KSB extended portfolio with vertical turbine pumps

Tuesday, October 23rd, 2018 von admin

The KSB Group extended its portfolio by adding a comprehensive programme of vertical turbine pumps. The so-called B Pumps are multistage vertical turbine pumps with a submerged hydraulic system. The pump sets comprise a discharge casing assembly, a column pipe and a pump bowl assembly. In total, customers can choose from 17 sizes with three different impeller types.

  • The pump sets cover heads of up to 200 metres.
  • Flow rates of up to 720 l/sec.
  • Available with one to 25 stages,
  • with stage casing diameters ranging from six to 24 inches.

Impeller improves suction characteristics in high-pressure pumps

Tuesday, July 24th, 2018 von admin

KSB experts developed a special impeller for its Movitec multistage high-pressure pumps. This new impeller significantly improves these pumps’ suction characteristics (NPSH value).

It proves its worth particularly in applications with critical inlet conditions (e.g. boiler feed applications) as well as applications in which the pump is required to take in water from low-lying tanks or at higher temperatures. Under these conditions, a pressure drop in the intake area may cause cavitation to occur in the first pump stage. This can result in excessive wear of pump parts or motor bearings as well as a reduced service life of the pump due to damaged parts and an unbalanced hydraulic system.

The new impeller is offered as an alternative to the standard product.

Sulzer Extends the High-Efficiency Water Pump Range

Friday, September 23rd, 2016 von admin

smd_small_fullSulzer introduces an extension to the SMD axially split pump range towards lower flows and implements a higher level of standardization for cost-effective solutions and short delivery times. The SMD pump range is developed for a wide range of high-volume flow applications where raw, clean, sea, or brackish water is pumped. Such applications are water abstraction, water transport, desalination, water treatment, supply, and distribution. The pumps can also be used for firefighting, drainage, or distribution of heating and cooling media in residential and industrial systems.

Reich: Flexible couplings for Diesel driven fire pumps

Thursday, July 30th, 2015 von admin

reichkleinThe highly flexible VSK coupling is an integral component for connecting the combustion engine to the right-angle gear drive of the fire pump system. By using the VSK highly flexible coupling, the drive train can be protected from dynamic overload, reduce resonance-induced vibratory torques and provide a convenient connection between the combustion engine and drive shaft.
