Seal Supply Systems

The EagleBurgmann BestFlow is a temperature-controlled "money-saving valve" for double seals on which the barrier water connection extends directly into the seal chamber, e.g. Cartex-DN.

The DHE consists of an accumulator, a pressure gauge with a shut-off valve and a check valve. The DHE can also be retrofitted to a SPA (Conversion kit no.: DHE140/R001-00).

The pressure control unit is used for setting different levels of barrier pressure when supplying several individual mechanical seals via an SPA with a VTE. There is a choice of four basic types.

With the EagleBurgmann DRU system it is possible to supply barrier fluid to double and tandem mechanical seals for a broad range of applications. The maximum operating pressure of 63 bar applies to the housing of the pressure booster, i.e. the process/medium pressure at the connection must be lower and is conditional on the transmission ratio:
DRU2063/A001 up to 57 bar
DRU2063/A002 up to 42 bar

Circulation in accordance with API 682 / ISO 21049: Plan 53C

Circulation pumps of the eSPU6 series are canned motor pumps, designed as screw pumps with radial stage.
The ideal field of application are closed high pressure circuits in process hydraulic systems.
For this purpose the eSPU6 is a real and inexpensive alternative to glandless centrifugal pumps. The eSPU6 pumps are not self-priming, which means that the pump circuit must be well vented.

Gas supply systems of the GSS range are specially designed for contact-free operated, gas-lubricated mechanical seals. The gas supplied from the supply network (e.g. air or nitrogen) is regulated/monitored by the GSS in accordance with the requirements of the seals being supplied. The GSS systems are equipped with alarm and/or switch-off points depending on specific safety requirements. Centralized monitoring of the measurement values is also possible on request.

Circulation in accordance with API 682 / ISO 21 049: Plan 72, Plan 74

The EagleBurgmann leakage control systems of the LS050 range in accordance with API Plan 65 consist of a leakage collection tank with integrated orifice and overflow pipe along with two shut-off valves. The level can be monitored with the a level switch.

Circulation in accordance with API 682 / ISO 21049: Plan 65

Magnetic separators of the MAA range consist of a pressure casing with integrated magnetic rod. Magnetic separators are used in seal supply systems and any other such systems in which a liquid has to be cleaned of magnetic impurities.

Magnetic filters of the MAF2001 range are inline filters for installation inside pipelines. The combination of magnetic rod and filter element guarantees a high level of efficiency. Magnetic filters are used in seal supply systems and any other such systems in which a liquid has to be cleaned of magnetic and non-magnetic impurities up to a certain size.

Magnetic filters of the MAF203 range are inline filters for installation inside pipelines. The combination of magnetic rod and filter element guarantees a high level of efficiency. Magnetic filters are used in seal supply systems and any other such systems in which a liquid has to be cleaned of magnetic and non-magnetic impurities up to a certain size.

The Multi Flow Unit (MFU) is an economical sealing water management solution for reducing operating costs through minimized rates of fresh water and waste water. The MFU series is available in three basic versions:
MFU-MP: for single seals with flush
MFU-MQ: for seals with quench
MFU-MD: for double seals

These are available for different indicated flow ranges and with numerous system components (e.g. mounting supports, stands, hoses, alarm sensors, etc.) and other material combinations.
Circulation in accordance with API 682 Plan 32, Plan 54, Plan 62.

With the new NonFlow seal supply system it is possible to supply barrier fluid to double and tandem mechanical seals for a broad range of applications. NonFlow systems are equipped as standard with all the necessary system connections and brackets. The system allows for multiple additional components for remote monitoring such as seal temperature monitoring with PT-100 sensors, pressure measurement and leakage detection by flow monitoring.

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.

• Available in a range of different material combinations: suitable for a wide range of demanding operating conditions
• Design for medium temperatures of up to +200 °C (+392 °F)
• Tank made of 1.4571: high resistance to corrosive media
• Integrated overflow for selective discharge of leakage
• Instead of the sight-glass it is possible to use a level switch to monitor the fluid volume
• Combined filling and ventilation filter in the quench fluid tank for reliable operation

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 QFT3000 stainless steel tank is equipped with a sight-glass for monitoring the MIN filling level and can be fastened with a lug fixture.

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

Quench fluid supply systems are used to supply single mechanical seals. They act as a convenient fluid reservoir. The QFT6000 stainless steel tank is equipped with a sight-glass for monitoring the MIN/MAX filling level and can be fastened with a lug fixture.
