- Premium Quality:Our GSM5 Gasket set is made from premium quality materials that can withstand the fluids being pumped and are resistant to high temperatures and pressure. It is used with the GSM25 Gear Pump, a positive displacement pump frequently used for pumping viscous liquids.
- Replacement Gasket Set: The GSM25 Gear Pump is a non-serviceable pump, which means that it is not intended to be disassembled for repairs or maintenance. However, it is important to note that the gaskets will need to be changed if disassembly is necessary for any reason.
- Guarantees Tight Sealing:When the gaskets are placed correctly, they provide a tight seal that prevents leaks and makes the pumps more effective.
- Install in a snap!:Our GSM25 Gasket Set is designed to fit our GSM25 Gear Pump, which allows quick and easy installation. This makes it possible to get the pump up and running as soon as possible and minimizes downtime.
The Goldstream Advantage
Protect your investment by using only genuine Goldstream seals. Generic gaskets often lack the necessary thickness and chemical resistance to handle hot oils, which can lead to cavitation and loss of prime.
For complete 3-Phase industrial pump assemblies that utilize this gear pump technology, visit our Industrial Series Hub.
Note: Ensure all mating surfaces are thoroughly cleaned and free of old gasket residue before installation. Torque housing bolts to factory specifications to ensure a uniform, reliable seal.
FAQs

2. Can I use a Goldstream pump for my home project?
Absolutely. Our Monster Series is portable and self-priming — no tuning or tricks needed. Plug it in and move fluid.
3. Can Goldstream pumps be used in marine or outdoor conditions?
Yes. Goldstream pumps are tested in real-world marine, biofuel, and industrial conditions — heat, humidity, and long runtimes.

Flush with a compatible fluid after each use and keep seals clean. That's it — our gear pumps are built to run with minimal fuss.
