High Pressure Mechanical Seal for Hot Oil, Chemical, and Corrosive Media Pumps

High Pressure Mechanical Seal for Hot Oil, Chemical, and Corrosive Media Pumps

Mechanical Seals High Pressure utilize welded metal bellow structures that are flexible and balance the effects of pressure on the seal while being compatible with chemicals. Mechanical Seals High Pressure may operate under conditions between –50°C and 204°C and provide a reliable seal even during rapid changes in temperature and under high load conditions. Mechanical Seals High Pressure work very well with chemicals, and work with high-speed, continuous rotation, and crystallization equipment, as well as with large-diameter industrial pumps needing enhanced performance when operated under high pressure conditions.

Advantages of High Pressure Mechanical Seal

Self-Cleaning Rotating Bellows

Centrifugal force removes the build-up of deposits from the surface of the bellows when they are used as the rotating part.

High-Temperature and High-Pressure Stability

The temperature is –50°C to 204°C, and pressure can go up to 27 bar. Metal bellows will give constant spring pressure despite cyclic temperature fluctuations.

Customizable

For pumps with specific designs and high-pressure systems, larger metric sizes (≥110 mm or ≥150 mm) can be made to order.

Applications 🛠 High Pressure Mechanical Seal

Welded Metal Bellows Seals for High Temperature Pumps

Welded metal bellows seals are designed to provide for reliable axial flexibility in hot oil pumps and reactor circulation pumps that will be exposed to extreme temperature variances.

Welded Metal Bellows Seals for High Pressure Pump Systems

The welded metal bellows seals are suited for various applications requiring balance on sealing during their loading. Examples are Booster Pumps, Chemical Transfer Pumps & High Pressure Water Condensers.

Welded Metal Bellows Seals for Corrosive Pump Applications

The welded metal bellows seals are made to accommodate all types of corrosive materials including acids, bases, and chloride-based materials. They will use corrosion-resistant materials such as 316, AM350, Titanium, and Hastelloy C.

Welded Metal Bellows Seals for High Speed Machinery Applications

The dynamic balance of the welded metal bellows, with their non-blocked bellows structure, allows them to be used in pumping applications at rotational speeds exceeding 5000rpm.

Welded Metal Bellows Seals for Crystallising Pump Applications

Welded metal bellows seals are used to prevent pump media from becoming solidified typically like certain types of salts, alkalis, fertilizer, and many other chemicals. This is commonly done through the use of a welded metal bellows seal. This is achieved through preventing the solids formed during the crystallising process from accumulating inside the seal.

FAQ

Should a lubrication or flush system be used?

For clean fluids, there is no requirement for any special treatment. For solids or crystallizing media, flushing or filtering may help minimize face wear.
Yes. Metric sizes ≥110 mm or ≥150 mm (depending on the series) can be manufactured according to a specific pump's requirements.
Minimize thermal shock to the bellows. Keep the temperature within the design range. Periodically inspect for leakage, wear, and condition of bellows.
