually everything is possible.
What’s more, the compression chambers can be of different sizes to meet specific customer needs. Need more blast air flow than vacuum? No problem. More vacuum flow than pressure? We can do that, too. The EPV series covers a delivery range of 2x40m³/h to 2x100m³/h and attains a final vacuum of 100 mbar absolute as well a pressure of +2.0 bar.
Unlike twin-shaft vacuum pumps and compressors, these units are 100% oil-free in the way they work (no drive gear). The single-shaft design and the number of compression chambers guarantee low-pulsation suction and/or blast air as well as low noise. These pumps are truly oil-less, unlike other pumps that say they are, but still require oil. Noise levels have been reduced by using lower rotational speeds, and employing sound deadening shrouds all around the pump. These shrouds double as air manifolds.
The revised design and modified piston/housing configuration give the rotary vanes a service life of over 20,000 hours. Significantly larger filter areas lead to noticeably longer maintenance intervals, also for the intake filters. In addition, the degree of filter soiling can simply be identified through a transparent filter cover.
Wide voltage range motors mean that delivery can be faster because one motor covers most voltages in use worldwide, which eliminates special orders.
We’ve integrated all the accessories to save space and make installation easier: vacuum and pressure regulating valves, blast air coolers, inlet filters, dust separators, and silencers.
Finally, a single E-Series elliptical pump can replace as many as four individual pumps, depending on your application.
