Frequently Asked Questions (FAQ)
Q1: What is the recommended oil type for the BUSCH RA 0520 A pump?
We recommend using BUSCH original vacuum oil VSB 100 or equivalent mineral oil with a viscosity of ISO VG 100. Always refer to the manual for exact specifications.
Q2: How often should I change the oil?
Under normal operating conditions, oil change is recommended every 3,000–5,000 operating hours. However, if the pump is exposed to high dust or aggressive media, more frequent changes may be required.
Q3: Can this pump handle corrosive gases?
The standard RA 0520 A is designed for clean, dry air and non-corrosive gases. For corrosive applications, please consult us for special material options (e.g., stainless steel or coated internals).
Q4: What is the maximum ambient temperature for operation?
The pump can operate at ambient temperatures from 0 °C to 40 °C. For higher temperatures, a derating in performance may be necessary.
Q5: Is the pump suitable for continuous 24/7 operation?
Yes, the R5 series is designed for continuous duty. The oil-lubricated system ensures reliable cooling and sealing even in long-running applications.
Q6: What is the noise level at typical operation?
The noise level is approximately 58 dB(A) at 50 Hz, which is relatively low for an industrial vacuum pump. For even quieter operation, exhaust silencers can be added.
Q7: What warranty do you offer on this pump?
We provide a standard 12-month warranty from the date of shipment. Extended warranty options are available upon request.
Q8: Can I get the pump with a different motor voltage?
Yes, we offer motors for 208–230V, 380–460V, 50/60Hz, and other voltage configurations as per your requirement. Please specify when ordering.
