The desalination plant Al-Zawrah in the Ajman emirate was planned and built by the Spanish Cadagua. It has a daily drinking water production of approx. 45,600 m³. Seven KSB-RPH pumps are installed in the reverse osmosis plant. They are sealed with EagleBurgmann SHV1 mechanical seals.
Temperature: t = +18 °C … +35 °C (+64 °F … +95 °F), pressure: p = 63 bar (914 PSI), rotational speed: n = 2,770 min-1.
A multistage type MNRO6 high pressure pump of Fapmo, France, was delivered for the reverse osmosis process for the expansion of the seawater desalination plant Sur in Sharqiyah, Oman. It is sealed with an EagleBurgmann SHV2 mechanical seal.
Operating conditions: Temperature: t = +22 °C … +50 °C (+72 °F … +122 °F), pressure: p = 71 bar (1.030 PSI), rotational speed: n = 3,150 min-1.
Fapmo centrifugal booster pumps (type 600700H) deliver water from the Red Sea to the reverse osmosis in Yanbu/Marafiq, Saudi Arabia. The complex consists of a 690 MW power station and two desalination plants with a daily drinking water capacity of 60,000 m³. EagleBurgmann Cartex-QN cartridge seals, supplied in accordance with API Plan 32, reliably seal the pumps.
Shaft diameter: 158 mm (6,22"), temperature: t = 20 °C, 44 °C, 80 °C (68 °F, 111 °F, 176 °F), seal chamber pressure: p = 0.8 barg (11.6 PSIG).
The Spanish company Abengoa operates a reverse osmosis plant as DBOOT project (Design, Build, Own, Operate and Transfer) in Skikda in Algeria. 100,000 m³ of drinking water is procured daily from the Mediterranean Sea. The shafts of the Sulzer inlet pumps (type ZE-400) are sealed with EagleBurgmann H75. Due to the high proportion of sand, EagleBurgmann cyclone separators ZY203 (API Plan 11) are installed to protect the seal.
Pressure: p = 6 bar (87 PSI).
The seawater desalination plant at La Caleta on Tenerife, Spain, produces 10,000 m³ of drinking water each day, thus covering roughly 40 % of the requirement of the surrounding communities. The plant operated by Ayuntamiento de Adeje was built completely underground for ecological reasons. All five Sulzer ZF-200 high pressure booster pumps are sealed with EagleBurgmann type SHV mechanical seals.
Operating conditions: Pressure in the seal chamber: p = 55 bar (798 PSI), rotational speed: n = 1,679 min-1.
In Tungun, a suburb of Gold Coast in Queensland, Australia, a seawater desalination plant in continuous standby operation ensures that the drinking water supply of the surrounding cities is maintained. Nine ERU pumps from Nijhius are deployed in the recirculation of filtered seawater. The shafts of the pumps are sealed with EagleBurgmann SHV1 mechanical seals. They have been operating faultlessly since 2008 without flushing.
Operating conditions: Temperature: t … 28 °C (82 °F), pressure: p = 65 bar (943 PSI), rotational speed: n = 1,500 min-1.
With a daily production amount of 318,500 m³ of drinking water, the Tuaspring Desalination Plant is the largest seawater desalination plant in Southeast Asia. It went into production in 2014 as the second Singapore plant and is operated by Hyflux. Several Sulzer type AFP submersible pumps with 90 mm (3.54") shaft diameter are installed in the seawater removal. They are sealed with an EagleBurgmann MG1 in a special face material combination.
Operating conditions: pH 7 … 9, temperature: t = +26 °C … +36 °C (+79 °F … +97 °F), rotational speed: n = 1,480 min-1.
