Suction lances with float switches for canisters, drums, and IBCs
Binsack develops and manufactures suction lances with integrated empty-tank detection for dosing and conveying systems. The tank connection, immersion depth, media routing, switching points, and cables and connectors are designed to suit the specific application.
Suction Lances for Dosing and Conveying Systems
A suction lance connects the extraction of media from canisters, drums, tanks, or IBC containers to the feed line for the dosing or conveying system.
The key factors for technical selection include, above all, container geometry, media type, immersion depth, desired residual quantity, media connection, switching points, and electrical interface.
Binsack first determines which existing suction lance design is suitable and which features need to be adapted for your production application.
- Media withdrawal and level monitoring in a single assembly
- For canisters, drums, tanks, and IBC containers
- One or more defined switching points
- PP and PE versions depending on the suction lance design and medium
- variable lengths, container, hose, and electrical connections
- filters, backflow prevention, and multiple suction or return lines depending on the version
- samples and prototypes following technical testing
- custom series production projects, typically starting at 10 units

Select, customize, or develop new suction lances
Not every application requires a new design.
We first check whether a suction lance from our existing product line already meets your requirements or can be optimally tailored to your application through modifications to the tank, fluid, and connections.
2. Configure the suction lance
Length, switch points, tank connection, media connection, cable, and plug are customized for your application.
Suitable when:
If an existing suction lance is not sufficient, we develop a project-specific production model based on our components and manufacturing capabilities.
Suitable when:
These features can be customized
| Area | Possible versions |
|---|---|
| Overall Depth and Immersion Depth | Fixed or adjustable length, depending on the suction lance, up to 2,000 mm |
| Tank Connection | Clamping technology, plug-in assembly, DIN 51, DIN 61, or DIN 71 canister lids, custom mounts |
| Material | PP or PE, depending on the medium and design |
| Media Connection | Hose connector, hose fitting, integrated suction line |
| Number of lines | One through four suction or return lines |
| Level Monitoring | Empty signal, pre-empty and empty signals, or multiple defined switching points |
| Electrical Design | Switching function and permissible electrical load depend on the suction lance and the input circuit |
| Electrical Connection | Loose cable, custom cable length, M8, M12, or other connectors |
| Anti-theft protection | Filter or coarse screen |
| Backflow Prevention | Can be integrated depending on the model |
| Labeling | Custom product labeling and pin assignments are available |
| Documentation | Technical drawings, inspection criteria, and project-specific documentation as agreed upon |
Based on this information, we determine which suction lance and material configuration is suitable for the application.
Level monitoring is designed to be compatible with the intended control system. The number and position of the switching points, as well as the application’s electrical interface, are critical factors.
Typical Applications and Industries
Cleaning and Hygiene Technology
Media dispensing from canisters and drums with level detection for container changes or system control.
Water and Environmental Technology
Media supply to dosing and treatment systems.
Machine and Equipment Manufacturing
Supply of operating or process media to machines and equipment.
Dosing and Conveying Technology
Connection between storage tank and pump, optionally with multiple switching points as well as multiple suction or return lines.
Why combine a suction lance and a level switch?
An integrated suction lance reduces the number of separate components in the tank. Media withdrawal and level monitoring are combined into a single assembly.

Example Application:
Suction lance for dispensing chemicals, cleaners, and process media
A metering suction lance connects the fluid intake from storage tanks to the feed line for the metering pump. Depending on the application, float switches, filters, backflow preventers, lid adapters, and custom connections can be integrated.
As the liquid level drops, the float moves along the suction tube and activates the reed switch. The switching signal can be used by the connected control system for the following functions, for example:
Combining multiple functions into a single assembly saves space and can reduce assembly time.

Frequently asked questions about our suction lances
What is a suction lance?
A suction lance extracts liquids from canisters, drums, tanks, or IBC containers and feeds them into a dosing or conveying system. Depending on the model, level monitoring, filters, or backflow prevention can also be integrated.
What is the advantage of a suction lance with a float switch?
Media extraction and level monitoring are combined in a single assembly. At a defined fill level, the float switch generates a signal for a warning, a low-level indicator, or an appropriate system control.
Can pre-empty and empty notifications be combined?
Yes. Depending on the product platform, two or more defined switching points can be integrated.
Is it possible to have multiple suction or return lines?
Yes. The SL1212 product platform can be configured with up to four independent suction or return lines.
Which suction lance ensures a particularly low residual volume?
The SL1214 has a low switching point of approximately 17 mm above the bottom of the tank. The remaining quantity also depends on the tank geometry and installation configuration.
Which model is suitable for small container openings?
The SL1065 has an outer diameter of 22 mm and is designed for small container openings and tight installation spaces.
What materials are available?
Depending on the product platform, PP or PE versions are available. Suitability is determined based on the specific medium and operating conditions.
Which features can be customized?
Depending on the product platform, various features can be customized, including length, tank connection, media connection, switching points, cables, connectors, filters, and backflow prevention.
What is the minimum order quantity, and are samples available?
