Bürkle foot-operated solvent pump with outlet hose and tap, 5603-3000

The Bürkle solvent pump, featuring foot operation, a discharge hose and a shut-off valve, represents a high-purity, occupational safety-optimised system solution for the contamination-free transfer and filling of organic solvents, acids, alkalis and flammable liquids from drums and large containers. In industrial production facilities, chemical laboratories and pharmaceutical filling plants, handling highly volatile or flammable media places the highest demands on explosion protection and ergonomics. Through the consistent use of chemically inert materials such as stainless steel and PTFE (Teflon), the purity of the filled media is fully preserved. For laboratory managers, health and safety officers and procurement staff in the B2B sector, this foot-operated pump offers the highest level of process reliability, as it enables precise, drip-free dosing whilst keeping the operator’s hands free to hold the target vessel.

Ergonomic foot operation for maximum occupational safety

The mechanical system architecture is characterised by convenient foot operation via a separate, robust foot bar. Activating the pump with the foot builds up a transient overpressure in the container, which delivers the liquid gently and evenly upwards through the riser tube. This contact-free operation offers a decisive advantage in terms of occupational safety: the operator has both hands free to position measuring cylinders, flasks or canisters precisely beneath the spout. This effectively minimises accidental spillage or dangerous splashes of corrosive chemicals during daily field use.

Material inertness for high-purity media

All functional components of the drum pump that come into contact with samples and media are manufactured from materials of the very highest quality. The robust immersion tube and the media-carrying valves are made of high-purity type 1.4301 (AISI 304) stainless steel, whilst all seals and the flexible outlet hose are made of chemically unrivalled PTFE. This material-science specification guarantees universal resistance to highly aggressive organic solvents such as acetone, ethanol, methanol or toluene. As the pump is designed to be completely free of lubricants or plastics containing plasticisers, high-purity sample quality is permanently guaranteed without any cross-contamination from the materials.

Gas-tight seal and controlled drainage of residual quantities

The Bürkle solvent pump is securely and airtightly fixed in the container’s bunghole via a highly stable drum coupling. This gas-tight system seal reliably prevents harmful solvent vapours from entering the ambient air and the breathing zone of laboratory staff during the pumping process. The flexible, 1.2-metre-long PTFE outlet hose is fitted with a precision stainless steel shut-off valve. This valve allows for absolutely precise, drip-free dispensing of even the smallest volumes. Thanks to the infinitely variable height-adjustable drum thread, the pump’s immersion depth can be perfectly adapted to the specific container geometry, ensuring excellent drainage of residual quantities.

Custom requirements & accessories

When dispensing highly flammable and combustible solvents (such as petrol, toluene or isopropanol), friction can generate dangerous electrostatic charges. To ensure explosion protection in accordance with strict health and safety guidelines, the use of a suitable anti-static kit is essential. Our range includes the original Bürkle anti-static kit (earthing cable with brass clamps), which safely dissipates electrostatic energy to earth in a way that is gentle on materials and ensures process reliability. For use with plastic drums, sheet metal containers or other containers, we also offer a comprehensive range of threaded adaptors (e.g. for Mauser threads, Tri-Sure or 2-inch coarse threads). Please make use of our technical procurement service to ensure the safe configuration of your hazardous materials workstation.
