Vacuum Pumps & Systems
A reliable vacuum supply sits behind filtration, evaporation, drying and degassing across almost every lab, and vacuum pumps provide it. Options run from oil free diaphragm units for clean rough vacuum to oil sealed and multistage systems that pull far deeper. Buyers weigh the ultimate vacuum, the pumping speed and whether an oil free or oil sealed design suits their process and upkeep. Listings here describe the vacuum rating and pump type so you can match a unit to your bench or process line. Reach the seller to confirm the pump meets your vacuum and cleanliness needs.

Vacuum Pump and System Types
Filed under liquid handling, pumps and fluid control, vacuum pumps and systems cover dry and oil sealed pumps and complete controlled setups. The variants differ by vacuum depth, cleanliness and the level of control.
Oil free diaphragm vacuum pumps
Dry pumps that pull a clean rough vacuum for filtration and aspiration. Their oil free head keeps the pumped gas free of contamination.
Oil sealed rotary vane pumps
Oil sealed pumps that reach a deeper vacuum for evaporation and freeze drying. They suit tasks where a dry pump cannot pull low enough.
Chemical duty vacuum systems
Corrosion resistant pumps with controllers that handle solvent vapours safely. Speed control and a condenser recover solvent and protect the pump.
Vacuum controllers and manifolds
Regulation and distribution units that set and split vacuum to several points. They give repeatable control across multiple bench positions.

Why Choose Machinery Masters
Verified Sellers Only
Every seller is verified before a single listing goes live. Machinery Masters also reviews listings for accuracy, so buyers can commit to high value machinery with confidence.
Global Reach
Listings come from sellers across Europe, North America, and beyond. That reach widens the options past any regional dealer network, and it is often the only way to find discontinued models in good condition.
Flexible Financing Options
Qualifying listings carry financing through partner providers. Terms are shown directly on eligible product pages, spreading the cost instead of draining working capital in one hit.
Direct Seller Contact
No broker sits between the buyer and the seller. Ask about service history, arrange inspections, and negotiate directly with the person who actually knows the machine.
Applications and Uses
These pumps power a broad set of separation and drying tasks across the lab. These are the common settings.
Vacuum filtration
Pulling liquid through membranes and filters for clarification and sterile filtration. A clean oil free pump protects the filtrate from contamination.
Rotary evaporation
Providing controlled vacuum to lower solvent boiling points during concentration. Speed controlled systems keep distillation steady.
Vacuum drying and desiccation
Removing moisture from samples and chambers under reduced pressure. The vacuum draws off water without high heat.
Degassing solvents and buffers
Removing dissolved gas from mobile phases before chromatography. Degassed fluids reduce bubble formation in detectors and pumps.
Benefits from Machinery Masters
The marketplace brings together vacuum equipment across the full range of lab duties.
The whole vacuum range in one category
Dry, oil sealed and chemical duty systems sit together for direct comparison, so you match vacuum depth and cleanliness to your process.
Refurbished vacuum pumps reach rated vacuum for less
A used vacuum pump performs to specification at a lower price than a new one, and the saving can cover a solvent trap, controller or service kit.
Vacuum and chemical fit confirmed by the seller
You confirm the ultimate vacuum and chemical resistance with the seller before buying, which ensures the pump suits your process and vapours.
Frequently Asked Questions About Vacuum Pumps & Systems
Oil free diaphragm pumps give a clean rough vacuum with little maintenance, which suits filtration and general bench work. Oil sealed pumps reach a much deeper vacuum for evaporation and freeze drying but need oil changes and can back stream vapour. Decide based on the vacuum depth you need and how clean the process must stay. The seller can confirm which type the listing is and how it was used.
Match both the ultimate vacuum and the pumping speed to the task, since filtration wants speed at rough vacuum while evaporation wants a lower ultimate pressure. A pump that pulls deep but slowly may frustrate a large filtration, and vice versa. Note the volume you process and the pressure you must reach. Give the seller those details so they can confirm the pump suits the duty.
A chemical duty pump with corrosion resistant internals, gas ballast and an inlet condenser handles solvent vapours safely. The condenser recovers solvent before it reaches the pump, and speed control limits the load. Without these, vapour condenses and corrodes the internals. Describe your vapours to the seller so they can confirm the system is suited and whether a trap is included.
For oil sealed pumps, regular oil changes and correct use of the gas ballast are the main upkeep tasks. Dry pumps need less attention but benefit from a clean inlet free of liquids and particles. Ask the seller about the service history, the state of the diaphragms or vanes and whether service kits are available. Good maintenance keeps the pump reaching its rated vacuum.
You contact the seller directly and can request a vacuum reading, photos and a video of the pump running. Because there is no middleman, arranging an inspection or demonstration is straightforward. Sellers here are vetted, which gives the vacuum pump exchange added confidence. Agree the terms of any test before you complete the purchase.
