PVR EU HWT 107-160-205
PVR EU HWT 107-160-205 is intended for industrial vacuum duties with elevated water-vapour loads where condensation control is a key selection factor. The EU 107 HWT, EU 160 HWT and EU 205 HWT group uses PVR rotary-vane technology to provide a defined relationship between pumping speed and operating pressure, which is central to equipment sizing. For engineers and maintenance teams, the key decision is to match the required pressure, gas load, operating frequency and vapour content to the correct version rather than select on flow alone.An oversized circuit and gas ballast reduce condensation risk when larger quantities of vapour are pumped. From EU 160 HWT upward, cooling combines an air-oil heat exchanger with a centrifugal fan; AxFlow Czech lists an ATEX option for EU 160 HWT.Verified technical data for PVR EU HWT 107-160-205 includes 110, 152 and 205 m³/h at 50 Hz and an ultimate pressure of ≤0.8 mbar with gas ballast. PVR specifies 0.8–850 mbar absolute, except EU 160 HWT which is specified for 0.8–400 mbar. The published range also includes water-vapour pumping capacities of 9, 9 and 9.8 kg/h at 50 Hz. These datapoints provide a selection basis, but the final operating point must be checked against the exact pump version and process conditions.Oil-lubricated rotary vane construction combines continuous lubrication with defined gas handling and serviceable components. Features such as check valves, oil-mist separation and gas ballast where fitted help protect restart behaviour, exhaust cleanliness and vapour handling, which can reduce avoidable maintenance events. AxFlow can support product selection, service and spare parts for PVR EU HWT 107-160-205; planned maintenance and correct variant selection help control downtime risk, process continuity and total cost of ownership.
