Bürkle Otal pumps are simple, reliable liquid handling and dispensing devices in polypropylene with a polyvinyl chloride stopper. Available with either hand- or foot-operated squeeze bulb and release button to interrupt the flow. The down tube is extendible and this enables the pump to be used with various sizes of bottles. Liquid is forced into the collecting vessel by squeezing the bulb and the flow can be instantly interrupted by pressing the release button. Excess liquid can be sucked back by pumping and operating the release button. For use as a siphon additional tubing must be attached to the outlet tube and after pumping the liquid will flow continuously. Mounted on a 3-part, PVC stopper to fit openings as indicated. Not suitable for pumping highly flammable liquids.
|Static Electricity Hazards Attention is drawn to the need to use correct procedures to prevent any potential ignition hazards due to the accumulation of static electricity charges during pumping. Correct procedures are described in BS5958 ‘Control of Undesirable Static Electricity’: Part 1 ‘General Considerations’ and Part 2 “Recommendations for Particular Industrial Situations’. In general there is a need to earth-clamp all metal parts of the pumping system, e.g. drum, pump tube and receiving vessel, using an earth conductor having a resistance to earth of not more than 10 Ohm. The use of plastic drums or vessels may increase the potential risks and their use in hazardous areas or with hazardous liquids should be carefully considered in the light of the recommendations of BS5958.|
