Dry compression keeps sealing oil out of the pumping chamber. Bearings and gears still require the specified lubricant. Purge and gas ballast protect the pump and help with suitable vapour loads, but change the attainable pressure. Provide gas composition, condensable load, dust and operating pressure before selection.
The manual identifies the lowest rating as ultimate partial pressure. Rotor purge raises it to 0.01 mbar and gas ballast to 0.1 mbar, both ±10%. Inlet shaft-seal purge produces a different pressure again. The process protection requirements determine which operating condition is appropriate.
Specify the 400 V three-phase configuration for the relevant UK industrial supply. Frequency-converter and control arrangements depend on the order reference; rack-mounted “-r” versions are distinct builds. Fieldbus modules, external displays, non-return valves, silencers, inlet protection and booster adapters are selected separately unless included explicitly in the quotation. Select washdown FP or process-specific versions separately.
Provide duty cycle, working pressure, throughput, cooling-water conditions, exhaust back pressure, footprint and available power. Ultimate pressure is a manufacturer test value, not a guarantee at the chamber. Preserve service access and observe the full cooling-water and purge requirements in the instructions.
