Flux Pumps Compression Gland

• Compatible with drum, barrel and IBC pumps

• F 300 models fit 40 – 70 mm container openings
• F 400 model fits containers with 2-inch BSP female opening
• Alternative compression glands are available for Flux 400 and F 500 series pumps eg. to suit polyethylene drums with buttress threads. Please contact us for details.

A compression gland is a precision-engineered adaptor, designed to secure a cylindrical object, typically a drum pump shaft or suction tube, in a container opening, such as a drum or IBC.

The compression gland functions by applying radial compression through mechanical tightening. This action forces a sealing element (often made from elastomeric or thermoplastic material) to conform around the inserted tube.

Furthermore, the gland secures the pump in the container, eliminating unwanted movement that could cause the container to become unstable, particularly when nearly empty.
When installed, the gland retains an open slot to allow air in and out of the container, therefore stopping a vacuum forming.

Additionally, the gland also creates a barrier that reduces the potential of atmospheric contaminants (dust, debris, moisture or microbes) from entering the container, while simultaneously minimising the emission of vapours, or hazardous fumes, into the work environment.

Special applications and compression glands

This is particularly important when working with volatile organic compounds, reactive chemicals, or food products, helping to ensure process integrity, operator protection and compliance with environmental and health regulations such as REACH, FDA, or EC 1935/2004 standards, depending on the application.

Compression glands with alternative threads are available for F 300, F 400 and F 500 series Flux pumps. Contact us for further details.

Flux offers two solutions to securely fix a pump into a drum or IBC container. A compression gland is a cost-effective, dual-function solution: it stabilises the pump tube during operation and creates a partial seal that isolates the container’s contents from external contamination sources.

The second option is the fume gland – this totally seals the pump into the container, thereby eliminating the risk of harmful vapour emissions. You can find out more about fume glands here.

The compression gland is simple to use. Simply slide the gland over the end of the pump tube, or suction lance. Then insert the pump into the container to be emptied. Push the gland down into the container opening.

In doing so, pressure is applied uniformly around the pump tube until the pump is secured.  This prevents unwanted movement or tilting during fluid transfer but also creates a partial seal around the tube.

Reducing vapour emissions

This is especially important when dealing with hazardous, flammable, or hygroscopic substances, where exposure to air can degrade the product, or pose safety risks. The compression gland also serves to reduce vapour emissions, reducing operator exposure as recommended by Health and Safety guidelines.
