Pneumatic Units
Compressed air drives a surprising amount of lab and process automation, and pneumatic units are the components that put it to work. Air operated pumps, actuators and control assemblies move fluids, open valves and drive instruments without an electric motor in the fluid zone, which suits wet or flammable settings. Buyers look at the air supply the unit needs, its wetted materials and the duty it performs. Listings describe the air rating and function so you can match a unit to transfer, actuation or control duties. Speak to the seller to confirm the air supply and fit for your system.

Pneumatic Unit Types
Across the liquid handling, pumps and fluid control range, pneumatic units cover air driven pumps, actuators and control assemblies. The variants differ by whether they move fluid, drive motion or regulate air.
Air operated diaphragm pumps
Double diaphragm pumps run on compressed air that transfer fluids without an electric drive. They suit flammable and wet areas where a motor would be a hazard.
Pneumatic actuators and cylinders
Air driven pistons and rotary actuators that open valves and move mechanisms. They give reliable repeatable motion for automated lines.
Air control and regulation assemblies
Regulators, filters and solenoid valves that condition and switch the air supply. They protect downstream units and sequence pneumatic actions.
Pneumatic dosing and injection units
Air driven metering heads that deliver a set volume on each cycle. They dose additives into a process where electrical drives are unsuitable.

Porquê escolher a Machinery Masters
Apenas vendedores verificados
Cada vendedor é verificado antes de qualquer anúncio ser publicado. A Machinery Masters também revê a exatidão dos anúncios, para que os compradores possam investir com confiança em maquinaria de elevado valor.
Alcance global
Os anúncios provêm de vendedores de toda a Europa, da América do Norte e de outros locais. Esse alcance alarga as opções para além de qualquer rede regional de revendedores e é muitas vezes a única forma de encontrar modelos descontinuados em bom estado.
Opções de financiamento flexíveis
Os anúncios elegíveis dispõem de financiamento através de parceiros. As condições são apresentadas diretamente nas páginas de produto elegíveis, repartindo o custo em vez de esgotar o fundo de maneio de uma só vez.
Contacto direto com o vendedor
Não há nenhum intermediário entre o comprador e o vendedor. Pergunte pelo histórico de manutenção, combine inspeções e negocie diretamente com a pessoa que realmente conhece a máquina.
Applications and Uses
Pneumatic units handle fluid movement and motion where compressed air is the sensible power source. These are the common settings.
Fluid transfer in hazardous areas
Moving solvents and flammable liquids where an electric motor poses an ignition risk. Air driven pumps run safely in these zones.
Valve and gate actuation
Opening and closing process valves under automated control. Pneumatic actuators deliver quick repeatable movement on the line.
Air supply conditioning
Filtering, regulating and switching plant air before it reaches instruments. Control assemblies keep the supply clean and at the right pressure.
Additive dosing
Injecting set volumes of additive into a process stream on each cycle. Air driven metering suits wet and classified areas.
Benefits from Machinery Masters
The marketplace gathers air driven pumps, actuators and controls so you can build a pneumatic circuit from one place.
01
Air powered kit for wet and classified zones
The category brings together pneumatic units built to run on compressed air rather than electricity, which suits setups where an electric drive is unsuitable.
02
Reconditioned pneumatic units lower outlay
A used pneumatic unit such as an air operated pump or actuator performs reliably for less than a new one, freeing budget for fittings and filters.
03
Air rating and fit confirmed by the seller
You confirm the air pressure and flow a pneumatic unit needs before you buy, which ensures your compressed air supply can drive it.
Frequently Asked Questions sobre Pneumatic Units
Each pneumatic unit states the air pressure and flow it needs to run at its rated duty, and your supply must meet both. An air operated pump in particular draws significant air volume when working hard. Check your compressor capacity and line pressure against the unit's requirement. Ask the seller for the air consumption figures so you can confirm your supply is adequate.
Air operated pumps carry no electric motor in the fluid zone, which makes them safer in flammable, wet or classified areas. They also stall harmlessly against a closed line and run dry without damage. Where an ignition source is a concern, this is a decisive advantage. If your area has no such constraint, an electric pump may be simpler, so weigh the duty against your site conditions.
Clean dry air is the single biggest factor, so a good filter and water trap on the supply protects the internals. Moisture and particles cause valves to stick and diaphragms to wear early. Ask the seller about the condition of the wetted and air side parts and whether service kits exist. Regular attention to the air supply keeps these units dependable.
Yes, solenoid valves switch the air to actuators under signals from a controller, which is how automated lines sequence motion. Check that the actuator's port sizes and stroke suit your valve or mechanism. Confirm with the seller whether the unit comes with its solenoid and any position feedback. Matching these lets the actuator drop into your control scheme.
Sellers on the marketplace are verified, and a listing should say whether the unit was tested on air before sale. You can ask the seller directly for a functional check and photos of the ports and seals. Because you deal with the seller with no middleman, that request is quick to arrange. Agree any inspection you want before you buy.
