Claw pumps VKL/DKL Cost of Ownership The VKL/DKL claw range of Baratti Engineering generates contact-free vacuum or compressed air efficiently and economically. This is possible because of the principle of positive displacement. The gas becomes precompressed within the compressing chamber and is then discharged. This leads to a higher compression ratio compared to rotary lobe blower designs without internal compression at high vacuum and high overpressure.  Assemblies:  → Claw pump VKL/DKL  → Claw pump Accessoires Datasheets, dimension sheets and charateristics of all assemblies you can find in the → Download-Center.  Wide spectrum of performance A wider spectrum of performance and higher differential pressures can be achieved. The following ultimate pressures are attainable during continuous operation. Vacuum up to 40 mbar (abs.) for intermittend operation and up to 60 mbar (abs.) for permanent operation. Pressure up to 2.2 bar (g). A high efficiency is obtained over a wide pressure range. Reliability The two claw rotors are synchronized by a precision gear. Special seals separate the compression chamber and gear. The sealing area can be pressurized by adding a sealing gas. A gas tight, pressure shock resistant version is also available. A further advantage of the VKL/DKL types 60 to 150 is the overhung rotor design: • no second shaft te B-end • no re-greasing ofo atmosphere • no shaft seal at th bearings • fewer individual parts; easy to assemble • compact design The claws of the VKL/DKL range have an optimized, high precision shape and turn together without contact, synchronized by the gear. Therefore seal fluid within the compression chamber is not necessary. The compression is achieved dry and wear free. Wear sensitive discharge valves, as in other compressor designs, are not necessary. Compression in the multi-claw rotor is very symmetrical compared with single claw rotor designs. The VKL/DKL range is protected against overload by a safety valve or vacuum regulating/relief valve. All claw units are supplied with a stable, well designed steel cover. This cover enhances the cooling effect as well as providing reduced noise together with the included silencer.
