A new range of single and two-stage liquid ring vacuum pumps, are available in construction materials to suit almost any process use involving aggressive or corrosive vapours
Rietschle (UK) is entering the liquid ring vacuum pump market with Barracuda: a range of single and two-stage pumps, which are available in construction materials to suit almost any process use involving aggressive or corrosive vapours.
Using cold water - or an alternative sealing fluid - to deliver oil-free gasses (dry or humid), their robust design allows them to handle contaminated or saturated vapours, or occasional slugs of liquid.
Barracuda V series pumps are close-coupled, single stage designs offering ultimate vacuum of 33 mbar(A), and a continuous, non-pulsating vacuum supply.
Suction capacities range from 9.5m3/h on the smallest V6, up to 380m3/h on the largest model V430.
In effect, the V series offers the capacity of a single stage pump, with the ultimate vacuum normally only available from a two-stage pump.
The V series can be supplied in cast iron with a stainless steel or bronze impeller, or alternatively in all stainless steel.
Barracuda VH are long-coupled, two-stage, liquid ring vacuum pumps with separate motors.
They also offer ultimate vacuum of 33mbar(A), but with suction capacities ranging from 20 to 1590m3/h.
The VU series are long-coupled, single stage designs with an ultimate vacuum of 150 mbar(A), and suction capacities from 20 to 435m3/h.
Both the VH and VU series are available in all bronze construction (with stainless steel shaft), or in the same choice of materials as the V series.
A range of accessories from suction non-return valves to discharge air-liquid separators is also available, in a choice of materials.
Rietschle can also supply complete vacuum packages to specific requirements: with higher vacuum levels and re-circulated seal systems with intercoolers, to reduce environmental load and water consumption.
