Liquid Ring Vacuum Pumps Design
SPECK offers both single stage and two stage pumps with and without flap valves, with close-coupled and base plate versions. We engineer our mechanical seals to suit the demands of specific applications where requested, and can provide a double acting seal when required. Certail models, such as our VZ Series are also available with magnetic drive, allieviating the need for a mechanical seal altogether. SPECK offers various build materials such as Copper Alloy Cast Iron and Stainless Steel. Our base plate versions come with the option of material certificates, examination certificates and ATEX II IG IIB+H2 cbk TX, and the close coupled versions with ATEX II 2G cb TX
