They are in use globally in a wide variety of applications. The principle of operation is very simple. VC Vacuum Pump Cross Section Suction Port Cooling Air Channels Discharge Port Discharge Filters Suction Filters Oil Sump VC Vacuum Pump Cross Section Large pumps, 400 m3/hr and over, run at low speed. 960 rpm @ 50 Hz V-Series: Rotary Vane Oil-lubricated Blades with long service life Optimised oil-water separation High water vapour capabilities Low noise level Easy to maintain Long up-times ONCE THROUGH OIL (OTO) LUBRICATED ROTARY VANE VACUUM PUMPS. OTO rotary vane vacuum pumps designed for process applications. They are in service worldwide, over 1000 in use in a broad range of applications. Anything from a simple pump to a complex system is available. Once Through Oil Lubricated Rotary Vane Vacuum Pumps From 10 to 1200 m3/hr for applications from Pilot Plant to Large Scale Production VLV VL VWZ Once Through Oil Lubricated Rotary Vane Vacuum Pumps VL The VL is a single stage pump. Capacities 10 to 100 m3/hr (50 Hz) 12 to 120 m3/hr (60 Hz) Ultimate vacuum 30 mbarA Air cooled. Integral fresh oil tank. Once Through Oil Lubricated Rotary Vane Vacuum Pumps VLB The VLB is a VL with a Base The pump is the same but is mounted on a base casting which includes a waste oil/condensate collection vessel and a discharge filter. A level switch is normally fitted in the discharge vessel to indicate high level. The Base is cast aluminium and can be Halar coated for corrosion resistance. VL Once Through Oil Lubricated Rotary Vane Vacuum Pumps VLV- 2 The VLV-2 is a two stage pump. Capacities 27 to 100 m3/hr (50 Hz) 32 to 120 m3/hr (60 Hz) Ultimate vacuum 0.5 mbarA Air cooled. The VLV-3 is available to special order Same capacities, 0.03 mbarA. VLV Once Through Oil Lubricated Rotary Vane Vacuum Pumps VLV- 2 The VLV has as standard •Integral fresh oil tank •Waste oil/condensate collection tank •Oil mist filter. •Fresh oil low level switch •Waste oil high level switch. •The base casting is cast iron and can be Halar coated for corrosion resistance VLV Once Through Oil Lubricated Rotary Vane Vacuum Pumps VWZ The VWZ is a two stage pump. Capacities 100 to 1200 m3/hr (50 Hz) 120 to 1440 m3/hr (60 Hz) Ultimate vacuum 0.5 mbarA Water cooled with radiator or direct water cooling. Once Through Oil Lubricated Rotary Vane Vacuum Pumps VWZ The VWZ has as standard. •Integral fresh oil tank •Fresh oil low level switch •Cooling water temperature switch Normal option includes an exhaust oil/condensate filter with high level switch. PFA or Halar coated exhaust filters are available for corrosion resistance. VWZ Operating Principle Cooling medium Vacuum connection By-pass valve Exhaust connection Fresh oil reservoir Oil pump Low pressure stage High pressure stage Once Through Oil Lubricated Rotary Vane Vacuum Pumps One common question is…. Why does it need a 2 stage VWZ to reach 0.5 mbarA when a single stage VC pump will do the same? The answer is simple, a VC pump has large quantities of oil circulating and has non-return valves. This allows high vacuum in a single stage. A “Once Through Oil” (OTO) pump uses only a small quantity of oil and has no non-return valves. Booster Groups VPA The VPA is a VWZ with a roots type booster. Capacities 485 to 4000 m3/hr (50 Hz) 590 to 4800 m3/hr (60 Hz) Ultimate vacuum 0.01 mbarA Larger capacities available on request. Although not in the catalogue, boosters can be fitted to the VLV. Once Through Oil Lubricated Rotary Vane Vacuum Pumps Advantages Disadvantages Relatively low cost Small amounts of oil in exhaust High efficiency Liquid ingress can cause failure High levels of vacuum Oil reaction with certain processes can cause problems Corrosive vapour handling with standard materials High solvent load can wash off oil. Simple to maintain, can be restored to “as new” performance. Running for long periods at rough vacuum (above 100 mbarA) can blow off the oil.( not VL or VLB) TWISTER DRY RUNNING SCREW VACUUM PUMPS The Twister VSA and VSB are dry running screw vacuum pumps designed for process applications.

Investment is moving towards Asia. If we work together we can benefit from the shift in investment. The Zephyr range has been expanded and improved, developments are continuing This presentation gives information on the new models and comparisons with some competitors products. Applications for Zephyrs, vacuum and pressure, are shown. The Zephyr uses rotary claw technology to develop vacuum and pressure. Its dry running, wear free, pumping action is extremely efficient and it requires very little maintenance. KLR DLR The Zephyr is available in 3 versions. Pressure - DLR Vacuum - VLR Pressure + Vacuum - KLR VLR KLR VLR and DLR KLR Vacuum up to 100 mbar (abs.) Overpressure up to +2.2 bar In combined operation simultaneous vacuum, up to 0.6 bar, and pressure up to +1.0 bar can be obtained. Capacities between 60 and 600 m³/hr Twin Claw Rotors Triple Claw Rotors Intermediate charging Suction air Pressure air Intermediate charging The triple claw KLR design is unique and allows simultaneous vacuum and pressure. Zephyr Applications • Medical Vacuum • Soil Remediation • Printing & Print Finishing • Biogas Compression • Paper Converting • Bottle Filling • Tobacco Industry • CD DVD Manufacture • Conveying • Poultry Evisceration • Water Treatment These are just some applications, there are many more. Biogas Recirculation in a Sewage Digester 1.2 to 1.8 barG typical In addition to Biogas circulation, the Zephyr is commonly used in low pressure compressed air sludge mixing applications Biogas Compression for Power Generation CD DVD Manufacture GD Taiwan have been successful in this industry. 10 VLR 500’s have been sold to one customer for 2 installations.
