Dangerous liquids must never be dispensed by simply pouring them out from a bottle, barrel or other container. Even the use of a funnel does not provide the required degree of safety when bottling dangerous liquids. Inadequate liquid dispense procedures can lead to:

• Increased accidental risk of slipping on wet or dirty floors
• Skin irritation or more extreme toxic effects from chemical spills
• Health hazards from harmful vapours

Bürkle offers a wide range of pumping devices for manually dispensing liquids from containers, canisters, drums and tanks.

Pump capacity

Electric pumps are the first choice for dispensing large quantities of liquid at a fixed location. Their higher pumping capacity saves time and requires less manual effort. However, the purchase of an expensive electric barrel pump is not always practical or economical; for example, there may no on-site electrical supply, especially outdoors or in a materials storage facility. So, manual pumps are an interesting alternative to electric pumps for filling off small quantities due to their independence from a power supply, and also at a much reduced cost.

Container size and container type

Pumps that work according to the excess pressure principle are suitable for dispensing required quantities from canisters and small drums up to a capacity of approximately 60 litres. Air is pumped into the container using a pumping ball or pumping piston. This creates excess pressure in the container and the liquid is forced out via the immersion tube.

When sampling, a small, randomly selected amount is taken from a larger overall quantity. These samples often serve as the basis for the quality assurance protocols, and so the correct procedure for taking spot samples is a critical matter, because only with representative and authentic samples can reliable information about the quality, properties or composition of a particular material be assessed.

Bürkle offers a wide range of disposable and sterile sampling equipment for bulk goods, liquids, viscous substances, soil, ice and meat with comprehensive accessories and ancillary products.
