Diaphragm pumps

VACUUBRAND diaphragm pumps for laboratories

Modern VACUUBRAND devices are an efficient solution for laboratories. Thanks to their compact design, they work perfectly with analytical equipment and OEM systems. At their heart is oil-free technology, based on chemically resistant FKM membranes. This guarantees a clean vacuum – compliant with stringent FDA standards – which is crucial in the food and pharmaceutical sectors.

The advantages of VACUUBRAND diaphragm pumps for laboratories are:

• precise adjustment of operating parameters,
• achieving a final vacuum of 0.3 mbar,
• effective support for filtration and drying processes,
• full repeatability of tests - thanks to controllers,
• Intuitive servicing and quick parts replacement.

Stable and quiet operation is combined with measurable operational savings. Robust components allow you to maintain the full power of the engine for many years. The industry values these devices primarily for their versatility. Additional protection is provided by separators, which, in combination with automation, guarantee full control over every step of the laboratory process.

Oil-free vacuum technology for diaphragm pumps

The operation of the diaphragm pumps of the devices is based on the precise movement of the diaphragm inside a hermetic chamber. This design ensures full separation of the pressed medium, which is crucial for maintaining the cleanliness of laboratory and industrial processes. The use of modern materials makes these pumps irreplaceable when working with demanding media.

The advantages of these devices are:

• complete gas isolation, eliminating the risk of oil contamination of samples,
• the possibility of safe pumping of aggressive fumes and corrosive substances,
• maintaining the highest standards of sterility throughout the entire work cycle,
• high efficiency during distillation and degassing processes,
• no need for lubricants, which generates significant service savings,
• reducing the accumulation of unwanted condensate inside the system,
• Complies with the stringent ATEX standard for potentially explosive

In high-risk environments, dual diaphragms ensure reliability. They provide an additional protective barrier, ensuring absolute tightness and safety of personnel even in the most demanding operating conditions. Thanks to this, industrial processes run smoothly, while maintaining full control over the operating parameters.

One-, two-, three- and four-stage models

The performance of the device depends primarily on the number of compression stages. While simple tasks are accomplished by single-stage models, demanding processes need multi-step versions. This design allows for a deeper vacuum and a stable gas flow. The precision of operation results directly from the technical parameters – advanced systems reach a ceiling of 1.5 mbar or even 0.3 mbar.

The use of modern mechanisms translates into specific utility advantages, such as:

• effective noise reduction and vibration damping,
• high tightness - thanks to non-return valves,
• exceptional wear resistance of components,
• minimizing service needs,
• stability of work in various conditions,
• precise control of the flow of the medium.

The choice of solution depends on the environment. Laboratories prefer electric pumps with eccentric drives, industry relies on pneumatic models, and in the field, high-power diesel versions, operating independently of infrastructure, are irreplaceable.

Vacuum ranges from 70 mbar to 0.6 mbar

These devices are characterized by stable operation in a wide range of pressures - from 70 to only 0.6 mbar. With a throughput of up to 18.4 m3/h and excellent self-priming capabilities, they provide reliable support in rigorous analytical tests where the precision of every parameter counts. The refined design guarantees high work culture and extremely low noise levels.

The use of digital control not only protects the system from overload, but also significantly extends service intervals, which directly translates into the durability and reliability of the equipment.

In everyday laboratory practice, these pumps offer users measurable benefits:

• stable operation in the range from 70 to 0.6 mbar,
• high efficiency at the level of 18.4 m3/h,
• effective protection against vapours and condensate,
• precise evaporation of solvents and filtration,
• full reproducibility of tests thanks to intelligent automation.

Quiet operation and long diaphragm life

VACUUBRAND devices set standards for above-average service life and reliability in harsh testing environments. The use of innovative materials ensures that the membranes remain fully functional regardless of the type of pressed medium, and the advanced design ensures a unique work culture. Thanks to precise pneumatic systems and pulsation dampers, vibrations are almost completely eliminated, which directly translates into silence in the laboratory.

The highest quality components are used in the production process, which guarantee resistance to demanding environments:

• modern PTFE and EPDM elastomers,
• corrosion-resistant AISI 316 steel,
• durable cast iron castings,
• lightweight and durable aluminum,
• additional polyethylene reinforcements.

The hermetic design of the devices guarantees full stability of parameters, which is crucial for the repeatability of technological processes. Each component is designed to effectively protect the mechanisms from premature wear, offering users maximum safety and efficiency even in the most aggressive chemical and industrial environments.

Pumps for chemical laboratories and industry

The demanding environment of the chemical industry necessitates the use of reliable equipment for the transfer of dense and corrosive substances. Thanks to their free-passage design, these devices deal with sludge by reducing wear on the mechanisms.

The key advantages of modern systems are:

• Effective high-density media stamping
• high resistance to aggressive chemicals,
• safe operation in ATEX zones,
• precise dosing of reagents,
• complete elimination of the risk of leakage,
• Optimum performance thanks to matching drive power.

In wastewater treatment plants, the safety of toxin transport is crucial. Submersible pumps operating in submersible operation guarantee tightness and durability. Remember that the right selection of technical parameters ensures maximum work efficiency.

Accessories – Separators, Capacitors & Vacuum Control

The right selection of accessories is the foundation for full optimization of industrial and laboratory processes. The use of modern technologies allows for precise control of parameters and significant improvement of occupational health and safety.

Key elements of a modern system include:

• intelligent VACUU-SELECT controllers, correcting vacuum parameters,
• dedicated separators, protecting the mechanisms against liquid suction,
• emission capacitors, enabling almost 100% recovery of solvents,
• pneumatic systems, perfectly cooperating with filter presses,
• powder pumps, eliminating annoying dust during the transport of raw materials,
• precise DN6/10 mm stubs, guaranteeing full tightness and repeatability.

The implementation of these solutions in industrial painting brings measurable economic and ecological benefits. By investing in advanced automation, you can reduce your uptime by 20% while increasing productivity by 30% compared to manual methods. Thanks to this, each subsequent production cycle becomes fully repeatable and safe for the natural environment.
