Busch R5 RA 1000 B Overview
The Busch R5 RA 1000 B is part of the established Busch R5 range of oil lubricated rotary vane vacuum pumps.
It is a large single-stage pump developed for continuous-duty industrial applications requiring high pumping speed at low operating pressures and a nominal capacity of 1000 m³/h at 50Hz.
The RA 1000 B is suited to large packaging and food processing lines, plastics machinery, vacuum conveying equipment, centralised vacuum installations and other high-demand production processes where vacuum performance and production uptime are important.
Oil within the pump lubricates the working components, assists sealing and supports stable operating temperature. Integrated exhaust separator elements recover oil within the pump and help reduce oil mist from the exhaust.
Oil lubricated rotary vane pumps should not be allowed to run open to atmosphere for prolonged periods, as the high gas flow can rapidly load and saturate the exhaust separator elements.
Vacuum Pumps UK can assist with the supply of a new Busch R5 RA 1000 B where the original pump specification needs to be retained.

Busch R5 RA 1000 B Pump Features
Single-Stage Rotary Vane
The single-stage oil lubricated rotary vane design provides strong pumping performance at low operating pressures.
Continuous Industrial Duty
The RA 1000 B is designed for continuous operation when correctly installed, operated and maintained.
High-Capacity Performance
A nominal pumping speed of 1000 m³/h at 50Hz supports large production machinery and high-demand vacuum installations.
Oil Mist Separation
Integrated exhaust separator elements help retain oil within the pump and reduce oil mist from the exhaust.
Low-Pressure Performance
The stated ultimate pressure of 0.1 mbar absolute supports applications requiring a relatively deep industrial vacuum.
Separator Protection
Correct system control is important because prolonged operation open to atmosphere can quickly load the exhaust separator elements.

Busch R5 RA 1000 B Frequently Asked Questions
What type of vacuum pump is the Busch R5 RA 1000 B?
It is a large single-stage oil lubricated rotary vane vacuum pump designed for continuous high-capacity industrial applications.
What is the capacity of the Busch R5 RA 1000 B?
The stated nominal pumping capacity is approximately 1000 m³/h at 50Hz and 1200 m³/h at 60Hz.
What ultimate vacuum does the Busch R5 RA 1000 B achieve?
The stated ultimate vacuum is 0.1 mbar absolute at both 50Hz and 60Hz.
Can Vacuum Pumps UK supply a new Busch R5 RA 1000 B?
Yes. Vacuum Pumps UK can supply new Busch R5 RA 1000 B vacuum pumps, subject to specification and availability.
Can you offer an alternative to the Busch R5 RA 1000 B?
Yes. Where an exact Busch replacement is not essential, we can assess the application and offer a suitable alternative pump or engineered vacuum pump system.
Would the alternative necessarily be one large pump?
Not necessarily. Depending on the process and production requirements, the most suitable solution may be one large pump, a duty and standby arrangement or a modular multi-pump system.
Is an alternative pump or system a direct replacement?
Not necessarily. Pumping performance, operating pressure, dimensions, connections, motor details, controls, cooling and process conditions should be checked before changing pump or system configuration.
Why should the pump not run open to atmosphere?
Prolonged operation open to atmosphere creates a high gas flow through the pump and can quickly load or saturate the exhaust separator elements.
Can you supply Busch service parts?
Yes. Service kits, filters, separators, oils and other Busch pump components are available through our sister company VacAir Superstore.
Can my existing Busch RA 1000 B be repaired?
Many pumps can be serviced or overhauled depending on their internal condition. VacAir can provide specialist Busch pump inspection, repair and refurbishment support.
