Features

Quench fluid supply systems are used to supply single or tandem mechanical seals. They act as a convenient fluid reservoir. The exchange of fluid takes place by the thermosiphon principle or by forced circulation, e.g. with a pumping screw. The QFT1000 is made of transparent polyethylene, complete with clips made of stainless steel. The QFT1000 is resistant to water, glycerine, glycols and methanol; not resistant to mineral oils and toluene.

Supply of mechanical seal based on API 682 / ISO 21049, Plan 51.

Advantages

• Excellent value for money
• Transparent polyethylene: fluid level is read off directly on the quench fluid tank
• Resistant to a wide range of quench media
• Quickly and easily installed
• Combined filling and ventilation filter in the quench fluid tank for reliable operation

Recommended applications

• Chemical industry
• Food and beverage industry
• Pharmaceutical industry

Functional description

Quench fluid systems are employed:

• to absorb leakage
• to monitor the leakage rate (e.g. through periodic reading of the level in the tank)
• to lubricate and to cool the outboard mechanical seal in a tandem arrangement
• to prevent icing
• to protect against dry running
• to stabilize the lubricating film
• to exclude air from the media in order to prevent a reaction with oxygen in the air

Notes

Install the quench fluid tank approx. 1 … 2 m (3.3 … 6.6 ft) above the mechanical seal. Install connection pipes to the mechanical seal with low flow resistance. Pipes must vent automatically in the direction of the tank. It is imperative that air pockets are prevented. The minimum filling level must always be above the connection socket at the side (in the case of the thermosiphon principle). Quench fluid systems can be operated in two different modes.

Features

With the EagleBurgmann TS1016 thermosiphon system it is possible to supply buffer/barrier fluid to double and tandem mechanical seals for a broad range of applications. The TS1016 thermosiphon vessel is available in 2 standard sizes with flat ends, sight-glasses for level monitoring and with or without cooling coil. TS vessels are equipped as standard with all the necessary system connections and brackets. The modular system allows the TS1016 vessels to be combined with a wide range of system components such as, e.g. level switch, circulation pump, hand refill pump, thermometer, base frame, etc.

Circulation based on API 682 / ISO 21 049: Plan 52, Plan 53A

Advantages

• Available in 2 standard sizes
• Modular system: combination with a wide range of system components possible
• Vessel made of 1.4571 stainless steel / borosilicate sight-glasses: suitable for universal applications
• All system connections on the face sides
• Available with or without cooling coil
• Low space requirements because of compact design

Standards and approvals

• PED 2014/68/EU (Design and production in accordance with EU Pressure Equipment Directive)
• SELO, TR CU on request

Recommended applications

• Chemical industry
• Petrochemical industry
• Pulp and paper industry
• Food and beverage industry
• Water and waste water technology

 Functional description

The TS system performs all the basic functions of a buffer/barrier system for the operation of double seals:

• to pressurize the buffer chamber
• leakage compensation
• buffer/barrier fluid is circulated by thermosiphon effect or forced circulation system
• to cool the seal
• to selectively absorb product leakage and prevent dry running (tandem arrangement)

Use compressed air or nitrogen for pressurization.
