Ordering Tip & Version Verification

Product configurations may vary by manufacturing date and design revision. To ensure you receive the correct kit and avoid maintenance delays, please confirm your pump model, Part Number before buying this major maintenance kit.

Need tip seals only? Click the GWBSK Series to purchase the tip seal kit separately.

1. Is this kit compatible with standard GWSP series pumps?

No. The GWMMKB kit is exclusively engineered for the GWSPB variable-speed series to match its specialized motor geometry and drive components. If you are operating a standard industrial GWSP pump, please select the GWMMK major maintenance kit instead.

2. How do I ensure I order the exact-match kit for my GWSPB pump?

First, match the kit model to your pump’s capacity rating (e.g., select GWMMKB300 for a GWSPB300 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.

3. Can I purchase major maintenance 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 required quantity of kits.
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.

4. When should I perform a major overhaul on my GWSPB pump?

We recommend a scheduled major overhaul during regular long-interval service periods, or whenever you notice a decline in ultimate vacuum, increased operating noise/vibration, or after prolonged continuous operation in demanding conditions. Performing timely overhauls restores factory-grade sealing and extends the operational life of the pump.

5. Does the kit come with installation instructions and technical support?

Yes. Each GWMMKB kit includes a detailed step-by-step service guide to assist with proper disassembly, part replacement, and reassembly. Furthermore, you can access comprehensive video tutorials and technical documentation on our Technical Support Page at any time.

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.
