Essential Vacuum Pump Spare Part Checklist

Essential Spare Parts for Industrial Vacuum Pump Owners

*Note, a Catalog of referenced parts and part numbers are listed at the end of this article*

For industrial vacuum pump owners, having key spare parts readily available is crucial for preventing downtime and costly repairs. This article highlights frequently used maintenance components that every pump owner should stock, focusing on two of the industry's most popular vacuum pumps: the GLV 1.5 Rotary Piston Pump and the GLV 3.0 Rotary Piston Pump.  Additionally, the same GLV 1.5 parts apply to the Stokes 212H-11 pump, while GLV 3.0 parts correspond to the Stokes 412H-11 pump.

 

Key Spare Parts to Keep on Hand

 

1. Seals & Gaskets

These help maintain airtight integrity, preventing leaks and performance drops. Common types include:

  • Vacuum pump gaskets.  In regards to both the GLV 1.5 and GLV 3.0 pumps, these most common gaskets are the valve plate gasket, the reservoir cover gasket, and the oil baffle gasket.
  • Seals.  The Mechanical Shaft Seal requires periodic replacement.  The 1.5 pump requires 2 of these seals, and the 3.0 requires 1 seal.

2. Filters

If you have an Oil Mist Eliminator on your pump, exhaust filters protect your environment from contaminants and debris.  Keep stock of:

  • Exhaust filters.  The fine mist emitted by Oil-sealed pumps will build up on your filter, so periodic replacement will be necessary.

3. Lubricants & Fluids

Proper lubrication ensures smooth operation and reduces overheating.

  • Vacuum pump oil.  Vacuum pumps require specific oils that are aligned with their specifications – utilizing other oils may result in malfunction and safety issues.

4. Drive Components

Vee Belts keep the pump running efficiently by ensuring proper motion.

  • Belts.  Due to wear factors such as friction and time, Vee Belts stretch and break.  The 1.5 pump utilizes a set of 3 Vee Belts.  The 3.0 pump utilizes a set of 4 Vee Belts.

5. Electrical Components

For pumps with electrical controls, these parts are vital:

  • Solenoids.  A solenoid valve prevents oil from flooding the pump in the event of a power loss issue or pump malfunction.  There is a standard replacement for the 3.0 pump.  For the 1.5 pumps, the solenoids come in both Low-Voltage (LV) and High-Voltage (HV).

6. Minor Rebuild Kits

·       Clappers, Springs, & Gaskets.  We find that our customers typically perform minor maintenance rebuilds every 6-9 months.  That frequency is completely dependent on the pump conditions, such as extreme temperatures, harsh chemicals, etc.  Minor Rebuild Kits are available for both the GLV 1.5 and the GLV 3.0 pumps.

Stocking these spare parts ensures smoother operations and minimizes downtime.
