1. What is the difference between a GWTSK (Tip Seal Kit) and a GWMMK (Major Maintenance Kit)?

A GWTSK is designed for scheduled minor maintenance (typically replaced every 8,000–16,000 operating hours or when ultimate vacuum drops slightly). It focuses on replacing the dynamic sealing components (tip seals, shaft seals, and O-rings). A GWMMK is a comprehensive overhaul kit recommended for major service intervals, replacing both sealing parts and rotating drive components such as bearings and crank pins.

2. Is this tip seal kit compatible with GWSPB (Variable-Speed) series pumps?

No. This GWTSK kit is exclusively engineered for standard GWSP vacuum pumps and GWSPC compressors. If you are operating a GWSPB variable-speed pump, please select the GWBSK tip seal kit, which is specifically matched to the scroll wrap geometry of variable-speed models.

3. How do I ensure I order the exact-match tip seal kit for my pump?

First, match the kit model to your pump capacity rating (e.g., select GWTSK300 for a GWSP300 pump). Crucially, you must provide your pump’s Part Number (P/N) when adding the item to your cart. Because Geowell scroll pumps undergo continuous engineering iterations and internal structural upgrades, the unique Part Number (laser-stamped on the pump housing or metal nameplate) is the only way to verify 100% mechanical compatibility with your specific pump revision.

4. Can I purchase tip seal kits for multiple pumps at once / enter multiple Part Numbers?

Yes, absolutely. You can order kits for multiple pumps in a single transaction:

Select the total quantity of tip seal kits you need.
Click outside the input field (or anywhere on the blank area), and the system will automatically generate the corresponding number of Part Number input boxes.
Enter the specific Part Number for each individual pump.

Note: If you are purchasing multiple spare kits for the same pump, simply enter that pump’s Part Number in each box.

5. Does the tip seal kit come with installation instructions?

Yes. Each GWTSK kit includes a step-by-step printed replacement guide showing the proper seal orientation, groove seating, and casing assembly instructions. In addition, detailed video tutorials are available on our Technical Support Page to guide you through the replacement process smoothly.

Where can I find the Part Number?

The Part Number is engraved on the pump head of your vacuum pump. It serves as the unique identifier of your product and helps us match the correct major maintenance kit for your equipment.
