How The Latest Oil-Free Vacuum Pumps are Researchers’ Best Friends to Save Time & Money

What to Know about Oil-Free Vacuum Pumps and How They Became Game-Changers in Research & Industrial Applications

Intro: What is an Oil-Free Vacuum Pump and How Does it Actually Work?

Oil-free vacuum pumps are the disrupting counterpart of those classical oil-sealed rotary vane pumps.

Dry pumps are another name for them – but are they really dry?

Yes! Oil-free vacuum pumps operate without the use of oil as a sealing element.

The absence of oil or other hydrocarbons makes all the difference for research and industrial applications, as well as for the environment.

How does the scroll mechanism actually work?

Agilent IDP pumps, for example, create a vacuum with a simple dual-scroll mechanism in which one nested scroll rotates within the other, resulting in moving zones of collected gas. After entering the scroll perimeter, the gas is compressed and moved toward the center hub, where it is exhausted. This lets you achieve the desired “nothingness”.


Have a look at the Agilent Dry Scroll Pumps page to find out more.

By contrast, a vane pump uses a revolving cylinder (rotor) with slots that house a series of vanes rotating in the cavity where the rotor is lodged. Because the rotor is misaligned in the casing bore, the vanes slide in and out as the rotor rotates. As a result, volumes expand and contract, moving gases through the pump.

This is normally oil-sealed, which means that oil creates an effective seal between the vanes tip and the cavity internal surface and allows for a vacuum of up to 0,5 bar.

Why oil-free vacuum pumps are sensationally effective: maintenance-free and pollution-free.

The old-school oil-sealed rotary vane pumps have a number of drawbacks. To begin, the oil must be replaced and disposed of whenever it becomes discolored, which is usually every 6 to 12 months. Worse yet, the expense of disposing of used oil may be higher per liter than the full purchase price.

Oil starvation or clogged lubrication passageways are the most common causes of rotary vane pump failure, resulting in costly repair calls and hours of unplanned downtime.

Loud noise, oil leaks, and pump failures are major sources of annoyance, additional costs, and productivity loss.

How Oil-Free Vacuum Pumps Can Help You with 5 Amazing Features

1.   Superior performance than pumps of the same size

Isolated Dry Pumps (IDP) pump down quickly to low base pressures, maximizing turbo pump performance (when used as TMP foreline pumps) and ensuring overall vacuum system reliability and stability. Dry IDP scroll pumps are able to provide a powerful vacuum with high gas flow and quick pumping rates.

2. Cleaner environment inside your lab & greener outside

Oil-free IDP scroll pumps completely eliminate the risk of hydrocarbons spilling, leaking, or infiltrating the vacuum system. The absence of oil reduces their already modest carbon footprint: IDP scroll pumps decrease pollution in the air, water, and soil. Environmentally friendly from every angle.

Because scroll pumps do not use oil, they have a cheaper cost of ownership. Forget about costly oil topping, changing, and hazardous waste removal.

Agilent earned the 2018 Sustainability Leadership Award from the Business Intelligence Group for its commitment to sustainability through innovative product design.

3.   Less downtime – Service your pump in less than 15 minutes

Unlike traditional pumps, which require hours of scheduled maintenance, IDP scroll pumps just require a 15-minute seal element replacement with two basic tools. Even yet, this procedure can be performed infrequently, because Agilent solid tip-seals are designed to last up to three years.

See how simple it is to replace the tip seals:

4. Easy installation and integration – all around the world

IDP pumps fit into any system design thanks to their tiny footprint, lower weight, and low power requirements. They are easy on utilities and may be used even inside cabinet enclosures. The Agilent IDP-3 dry scroll pump, for example, is the smallest scroll pump for typical vacuum applications and weighs only 9.5 kg (21 lb).

IDP scroll pumps from Agilent also use regular IEC power cords that aren’t hard-wired to the motor, allowing operation anywhere around the world. A simple switch also allows you to switch between high and low-voltage operations.

5.  A more enjoyable workplace – vacuum pump that is easy on the ears

There is no hydrocarbon exhaust and no oil mist filter in the revolutionary scroll pump design.

Most importantly, even without a quiet cover, their low noise and minimum vibration make the workday more enjoyable for everyone in your lab. Agilent consulted noise experts while designing their IDP scroll pump module to ensure silent operation. Take a look at how the Agilent IDP scroll pumps stack up against common everyday noises.

Which Oil Free Vacuum Pump Fits Your Research Needs? New Application Possibilities

From nuclear fusion and space research to food packaging and analytical instruments, vacuum is required in a variety of applications. Discover here the most unexpected vacuum uses and how they work with Agilent pumps.

  • Isolated bearings in Agilent IDP hermetic dry scroll pumps provide a quiet, clean, and oil-free vacuum. They’re ideal for analytical instrumentation, cryogenics, helium recirculation, freeze dryers, cannabis extraction, and backing turbopumps, among many other purposes.
  • Freeze drying, glove boxes, sample preparation, scanning electron microscopes (SEM), and other applications also benefit from the introduction of IDP-3, IDP-10, and IDP-7 scroll pumps by Agilent – plus they are also great for supporting load-lock systems.
  • Leak detection, manufacturing operations, and other industrial applications all use TriScroll pumps. Agilent TriScroll pumps are distinguished by high pumping rates, low base pressures, and an optional inverter or three-phase motor.

Most importantly, our wide variety of pumping speeds makes it easy to customize any system setup for optimal performance at the lowest cost.
