Dry Pumps

We maintain one of the largest inventories of new and rebuilt ready-to-ship vacuum pumps in the United States, including dry vacuum pumps for industrial, scientific, semiconductor, pharmaceutical, and contamination-sensitive applications.

Dry pumps operate without sealing or lubricating fluids in the pumping chamber. This helps reduce the risk of oil entering the vacuum system or process. Our inventory includes dry screw pumps, dry claw pumps, scroll pumps, dry vane pumps, and multi-stage dry process pumps from established vacuum equipment manufacturers.

We offer new, rebuilt, and refurbished equipment, with availability, specifications, pricing, and warranty coverage varying by model. We can also evaluate, repair, or rebuild many existing dry pumps through our vacuum pump repair service.

Shop Dry Pumps by Manufacturer

Different manufacturers offer dry pump technologies designed for specific pressure ranges, gas loads, process conditions, and installation requirements. Choosing the correct manufacturer and model depends on the equipment already installed in your facility and the demands of your application.

Send us the following information to help us identify or source the correct equipment:

• Manufacturer

• Model number

• Equipment serial number, when available

• Required pumping speed

• Required ultimate pressure

• Inlet and exhaust connection sizes

• Voltage, phase, and frequency

• Application or process details

• Gas or vapor exposure

• Preferred condition, such as new or rebuilt

• Photos of the equipment nameplate and connections

We can review your requirements, check our available inventory, discuss suitable alternatives, or determine whether your existing pump can be repaired.

New vs. Rebuilt Dry Pumps: Which Is Right for You?

We offer both new and rebuilt dry pumps so you can choose equipment that fits your application, schedule, system configuration, and budget.

A new dry pump may be the better choice when you need:

• A current-production model

• A specific factory configuration

• Equipment for a newly designed vacuum system

• A particular motor, voltage, inlet, exhaust, or control setup

• A model that is not available in rebuilt condition

• New equipment that meets a project or facility purchasing requirement

A rebuilt dry pump may be appropriate when you need:

• Direct replacement for an existing model

• A compatible pump for an older vacuum system

• A discontinued model that remains important to your process

• Lower-cost alternative to available new equipment

• An unit that can be shipped sooner than a factory order

• Equipment restored and evaluated for continued service

The right choice depends on the individual pump. Confirm the condition, the included components, specifications, warranty terms, and expected availability before placing an order.

Our team can help you compare a new pump with available rebuilt options when you request a quote.

How to Choose the Right Dry Pump

A dry pump should be selected according to the complete vacuum system and process, not only by manufacturer or physical size. A pump with the wrong pumping speed, pressure capability, connection, or gas compatibility may not deliver the required performance.

Dry pump technology also matters. Provac’s current dry pump inventory includes several operating designs:

• Dry screw pumps use two intermeshing screws to compress and move gas through the pump.

• Dry claw pumps use claw-shaped rotors that rotate without contacting one another or the pump housing.

• Scroll pumps use fixed and orbiting spiral scrolls to create moving pockets of gas.

• Dry vane pumps use vanes mounted in a rotor to create compression.

• Multi-stage dry process pumps use multiple pumping stages to move gas through the system.

Each design offers different pumping speeds, pressure capabilities, maintenance requirements, noise levels, and process tolerances.

Key Specifications to Consider

Review the following specifications before selecting a dry pump:

• Pumping speed or flow rate: Choose a pump with enough capacity for the system volume, required evacuation time, and expected gas load.

• Ultimate pressure: Confirm that the pump can reach the lowest pressure required by the process.

• Inlet size and connection: Match the pump inlet to the chamber, piping, fittings, or existing vacuum equipment.

• Exhaust connection: Confirm the size and arrangement needed for safe discharge or connection to an exhaust system.

• Gas compatibility: Identify any corrosive, reactive, condensable, or particulate-heavy gases entering the pump.

• Motor requirements: Check voltage, phase, frequency, power, and control requirements.

• Cooling requirements: Determine whether the pump requires air cooling, water cooling, or another cooling configuration.

• Noise and vibration: Consider the installation environment, especially for laboratories and analytical equipment.

• Physical size and weight: Confirm that the pump fits the available installation area and can be properly supported.

• Controller and accessory requirements: Some pumps require specific controls, cables, filters, valves, or monitoring equipment.

• Equipment condition: Review whether the listed unit is new, rebuilt, refurbished, or available for quotation.

Individual Provac product pages may provide specifications such as pumping speed, ultimate pressure, inlet size, exhaust size, motor configuration, dimensions, weight, and available technical documents.

Additional manuals, sizing resources, contamination forms, warranty documents, and safety information are available in our documentation library.

Frequently Asked Questions About Dry Pumps

What is a dry pump?

A dry pump is a vacuum pump that operates without sealing or lubricating fluids in the pumping chamber. This design helps reduce the risk of oil entering the vacuum system or process.

Dry pump technologies include dry screw, dry claw, scroll, dry vane, and multi-stage dry process designs. The best type depends on the required pumping speed, ultimate pressure, gas compatibility, noise level, and application.

How long do rebuilt dry pumps last?

The service life of a rebuilt dry pump depends on the model, process conditions, operating schedule, gas exposure, contamination level, installation, and maintenance.

Regular inspections, performance monitoring, filter maintenance, proper cooling, and following the manufacturer’s service recommendations can help reduce preventable wear. Contact us when you notice changes in noise, vibration, leakage, temperature, or vacuum performance.

Do you offer a warranty?

Yes. Warranty coverage is available for qualifying products and repair services. The specific terms depend on the equipment, condition, quotation, and service performed.

Contact us to confirm the warranty provided with a particular dry pump. Warranty evaluations require communication with Provac and an RMA before equipment is returned.
