Suction lances with float switches for removing media from containers

A suction lance is a system for extracting liquids from canisters, barrels, or IBC containers. It is used to safely convey media such as chemicals, water, cleaning agents, or cooling lubricants while simultaneously monitoring the fill level. Suction lances are typically used in dosing systems, pump systems, and industrial machines.

An integrated float switch prevents a dosing pump from running dry. As soon as the liquid level becomes too low, a signal is triggered.

The suction lance extracts the medium via an integrated riser pipe. A built-in float switch monitors the liquid level in the container. If the level falls below a defined point, the reed contact switches and reports "container empty" or "refill required" to the control system or pump.

The suction lance consists of:

• Lance: Inserted into the container, reaches the bottom, and is used to extract the liquid.

• Connection piece: For hose connection to the dosing pump or similar.

• Level sensor: Usually integrated in the lower area of the lance.

• Non-return valve (optional): Prevents backflow.

The following factors are important for the design: medium, tank type, tank opening, immersion depth, desired switching point, connection type, electrical interface, temperature range, flow rate, and planned quantity.

Suction lances enable the easy removal of liquids from dosing containers or canisters with simultaneous container empty detection. They are also sometimes referred to as suction fittings.

A suction lance combines media extraction and level detection in a single component. This reduces installation effort, additional openings in the container, and potential leak points. It also simplifies integration into existing plants and control systems.

Binsack Reedtechnik suction lances are suitable for many liquid media, including:

• Chemicals and additives

• Cleaning agents and disinfectants

• Water and process fluids

• cooling lubricants

The choice of material (e.g., PP or PE) depends on the medium and its chemical properties.

Suction lances are suitable for:

• canister

• barrels

• IBC container

Length, mounting, and connections are adapted to the respective container geometry so that safe removal is possible down to a low fill level.

Yes, retrofitting is possible in many cases. To do so, the tank opening, immersion depth, mounting, hose connection, electrical interface, and medium must be checked.

The fill level is detected via potential-free reed switch contacts. These can be connected directly to pumps, relays, or industrial control systems (e.g., PLCs). This makes integration simple and reliable.

Optionally with integrated hose or hose connection plug or screw connection for your hoses.

Yes. Our suction lances are often customized. Adjustments are possible for, among other things:

• Total length of the suction lance

• Switching point(s) of the float switch

• Hose and threaded connections

• Additional components such as filters or check valves

1. Inquiry & key data - You tell us the medium, container type, temperature range, desired withdrawal quantity, switching points and quantities.

2. Technical coordination - we clarify mechanical and electrical interfaces directly with your development team.

3. Samples & testing - You will receive samples and technical documentation for testing in your system.

4. Release & series - after successful testing, we deliver in series in accordance with the framework agreement or call-off planning.

In this way, we ensure that the suction lance, container and system work together optimally - both technically and logistically.

Yes. Development and manufacturing take place in Germany. This guarantees consistent quality, short coordination channels, and high delivery reliability.

A suction lance (suction assembly) is used to safely and accurately pump liquids out of canisters, drums, or IBC containers. As the link to the metering pump, it ensures that chemicals are transferred cleanly and accurately.
