Saudi Arabia

A chemicals company in the Middle East uses the refrigerant R134A-Freon in the production of toluene diisocyanate (TDI). Shortly after the refrigeration plant is commissioned, a magnetic coupling pump fails. Quick help was called for, EagleBurgmann delivered the O-ring seal H75VN with DiamondFace.

Operating conditions: d₁ = 90 mm (3.543”), p₁ = 12.4 barg (179.8 PSIG), t = 45 °C (113 °F), v_g = 6.5 m/s (21.3 ft/s)

Japan

In a chemical plant in Japan, a pump is used to transport molten sulfur. Crystallized sulfur in the area of the shaft seal led to contamination and enormous maintenance costs. Since retrofitting to the EagleBurgmann SulfurAce mechanical seal with an integrated QS300 quench seal, the pump offers optimal availability. The working environment is clean and employees are secure from hazardous substances.

Netherlands

The drinking water pump station in the Dutch town of Manderveen deploys vertical type CFU centrifugal pumps from Johnson Pumps. They have been reliably delivering over 3.6 million cubic meters of drinking water in continuous operation since 2013. The pumps are sealed with EagleBurgmann M7N mechanical seals with drinking water approved materials. Further operating data: Temperature: t = 15 °C (59 °F), pressure: p = 6 barg (87 PSIG), rotational speed: n = 1,450 min^-1.

Germany

At the Wahnbach dam approx. 25 km southeast from the German city of Cologne, a pumping station delivers untreated water for the drinking water supply of approx. 800,000 inhabitants in the Bonn, Rhein-Sieg, Ahr region to the nearby treatment plant. The water is extracted in various depths from the approx. 50 meter deep reservoir with a pumping capacity of 1,600 ... 3,200 m³/h. Installed here are Ritz pumps which are sealed with EagleBurgmann Cartex-SN cartridge single seals.

Operating conditions: Pressure: p = 11 bar (160 PSI), rotational speed: n = 1,400 min^-1.

Montenegro

An extensive major project for water procurement and supply of the South European country of Montenegro was realized by Xylem Austria, Lowara Vogel. The untreated water is first delivered from the Bolje Sestre water extraction station by four vertical Vogel volute casing pumps to the treatment plant and then on to the Reljici pumping station (photo) located 30 km away. Here the drinking water is pumped by six Vogel multistage pumps to the high-level tank located 6 km away. From there it supplies the northern coastal area (73 km towards Croatia) as well as the southern coastal area (34 km towards Albania). All pumps are equipped with EagleBurgmann types M74 and H74 mechanical seals.

Denmark

Grundfos BioBooster A/S develops and distributes a new generation of compact, decentralized and modular sewage treatment plants, e.g. for water treatment of hospitals (shown here the system of the hospital at Herlev, Denmark), among others. These plants run maintenance-free in continuous operation. Their central components are new types of BioBooster filter units, each of which contain three EagleBurgmann MG1 shafts seals. They effectively prevent contaminated water from leaking into clean water.

Netherlands

SPX-Johnson type CFB 200-400 pumps for the recirculation of separated water are installed in a membrane ultrafiltration plant of the Dutch Water Treatment Company. The medium is very aggressive, has a solids content of 50 mg/l and exhibits dissolved solids of up to 3,800 mg/l. The mix also includes toxic hydrogen sulphide (H2S) which requires reliable leakage detection. The pumps are sealed with EagleBurgmann Cartex-DN double seals. The seals are supplied by means of the EagleBurgmann TS1016 system as per API Plan 53.
