Mixtec has the solutions required for gases and corrosive, toxic or hot media at atmospheric pressure, high pressure or vacuum. We take into account the process conditions as well as conditions on site to supply a safe mixer seal that is durable and low maintenance.
Depending on the process requirements, our clients can choose an optimal sealing solution:
- simple lip seal or gland packing for ease of maintenance,
- single mechanical seal,
- double cartridge mechanical seals,
- moat seal.
The mechanical seals can be either of a dry running configuration or a liquid / gas lubricated type. The mechanical seals can be supplied with simple fail-safe seal support systems (Safeunit) or complex engineered support systems depending on the in-vessel contents, pressure and temperature.
The standard drive configuration is able to withstand pressure up to 2000 kPa and with the aid of an auxiliary seal bearing pedestal up to 6000 kPa working pressure.
Rugged cartridge seal housings minimise deflection and extend seal life. Autoclave seals are available in two variants. One has a bearing to steady the shaft and impart the upward axial force into the mounting plate; the other has no bearing and allows the axial force up into the gearbox. For smaller units a swivel stool configuration is available for quick and easy maintenance.
