Agilent Scroll Pumps

Agilent Scroll Pumps for Clean, Dry Vacuum

When contamination is not an option, Agilent IDP scroll pumps are the answer. These are dry, oil-free vacuum pumps, which means they deliver roughing and backing vacuum without ever feeding oil vapor back into your system. For anyone running a mass spectrometer, backing a turbo pump, or working in an application where hydrocarbons would ruin the result, that clean operation is exactly what the job calls for.

Provac stocks new and rebuilt Agilent IDP scroll pumps across the range, and we carry the tip-seal kits and offer the repair service that keep these pumps running for the long haul. Whether you need a small pump for a single instrument or a larger one to back a turbo, we can help you pick the right model and keep it healthy.

How a Scroll Pump Works

The heart of a scroll pump is a pair of interleaved spiral scrolls, one fixed and one orbiting. As the moving scroll orbits, it traps pockets of gas at the outer edge and steadily compresses them inward toward the center, where the gas is exhausted. There are no vanes, no oil, and no sliding metal-on-metal contact in the gas path, which is what makes the pump both clean and quiet.

The only routine wear item is the tip seal, a strip that rides along the scroll to maintain the seal between pockets. When the tip seal eventually wears, you simply replace it, and the pump is back to full performance. That predictable, low-cost maintenance is a big part of why IDP pumps are so popular in labs that cannot tolerate downtime or contamination.

The IDP Range

Agilent builds the IDP line in several sizes, so you can match pumping speed to your chamber and your throughput. Provac stocks the full lineup:

•    IDP-3 for compact, quiet pumping of small instruments and backing small turbo pumps

•    IDP-7 as a versatile mid-range choice for roughing and backing

•    IDP-10 for higher throughput and larger chambers

•    IDP-15 for the maximum capacity in the dry scroll line

Where Scroll Pumps Are Used

Scroll pumps are a favorite wherever clean, oil-free vacuum is a requirement rather than a luxury. Common uses include:

•    Backing turbomolecular pumps in fully dry high vacuum systems

•    Mass spectrometry as well as gas and liquid chromatography

•    Load-lock and roughing duty in analytical tools

•    Research work that demands oil-free vacuum from start to finish

Clean Vacuum With Low Maintenance

One reason IDP scroll pumps have become a lab standard is how well they fit into a larger dry vacuum system. Pair a scroll pump with an Agilent turbo pump and you have a completely oil-free high vacuum stack, from atmosphere all the way down to your working pressure. The same pumps also back the Agilent diffusion pumps and pumping stations that Provac stocks, so a single family of dry pumps can support several different setups in your facility.

Maintenance stays simple. For most users, replacing the tip seal on schedule is the only regular service the pump needs, and we supply the kits to do it. That predictability makes budgeting and planning far easier than with pumps that need frequent oil changes and more involved upkeep.

New, Rebuilt, and Repaired at Provac

Buying from Provac gives you options that a single-source manufacturer often cannot. If a rebuilt pump fits your budget, we can supply one that has been cleaned, resealed, and tested. If you want new, we can source that. And if your current IDP pump just needs a rebuild, we can turn it around for you.

•    New and rebuilt IDP pumps ready to ship

•    Tip-seal kits and spare parts to keep pumps running

•    In-house repair and rebuild by experienced technicians

•    A warranty on rebuilt pumps so you are covered

How Often Do Tip Seals Need Replacing?

Tip-seal life depends on how hard the pump works and the environment it runs in, but replacement is a routine, predictable event rather than a surprise. A pump running long hours or handling heavier gas loads will wear its tip seal faster than one used lightly. The signs are easy to read. When ultimate pressure starts to slip or the pump takes longer to get there, a fresh tip seal usually restores full performance. Provac supplies the kits and can walk you through the replacement, or handle it for you as part of a service. Because this is the main wear item, budgeting for periodic tip-seal changes is really all the long-term planning an IDP pump requires.

Scroll Pumps Versus Oil-Sealed Pumps

If you are weighing a dry scroll pump against a traditional oil-sealed rotary vane pump, the deciding factor is usually cleanliness. Oil-sealed pumps can reach excellent pressures and often cost less up front, but they carry the risk of oil vapor migrating back toward your chamber, which is unacceptable in many analytical and semiconductor applications. Scroll pumps remove that risk entirely, along with the mess and disposal cost of used oil. For clean, dry, low-maintenance vacuum, the IDP line is hard to beat, and for many labs the freedom from oil is worth every bit of the investment.

Frequently Asked Questions

Which IDP model should I choose? It depends on your chamber size and whether you are roughing, backing a turbo, or both. Share the details and we will help you pick.

Do you sell tip-seal kits? Yes. We stock tip-seal kits and spare parts for the IDP line, and we can service the pump for you if you prefer.

Can a scroll pump back my turbo pump? Yes. A properly sized IDP scroll pump is an excellent, fully dry backing pump for Agilent turbo pumps.

Buying New Versus Rebuilt Scroll Pumps

A rebuilt IDP scroll pump is one of the best values in dry vacuum. When Provac rebuilds one of these pumps, we replace the tip seal, clean the scrolls, service the bearings and motor as needed, and test the pump against its rated performance before it ships with a warranty. For a great many labs, a rebuilt IDP performs indistinguishably from new for the roughing and backing work they do, and the money saved can go toward spare tip-seal kits or other equipment. If you need the latest model or want the longest possible service interval before the first rebuild, a new pump makes sense. We will walk you through the honest difference so the choice fits your budget and your workload rather than a sales target.

One Source for Dry Vacuum

Because the IDP line backs so many different systems, from turbo pumps to diffusion pumps to complete pumping stations, having one supplier who understands all of them is a real advantage. Provac sells, services, and rebuilds the whole family, and we stock the tip-seal kits and spare parts that keep them running. When a pump needs attention, you have one team to call rather than a scramble across several vendors, and that continuity keeps your dry vacuum dependable for the long term.

Why Buy Your Scroll Pump From Provac

Provac has spent decades working with dry pumps, and that experience helps you avoid the common mistakes, such as choosing a pump that is too small to back your turbo or too large for your instrument. We will help you match the pump to the job and support it afterward.
