Hydraulic submersible pumps are tremendously useful and versatile pieces of equipment, allowing commercial, industrial and private interests to efficiently and reliably pump huge amounts of water and other liquids out of tanks, reservoirs and aquifers. However, just like any hydraulic system, a hydraulic submersible pumps needs to create extremely high internal pressures to function properly, and these pressures cannot be maintained without strong, reliable gaskets and seals.
The gaskets found in even small, low-capacity hydraulic submersible pumps must be immensely strong to withstand the immense forces generated within hydraulic cylinders. They must also be able to withstand constant exposure to water and common waterborne chemicals. As such, choosing gaskets made from materials that can withstand such hostile environments is critical.
If you need to replace the gaskets in a hydraulic submersible pump or need a large quantity of pre-made gaskets for manufacturing hydraulic submersible pumps, the following commonly used gasket materials are ideal for your purposes.
More properly known as ethylene propylene diene monomer rubber, EPDM rubber is an extremely versatile synthetic rubber that is one of the most commonly used materials for making hydraulic gaskets. It is highly resistant to mechanical wear and stresses and will not perish when constantly exposed to fresh or brackish water. Crucially, it does not become brittle when exposed to cold temperatures, making it particularly suitable for submersible pumps used to pump cold liquids, such as deep well pumps and nuclear reactor pumps.
If you opt for EPDM rubber gaskets for your hydraulic submersible pump(s), make sure you choose gaskets made from commercial-grade EPDM or better. Lesser grades of EPDM may not be able to withstand the extremely high and low pressures within your hydraulic cylinders unless you are running a particularly small, portable pump.
Neoprene is another type of synthetic rubber that is well-suited to making hydraulic gaskets for submersible pumps. It boasts similar resistance to wear and moisture as EPDM rubber, but neoprene is particularly prized for its resistance to a wide range of corrosive chemicals frequently found in contaminated wells, such as petroleum products, solvents and pesticides. This makes neoprene gaskets ideal if you are using your hydraulic submersible pump to extract water from badly polluted wells, aquifers and other water sources.
Silicone has been used as an all-purpose sealing material for decades, but it is just as useful for sealing specialised equipment like submersible hydraulic pumps. While foam silicone gaskets aren't suitable for most hydraulic applications, solid silicone gaskets have the strength and durability you need at a price that is often much lower than gaskets made from other materials.
Solid silicone gaskets are particularly useful for creating seals in portable hydraulic submersible pumps. This is because their physical properties remain unchanged across a wide range of temperatures, making them just as safe and effective whether you use your pump high in the mountains or deep in the desert. Silicone gaskets are also chemically inert, making them another good choice if you intend to pump corrosive liquids or contaminated water supplies.

Hey, there! My name is Dan. If you are looking for a cool new guide to industrial supplies, you have come to the right place. The articles I have published on this blog will help you to develop your understanding of different types of industrial supplies. I'm no expert when it comes to this subject but I'm married to a man who works in this sector. Over the years, he has taught me lots of cool things about his work and I thought it only fair to share some of my knowledge here. I hope you enjoy reading this blog.
