About this Product

The Sealergy Seals Type H17N is a mechanical seal that is a direct replacement for the industry-standard Burgmann H17N. It is a single, balanced seal with a super-sinus or multiple springs, designed for robust performance in high-pressure and high-temperature applications. It is a variant of the H7N seal and is often used in demanding industrial environments. The H17N is a balanced seal, which allows it to handle higher pressures and speeds with less heat generation and wear on the seal faces. This design makes it suitable for heavy-duty applications where unbalanced seals would fail prematurely. The super-sinus or multiple spring design provides uniform face loading and is independent of the direction of rotation. This ensures reliable performance in a variety of rotating equipment and minimizes the risk of spring clogging. The H17N is built for durability and can be configured with a variety of high-performance materials for its seal faces, secondary seals, and metal components. This allows it to withstand aggressive media and extreme conditions. This type of seal is recommended for the process industry, oil and gas, refining, petrochemical, chemical, and power plant technology. It is a common choice for applications involving hot water and light hydrocarbons, such as in boiler feed pumps. EHJ/TYPE Technical Features Pressure: Vacuum up to 40 bar (580 PSI). Balanced: It features a balanced face design, which allows it to handle higher pressures. Independent of direction of rotation: The seal can be used with shafts that rotate in either direction.

Why Choose the Sealergy Seals Type EH7 ? The EH7 is a balanced seal, which allows it to handle higher pressures and speeds with less heat generation and wear on the seal faces. This ensures good sealing performance under high-load conditions and contributes to a longer service life. The unique stationary, spring-loaded unit of the EH7 allows the seal to operate effectively under high-speed and high-pressure conditions. The seal is designed to handle pressures up to 15 bar and temperatures from -20 °C to +100 °C, with a sliding velocity of up to 10 m/s. As a standard design, the EH7 is easily interchangeable with seals from many other manufacturers, which simplifies procurement and replacement, reducing downtime and maintenance costs.
