The barrel pump is also suitable for transferring ultra-pure liquids. The stopcock prevents hazardous vapours from escaping, and stops dripping after trans- fer. Barrel pump with rigid discharge tube with stopcock made of PTFE or with flexible discharge hose made of PTFE, length of 1.2 m and stopcock made of PVDF. • Immersion tube Ø 32 mm • All valves are made of solid PTFE/PVDF • Top quality – 3 years’ warranty • Barrel screw joints for commercially available containers available as accessories 1 PTFE barrel pump Ultrapure – discharge tube Immersion depth mm Delivery rate/stroke ml Immersion tube Ø mm Order No. 400 180 32 10 04 56040 600 270 32 10 04 56060 950 400 32 10 04 56061 2 PTFE barrel pump Ultrapure – discharge hose Immersion depth mm Delivery rate/stroke ml Immersion tube Ø mm Order No. 400 180 32 10 04 55640 600 270 32 10 04 55660 950 400 32 10 04 55661 Barrel connectors Article Order No. 3 Barrel coupling made of PP for R2 ″ , steel barrel female thread 29 05 12113 4 Barrel coupling made of PP for Mauser 2 ″ , coarse female thread 29 05 12115 5 Barrel coupling made of PP for Tri-Sure, coarse female thread 29 05 12116 6 Barrel stopper made of PVC for container openings with Ø from 40 to 70 mm 29 05 12114 w e b c o d e WWR4Q042 8 Stainless Steel Pumps, BÜRKLE Foot operated solvent pump made of stainless steel for ultrapure liquids. The medium only comes into contact with stainless steel and PTFE. The barrel screw joint and the stopcock mean that the container and pump can be sealed hermetically to prevent unwanted vapors from escaping after the filling process. • Stepless adjustment of immersion tube length • For ultrapure solvents • Rigid discharge tube with stainless steel/PTFE stopcock or discharge hose • For stainless steel drums with R 2 ″ connecting piece • 5-year warranty Article Immersion depth max. cm Flow rate l/min Tubing Ø mm Order No. 7 Foot operated solvent pump with discharge tube 95 20 18 10 04 50311 8 Foot operated solvent pump with discharge hose 95 20 18 10 04 50330 Hand operated solvent pump For contamination-free removal of organic solvents and flavouring substances. Compat- ible with the stainless steel drums 10 l and 25 l with R 2 ″ fine thread, which are common- ly used in laboratories. The pump is gas-proof and completely lockable by means of 2 ball cocks. Parts which have contact with medium are made of stainless steel, seals made of PTFE. • Stepless adjustment of immersion tube length. Vers.
