Busch R5 KB 0020 D Overview
The Busch R5 KB 0020 D is part of the established Busch R5 range of oil lubricated rotary vane vacuum pumps.
It is designed for confined machinery installations requiring reliable continuous vacuum performance, a nominal pumping capacity of 20 m³/h at 50Hz and an ultimate pressure of 2 mbar absolute.
The KB 0020 D is commonly installed in chamber packaging machines, clipping and sealing equipment, tray sealing and packaging machinery, vacuum handling systems and other compact production equipment requiring approximately 20 m³/h at 50Hz.
Oil within the pump lubricates the working components, assists sealing and helps control operating temperature. Integrated exhaust separation helps recover oil and reduce oil mist from the pump exhaust.
Vacuum Pumps UK can assist with the supply of a new Busch R5 KB 0020 D where the original pump specification needs to be retained.

Busch R5 KB 0020 D Pump Features
Oil Lubricated Rotary Vane
Oil provides lubrication and sealing within the pumping chamber while supporting stable vacuum performance.
Direct-Drive Construction
The direct-drive arrangement supports a reduced overall height and weight for installation in confined machinery spaces.
Compact Installation
The pump is designed for compact OEM machinery and vacuum packaging equipment where available installation space is restricted.
Oil Mist Separation
Integrated exhaust separation helps retain oil within the pump and minimise oil mist emissions.
Non-Return Protection
An integrated non-return arrangement helps prevent unwanted reverse flow when the pump stops.
Continuous Operation
The KB 0020 D is rated for continuous duty when correctly selected, installed and maintained.

DVP LC20
Comparable 20 m³/h oil lubricated vacuum pump
Comparable DVP Alternative
Consider the DVP LC20
Where an exact Busch replacement is not essential, the DVP LC20 may provide a suitable and cost-effective alternative to the Busch R5 KB 0020 D.
With a nominal capacity of 20 m³/h at 50Hz and 24 m³/h at 60Hz, the LC20 matches the stated pumping capacity of the Busch R5 KB 0020 D.
Both pumps have a stated final pressure of 2 mbar absolute, making the LC20 a closely aligned option where the application does not specifically require the original Busch model.
The DVP LC20 combines compact dimensions with low noise levels, straightforward oil inspection and simple routine maintenance.
Its oil damping and recovery system incorporates a by-pass and automatic float-operated oil recovery valve to help minimise oil vapour emissions from the exhaust. A sealing device also helps prevent oil from being drawn back into the connected system if the pump stops under vacuum.
Although the principal performance figures are closely matched, mounting dimensions, inlet position, connection size, motor voltage and installation arrangements must still be checked before changing pump model.
Vacuum Pumps UK is the UK and Ireland Master Agent for DVP Vacuum Technology.
Busch R5 KB 0020 D and DVP LC20 Comparison
