Suction lances with float switches for canisters, drums, and IBCs

Binsack develops and manufactures suction lances with integrated empty-level 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. We generally evaluate custom suction lances for orders of 10 units or more.

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, the medium, immersion depth, desired residual quantity, media connection, switching points, and the electrical interface. Binsack first determines which existing product platform is suitable and which features need to be adapted for your production application.

Technical Options:
- 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 product platform 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 review
- custom series production projects, typically starting at 10 units

Select an existing product platform, configure it, or customize it as an OEM solution

Not every application requires a new development. We first assess whether an existing suction lance platform can be used as-is or adapted cost-effectively to the tank, medium, and interfaces.

1. Select an existing design

For typical container handling and retrieval tasks, we select a suitable platform from our existing product line.
Suitable for:

2. Configure the product platform

Length, switching points, tank connection, media connection, cables, and connectors are customized to your application within the capabilities of the product platform.
Suitable for:
3. Develop a Custom OEM Solution

If an existing platform is not sufficient, we develop a project-specific production model based on our components and manufacturing capabilities.

Suitable when:

These features can be customized

AreaPossible versions
Overall Depth and Immersion DepthFixed or adjustable length, up to 2,000 mm depending on the product platform
Tank ConnectionClamping technology, plug-in assembly, DIN 51, DIN 61, or DIN 71 canister lids, custom mounts
MaterialPP or PE, depending on the medium and design
Media ConnectionHose connector, hose fitting, integrated suction line
Number of linesOne through four suction or return lines
Level MonitoringEmpty signal, pre-empty and empty signals, or multiple defined switching points
Electrical DesignSwitching function and permissible electrical load depend on the product platform and input circuit
Electrical ConnectionLoose cable, custom cable length, M8, M12, or other connectors
Anti-theft protectionFilter or coarse screen
Backflow PreventionCan be integrated depending on the model
LabelingCustom product labeling and pin assignments are available
DocumentationTechnical drawings, inspection criteria, and project-specific documentation as agreed upon
Material Selection for the Medium in Use

The chemical resistance of a suction lance cannot be determined solely from the general designation “PP” or “PE.” For a reliable technical evaluation, we need at least:

Based on this information, we determine which product platform and material variant is suitable for the application.
Switching Points and Electrical Interface

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.

For the design, we specifically need:

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.

Why choose Binsack Reedtechnik for suction lances?

Customizable Product Platforms
We first assess whether an existing suction lance can be used or economically modified. This limits the development effort to only the changes that are actually necessary.

Development and Manufacturing in Mühlheim am Main
Design, plastic processing, cable assembly, machining, assembly, and testing are closely coordinated.

Samples prior to series production approval
If necessary, samples or prototypes can be used to verify installation space, assembly, switching points, media connections, and electrical interfaces.

Reproducible Series Production
Following technical approval, the agreed-upon product specifications are defined for repeatable production.

Experience with Reed Sensors
Binsack has been developing and manufacturing sensor solutions in Mühlheim am Main since 1993. More than 17.9 million sensors are in use worldwide.

Series production projects starting at manageable quantities
Custom suction lances are generally tested for series production projects starting at 10 units. The actual minimum order quantity depends on the costs associated with customization, tooling, and testing.

Here's How Your Application Becomes a Production Solution

1. Enter Key Data
You provide tank data, medium, temperature, installation conditions, media connections, setpoints, electrical interface, and planned quantities.

2. Select Product Platform
We determine which existing suction lance is technically and economically the most suitable.

3. Specify the design
Dimensions, materials, connections, media routing, setpoints, as well as cables and connectors are defined on a project-specific basis.

4. Prototype and approval
If necessary, the design is tested in a real-world system and subsequently technically approved.

5. Series production
The approved suction lance is manufactured in accordance with the agreed-upon technical specifications and delivery schedule.

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.
