Agilent Turbo Pump Controllers

Agilent Turbo Pump Controllers That Drive and Protect Your Pump

A turbomolecular pump cannot run on its own. It needs a controller, and the controller is far more than a simple power supply. It is the electronic brain that spins the rotor up to speed, holds it there, watches over temperature and current, and shuts everything down safely the moment something goes wrong. Get the controller right and your turbo pump runs reliably for years. Get it wrong and you risk expensive rotor damage.

Provac stocks new and rebuilt Agilent turbo pump controllers, including TwisTorr and Navigator series units. Every controller we sell is tested and warranty backed, so you can install it with confidence. If your existing controller has failed, we also offer repair, which is often far cheaper than replacement.

What a Controller Actually Does

It helps to understand just how much work the controller is doing while your pump spins. A turbo pump rotor turns at extremely high speed, and reaching that speed safely takes careful control of the drive frequency. The controller handles all of it, along with several protective jobs that keep the pump alive:

•    Spin-up and speed regulation, bringing the rotor to its rated rotational frequency and holding it there

•    Temperature and current monitoring, with automatic fault protection if either climbs too high

•    Vent and purge control, so the pump comes to rest safely when it stops

•    Status and communication outputs that let the pump report into a larger system

Without these functions working together, a turbo pump would be both unreliable and unsafe. The controller is what turns a spinning rotor into a dependable vacuum tool.

Matching the Controller to Your Pump

The single most important thing to get right is compatibility. Every turbo pump needs a controller rated for its specific model and power requirements. Install a mismatched controller and, at best, the pump will not reach speed. At worst, you risk damage. This is where buying from a vacuum specialist pays off. Provac can help you pair a controller with the correct Agilent turbo pump, or supply the two together as a matched set. If you would rather have the whole system handled for you, an Agilent pumping station includes the pump and a matched controller already configured.

There is also a diagnostic angle worth knowing. If a turbo pump will not spin up or keeps faulting, the controller is one of the first things to check. Testing a known-good controller against the pump quickly tells you whether the problem lies in the controller or the pump itself, which can save hours of troubleshooting.

Repair and Exchange Options

Controllers are electronic devices, and like all electronics they can fail. When yours does, you have more than one path forward with Provac. We can supply a rebuilt controller that has been tested against a live pump, repair the board-level fault in your existing unit, or set you up with a replacement that is ready to run.

•    Rebuilt controllers tested against real pumps before they ship

•    Board-level repair of your existing controller

•    A warranty on rebuilt inventory

•    Help confirming compatibility before you buy

How to Identify the Right Controller

Finding the correct controller starts with your pump. The model and part number of your turbo pump determine which controllers are compatible, along with the power and communication options your system needs. If you are not sure what you have, we can help you identify the pump from its label or its physical features and then point you to the controllers that will drive it safely. This step is worth doing carefully, because a controller that is close but not quite right can leave a pump unable to reach speed or, worse, unprotected against a fault. A few minutes confirming compatibility up front saves a great deal of frustration later.

Signs Your Controller May Be Failing

Controllers usually give warning before they quit entirely. A pump that struggles to reach full speed, trips on faults without an obvious cause, or fails to start at all can point to a controller problem rather than a pump problem. Error codes and status lights, where the controller provides them, are useful clues. Because swapping in a known-good controller is a quick test, checking the controller is often the fastest way to narrow down a turbo pump issue. If the tested controller solves the problem, you have saved yourself an unnecessary and costly pump rebuild. If it does not, you have ruled out one major variable.

Frequently Asked Questions

How do I know which controller fits my pump? Give us your turbo pump model and we will confirm which controllers are compatible before you buy.

Can you repair my failed controller? Often, yes. We offer board-level repair as well as tested rebuilt units and ready-to-run replacements.

Is the controller included with a pumping station? Yes. A complete Agilent pumping station comes with a matched controller already configured for its pump.

Communication and Integration Options

Modern turbo pump controllers do more than spin a pump. Many offer communication interfaces that let the controller report pump speed, temperature, and fault status to a larger control system, and accept commands to start, stop, or adjust the pump remotely. If you are integrating a turbo pump into an automated tool or a larger instrument, these communication options can matter a great deal, since they determine how well the pump fits into your control scheme. When you are choosing a controller, it is worth telling us how you plan to use it, because the right interface can make integration smooth while the wrong one can turn it into a headache. We will help you pick a controller whose features line up with the system you are building.

New, Rebuilt, and Repaired Options

Provac gives you more than one way to solve a controller problem, which keeps both your downtime and your costs under control. A tested rebuilt controller can get you running quickly at a lower price than new. Board-level repair of your existing unit can be the most economical path when the fault is contained. And a new controller is there when you want the latest hardware. Whichever route fits your situation, the unit is tested and backed by a warranty on rebuilt inventory, so you can install it knowing it will protect your pump.

Why the Right Controller Protects Your Investment

It is easy to think of a controller as an accessory, but it is really the guardian of a very expensive pump. A turbo pump rotor spins fast enough that a fault caught a moment too late can turn a minor issue into a destroyed rotor. The controller is what watches temperature, current, and speed and steps in before that happens. Spending a little care to get the right, healthy controller in place is some of the cheapest insurance you can buy for a turbo pump. Provac helps you choose a controller matched to your pump and keeps it in good repair, so the protection is always there when your pump needs it.

Why Buy Your Controller From Provac

Controllers seem like a simple purchase until you install the wrong one. Provac's decades of vacuum experience mean we can steer you to the right unit the first time, whether you know your pump model off the top of your head or need help identifying it. That guidance alone can save you a costly mistake.

Because we work with the pumps and the stations these controllers drive, we see the whole picture rather than just one part.
