Atlas Copco AWC 160 – liquid ring pump for harsh, humid processes
The AWC 160 delivers 165 m³/h at 50 Hz and 185 m³/h at 60 Hz (saturated air) and reaches 33 mbar(a). The flat port plate with variable port opening keeps the delivery capacity stable over the whole rough vacuum range and saves operating water. Inlet and outlet DN 50, operating water connection Rp 3/4, dimensions 699 × 303 × 361 mm (L × W × H), weight 108 kg.Why liquid ring?
In the pump an eccentrically mounted impeller rotates a ring of water, which seals the chambers and compresses the gas. In the process, the water absorbs the heat of compression – vapour, condensate, entrained liquid and particles hardly disturb operation.Applications of the range
Atlas Copco lists plastics extrusion, expanded polystyrene (EPS), filtration, degassing, the evisceration of meat and poultry, and drying.Variants of the AWC 160
Ehrler & Beck supplies the AWC 160 with a dual-frequency motor for 50 and 60 Hz (versions for Europe/China and for Korea/Japan), with a 50 Hz motor 380 V and without motor with lantern flange for a 50 or 60 Hz motor – in each case in grey cast iron with stainless steel impeller, entirely in stainless steel SS 304 or in SS 316L.Features of the AWC range
- Single-stage liquid ring pump with flat port plate and variable port: stable delivery capacity over the whole rough vacuum range with economical operating water consumption
- Water as operating liquid: isothermal compression, insensitive to vapour, condensate, liquid carry-over and particles
- Impeller made of stainless steel as standard, corrosion-resistant
- Version with mounted motor and lantern flange: automatic motor alignment and automatic adjustment of the liquid level to the shaft centre line during filling
- Compact pump element, robust and proven design
