Mechanical Seal Replacement Without Emptying the Tank
Fixed side-entry mixers are specially designed for efficient blending and circulation of products stored in large tanks. They are particularly suitable for crude oil, fuels, diesel, petroleum derivatives, mineral products, and bio-based products.
A key advantage of this mixer is the built-in shut-off system, which allows the mechanical seal to be replaced while the tank remains full. The mixer does not need to be removed from the tank, and the gearbox does not need to be dismantled, making maintenance faster and easier while reducing process interruption.
The mechanical seal is positioned for easy external access and is mounted on a removable bush, allowing quick inspection, servicing, and replacement.
The mixer can be supplied with an inclined mounting flange, typically at 7° or 10° depending on the mixer size. This arrangement eliminates the need for a separate inclined tank nozzle, helping to reduce overall installation weight and projection from the tank. The compact, self-supporting design provides good stability during operation and normally avoids the need for additional tie rods.
Optional configurations include
- Variable-angle system (AV)
- Control and alarm instrumentation
- Seal leakage detection
- ANSI or API mounting flanges
Description
A heavy-duty side-entry mixer designed for blending, circulation, and maintaining uniform product conditions in large storage tanks. Its integrated shut-off system allows mechanical seal maintenance or replacement without emptying the tank or removing the complete mixer, helping minimise downtime and simplify maintenance.
