Submersible borehole pumps for very high heads

Tuesday, November 20th, 2018 von admin

These new submersible borehole pumps developed by KSB have a diameter of up to 50 inches, i.e. 1250 mm, and a drive rating of up to 5 MW. These pumps will be capable of handling

  • flow rates of up to 5000 m³/h
  • at heads of up to 1500 m.

Compared with dry-installed pump sets, the advantage of submersible borehole pumps is -acc. to an information of the manufacturer- “the notably longer service life and the fact that pumps with wet motors are not compromised by flooding.” KSB is one of the few manufacturers worldwide to offer double-entry designs for particularly high load conditions alongside “normal” single-entry designs.

This double-entry design was originally used for drainage applications in mines. The heads required in these applications would have created very high axial thrusts in single-entry pump designs, placing extremely high loads on the bearings. The back-to-back impeller arrangement employed in double-entry designs not only reduces the axial thrust but also the associated bearing loads.

Providing the best water in Karelia

Tuesday, July 10th, 2018 von admin

The Northwest of Russia literally flows with water. An area known for huge lakes and vast wetlands. Petrozavodsk is the capital, and the largest city, of the republic and most of the 300,000 inhabitants get their drinking water from the nearby Lake Onega. But some new settlements on the outskirts of the city have chosen another source. “We get our water supply from an aquafer, that covers most of southern Karelia. Three large pumps from Grundfos deliver water to our building complex with around 5,000 people,” explains Vitaliy Markov, General Manager of Drevlyanka Vlll – a part of Chistiy Gorod.

Systematic flow metering – instrumentation for water supply in desert region

Tuesday, January 30th, 2018 von admin

Aguas de Saltillo, the water utility company which serves the city of Saltillo in Mexico, is responsible for supplying drinking water to a population of around 850,000. To ensure a reliable supply in this arid desert city, the company relies on a water network which draws from several reservoirs with the aid of process instrumentation from Siemens. The Sitrans F M MAG 8000 electromagnetic flow meters used here are outstandingly robust, durable and reliable, as well as requiring minimal maintenance. Over a hundred of these devices have now been installed in the Aguas de Saltillo network.

Green pumps for a green stadium

Tuesday, January 16th, 2018 von admin

Croke Park is a major Gaelic Athletic Association (GAA) sports venue located in Dublin that hosts events for a number of sports. Croke Park has been at the heart of Irish sporting life for over a hundred years, it is not only an iconic landmark but also the third largest stadium in Europe.

Since 1884 the site has been used primarily by the GAA to host Gaelic games, most notably the annual All-Ireland finals in Gaelic Football and Hurling. In honour of Archbishop Thomas Croke, one of the first GAA’s first patrons, the stadium was renamed to Croke Park.
