Cartridge seals in the industry: Basic properties and their importance

Cartridge seals are essential components in many industrial processes, used in everything from pumps to mixers and other rotating equipment. These mechanical seals are available in different types, including single cartridge and double cartridge seals, which can be either single or double acting.

A single cartridge is mounted on one shaft, while the double cartridge is mounted on both sides for increased flexibility in use. Their primary function as a sealing solution is leak prevention by sealing the shaft in pumps.

This is essential to maintain machine efficiency and extend its lifetime. Without effective seals, equipment can be exposed to serious damage, leading to significant operational costs and potentially environmental disasters.

That's why cartridge seals are indispensable for both safety and productivity in industry. They contribute to more efficient and safer production, making them an essential investment in maintenance, reliability and environmental protection in various operating conditions.

Cartridge seal LSC40-F is an excellent single seal designed for leak prevention in rotating shafts. Its balanced design and use of multispring technology ensures both reliability and easy installation. Made from AISI 316 stainless steel and Hastelloy, the cartridge seal's mechanical seal can withstand challenging industrial operating conditions.

It works effectively at temperatures from -15 to +200°C and handles pressures up to 25 kg/cm², making it a versatile sealing solution.

• Single seal for leak prevention in rotating shafts.
• Multispring technology for balanced function.
• Made of AISI 316 stainless steel and Hastelloy.
• Operating conditions: -15 to +200°C.
• Pressure capacity: Up to 25 kg/cm².

The LDC40 Double cartridge seal is ideal for sealing applications that require both robustness and effective leak prevention. This double seal utilizes components such as stainless steel and Hastelloy and shares design concepts with the LSC40-F. With its dual configuration, it ensures excellent sealing solutions, perfect for demanding operating conditions.

The LDC40 Double is designed to operate within the same temperature and pressure ranges as the LSC40-F, making it a reliable mechanical seal.

• The double seal is ideal for demanding sealing applications and particularly suitable for demanding production environments with high wear resistance.
• Optimized to minimize leaks in harsh environments.
• Balanced design with multispring technology.
• Materials include stainless steel and Hastelloy.
• Operating specifications compatible with LSC40-F.

In today's industrial environment, where cost control and energy efficiency are key, choosing the right sealing solutions is necessary to optimize operations, extend lifetime and minimize costs in the long run.

Cartridge seals like the LSC40-F and LDC40 Double play a key role in reducing operating costs and optimizing energy efficiency - including ensuring effective sealing to prevent leaks.

The LSC40-F is a single seal constructed with multispring technology and made from durable materials such as AISI 316 stainless steel and Hastelloy. This sealing solution is designed to withstand demanding operating conditions and minimize friction on the shafts, resulting in a lower energy load for the machines. By choosing the LSC40-F, you can reduce your energy consumption, leading to lower operating costs and longer maintenance intervals.

The LDC40 Dual cartridge seal offers additional benefits with its dual configuration, ideal for high load applications and demanding conditions. This solution not only ensures minimal leakage, but also improves operational efficiency by stabilizing operational processes. The result is more consistent production, fewer unplanned stops and thus reduced costs associated with downtime and repairs.

By investing in the LSC40-F and LDC40 Double Cartridge Seals, you can achieve significant savings and higher efficiency. These investments not only provide an effective seal, but also contribute to a more sustainable operation, which is crucial to stay competitive in today's market.

Yes, both versions can be repaired to achieve a more sustainable operating economy. Together with our partner, we can in most cases replace necessary parts for recycling.

We can supply spare parts for both versions, including O-rings, flange gaskets etc. See illustration below:

The choice between single and double seal configuration depends on the specific operating conditions. Consider factors such as pressure, temperature and leakage control requirements. A double seal is usually recommended for more demanding applications, while a single seal may be sufficient for moderate conditions.

Choose LSC40-F for simple leak prevention and easy installation, ideal for standard applications. Choose the LDC40 Double for demanding environments that need extra robustness and double sealing for optimal leak protection.
