Mechanical Seals for Pumps
Mechanical seals for pumps are designed to control leakage where the rotating pump shaft passes through the stationary pump casing. A mechanical seal creates a sealing interface around the shaft while still allowing it to rotate during operation.
Dura Pump supplies pump mechanical seals for a range of applications and liquids, with OEM and aftermarket options available. Our range includes different mechanical seal configurations, including double mechanical seals, allowing the appropriate pump seal to be selected according to the application and operating requirements.

What Is a Mechanical Seal and How Does It Work?
A mechanical seal is used to control fluid leakage around a rotating shaft. In a pump, the mechanical seal sits where the rotating shaft passes through the stationary pump casing, creating a controlled seal between the moving and stationary parts of the equipment.
A typical pump mechanical seal uses two precision sealing faces: one rotates with the shaft while the other remains stationary. These faces work together to contain the pumped fluid while allowing the shaft to continue rotating.
This makes mechanical shaft seals an important component in maintaining pressure within the pump and reducing uncontrolled leakage during operation.
Pump Mechanical Seals for Different Applications
The correct pump mechanical seal depends on the pump, the liquid being handled and the operating conditions. Different mechanical pump seals are available to suit varying applications, with the seal configuration and materials selected according to the requirements of the system.
Dura Pump can support the identification of a suitable mechanical seal for a pump, whether an OEM replacement or an aftermarket option is required. Double mechanical seals are also available where the application requires a different sealing arrangement.
Mechanical Shaft Seals and Pump Leakage
Mechanical shaft seals are positioned around the rotating pump shaft to help contain the pumped liquid within the equipment. By creating a controlled interface between the rotating shaft and stationary pump components, the seal helps prevent fluid escaping from the pump casing during operation.
If a pump seal is unsuitable for the application or becomes worn, its ability to control leakage can be affected. Selecting the correct mechanical seal for the pump and operating conditions is therefore important for reliable pump operation.

Mechanical Seal FAQs
A mechanical seal is used to control leakage around a rotating shaft. In pumps, it creates a sealing interface between the rotating shaft and stationary pump components, helping contain the pumped liquid while allowing the shaft to rotate.
A mechanical seal for a pump helps prevent the pumped fluid from leaking along the rotating shaft and out of the pump casing. It allows the shaft to rotate while maintaining a controlled seal around it.
A pump mechanical seal is a mechanical shaft seal specifically used within a pump. It normally uses a rotating sealing face and a stationary sealing face to create the interface required to control leakage around the shaft.
Yes. Different mechanical seal designs and configurations are used according to factors such as the pump, pumped liquid and operating conditions. Dura Pump’s existing range includes seals for different applications and liquids, double mechanical seals, and OEM and aftermarket options.
Yes. The current Dura Pump range includes both OEM and aftermarket mechanical seal options.
The correct mechanical seal depends on the pump and its operating conditions. Providing details of the pump, existing seal and application can help determine an appropriate replacement. Seal selection can be influenced by factors including the fluid, pressure, temperature and equipment operating conditions.
