Rebuild and Repair FAQ

What brands of vacuum pumps and blowers does GLV service?

We regularly service GLV, Stokes, Edwards, Microvac, Leybold, Kinney, Roots, Tuthill, and Welch equipment. Common models we rebuild include:

• GLV 1.5 and GLV 3.0 pumps
• Edwards Stokes 212H, 212J, 412H, 412J, and 612MB Microvac rotary piston pumps
• Leybold TRIVAC D65 B and SOGEVAC SV 300 B vacuum pumps
• Leybold RUVAC WAU 1001 and WSU 1001 mechanical booster pumps
• Welch DuoSeal 1376 vacuum pumps
• Roots 10×24 RGS HVB mechanical booster blowers
• Edwards Stokes 615 Microvac boosters

If your pump isn't on this list, contact us anyway — we have relationships with most major industrial vacuum equipment OEMs and can source parts or handle unusual rebuilds.

What's included in a standard vacuum pump rebuild at GLV?

Every standard rebuild at GLV follows the same Statement of Work:

• Receiving inspection with photos of any shipping damage or unusual wear.
• Complete teardown — every nut and bolt removed, damaged parts and failure debris documented photographically.
• Caustic hot tank cleaning, industrial parts washer cycle, rinse and air dry (aluminum and delicate parts handled separately).
• Detailed inspection of every wear surface with calipers and micrometers, compared to OEM specifications.
• Written quote showing anything required beyond the standard rebuild before we proceed.
• Replacement of all gaskets, O-rings, lip seals, mechanical seals, shaft sleeves, sight glasses, pump and motor bearings, vee belts, clappers, poppets, springs, freeze plugs, solenoid valves, check valves, ball valves, and oil flow indicators.
• Motor-to-solenoid wiring redone in seal-tight where applicable.
• Pre-lube, fresh oil fill, helium leak check, and a four-hour vacuum level performance test monitoring temperature, vacuum level, and motor amperage.
• Repaint in our paint booth with high-quality paint, multiple coats. New warning labels, operation labels, and updated serial tag.
• Custom heavy-duty skid sized to the unit, bagged and wrapped, bolted down with side protection for shipping.

The goal is that the rebuilt equipment is indistinguishable from new in both appearance and performance.

How long does a vacuum pump rebuild take?

Standard rebuild turnaround is typically 4–8 weeks from receipt of the pump, depending on current shop load, parts availability, and whether the teardown inspection reveals issues beyond a standard rebuild. For rush situations, call us directly at (888) 633-7127 — we can sometimes accommodate expedited timelines on common pump families where we stock subassemblies.

How much does it cost to rebuild a vacuum pump?

Rebuild pricing depends heavily on pump family, pump size, and condition at teardown. After the initial inspection we provide a written quote showing the standard rebuild cost plus any parts or labor required beyond a standard rebuild (for example, hot pumps, oxygen service pumps, electric motor repairs beyond bearings, or pump-and-blower packages).

A rebuilt pump typically costs a fraction of a new replacement while delivering the same performance and a longer warranty than most used equipment. For a ballpark before you ship, call (888) 633-7127 or email a contact form with your pump make, model, serial number, and a photo of the nameplate.

What's the difference between repair, rebuild, and remanufacture?

In our shop, these terms mean different things:

• Repair — fixing a specific failure, such as replacing a failed seal or bearing, without a full teardown.
• Rebuild — complete teardown, cleaning, inspection, and replacement of all standard wear parts to restore the pump to OEM specifications. This is what most customers mean when they ask for a “rebuild.”
• Remanufacture — the full rebuild process applied to a pump that we own and sell, resulting in equipment indistinguishable from new. Remanufactured pumps ship with a longer warranty (18 months on Stokes) and are tested, painted, and labeled as new stock.

What warranty does GLV offer on rebuilt and remanufactured pumps?

Warranty terms by equipment type:

• Stokes rebuilds and remanufactured Stokes pumps: 18 months from date of shipment or rebuild.
• Other brand rebuilds (Edwards, Leybold, Kinney, Welch, Roots, Tuthill, etc.): mostly 18 months but varies based on rotary piston, vanes, and blowers.
• New GLV pumps (GLV 1.5, GLV 3.0): 25 months from date of shipment.

All warranties cover defects in material and workmanship provided the equipment is used according to the instructions and preventive maintenance requirements in the OEM manual. Shipping costs are not covered under warranty.

Are rebuilt vacuum pumps as good as new?

For the pump families we specialize in — particularly Stokes Microvac rotary piston pumps — a properly rebuilt pump performs identically to a new one. Our rebuild process replaces every standard wear item with OEM-spec parts, restores machined surfaces, helium leak checks the assembled pump, and runs a four-hour vacuum level performance test. Any part out of OEM tolerance is replaced; we do not use repaired or non-OEM-size parts. Many of our remanufactured pumps ship with an 18-month warranty — longer than the warranty on most used equipment.

Do you service pumps in oxygen or hot-process service?

Yes. Hot pumps, oxygen service pumps, and pump-and-blower packages require additional parts and labor beyond a standard rebuild. These are quoted separately after teardown inspection. If you're shipping a pump from oxygen service, please note that on your paperwork so we handle it with the appropriate cleaning protocols.

Can GLV repair electric motors on vacuum pumps?

We handle motor bearing replacement as part of a standard rebuild. Electric motor repairs beyond bearings (rewinds, stator replacement, etc.) are considered additional and are quoted separately for customer approval. In many cases we coordinate with a motor shop partner to handle those repairs before pump reassembly.

How do I know if my vacuum pump needs a rebuild vs. a minor repair?

Common signs that a pump needs more than a minor repair include: inability to reach or hold ultimate vacuum, oil contamination or excessive oil carryover at the exhaust, unusual noise or vibration, elevated operating temperature, or visible oil leaks at seals. Read our full diagnostic guide.

Shipping, Pickup, and Logistics

Does GLV ship worldwide?

Yes. We ship parts, kits, oils, and full pump assemblies worldwide. For rebuilt or remanufactured pumps, units are custom-skidded, bagged, wrapped, and fastened to a heavy-duty skid sized specifically to the unit. For international shipments, contact us in advance so we can prepare the appropriate export documentation and quote freight.

How do I ship my vacuum pump to GLV for repair?

Drain the oil before shipping, note any known issues on your paperwork, and include your contact information and return shipping preferences. Common carrier shipping to our Comstock Park facility is the standard route. Local customers in West Michigan can arrange drop-off or pickup. For help coordinating freight, call (888) 633-7127 and we'll walk you through it.

What does it cost to ship a rebuilt vacuum pump?

Rebuilt pumps are heavy freight: a Stokes 412J-14 ships at roughly 2,200 lbs, class 85, on a custom skid. Shipping cost depends on destination, carrier, and freight class. We can arrange common carrier shipping or you can schedule your own carrier for pickup. Local delivery in West Michigan is also available depending on location.

Can I pick up my pump in person?

Yes. Our facility at 220 Lamoreaux Dr NE, Comstock Park, MI 49321 is open for customer pickup during normal business hours. Call ahead at (888) 633-7127 or (616) 363-6150 to confirm your equipment is ready and to coordinate timing.
