All efficiencies are based on full (untrimmed) impeller.

The minimum efficiency index (MEI) is based on the full impeller diameter.”

MPP's specialists repair the damage and enlarge the impeller diameter.

The minimum efficiency index (MEI) is based on the full impeller diameter.

With a runner diameter of 10.3 meters, these are the largest Kaplan units installed in Russia.

Various new impeller wheel diameters and motor sizes permit a choice of the most efficient and economical pump.

The pump weighs around 20 tonnes and has an impeller diameter of more than 1.5 metres.

With 7m impeller diameter at a drop height of 25m, Kaplan turbines were installed.

With a 7.5 m rotor diameter, the turbines are among the largest in Europe.

The indices relate to the respective impeller diameter.

The required impeller diameter can be determined easily using following formulae:

The pertaining impeller 9 diameter 24 measures about 112 to 113 mm.

With the larger impeller diameter, lower pumping speeds are necessary, so that considerably higher durability is achieved.

The fan units are available as Motorised Impeller or Fan Module (Plug Type) in sizes 315 – 560 mm wheel diameter.

Three of these locomotives were also produced for the Palatinate Railway ("Pfalzbahn") as the T 4.II, but these had different dimensions, including smaller driving and carrying wheels.

A doubling of the motor speed would increase the n q value to 20 min ?1, which enables the reverse conclusion to be drawn that the blower impeller design according to the invention leads to the fact that with even relatively low speeds, compared with the impeller diameter, good results can be obtained.

The cover has on one or more bolthole circles (as a function of the impeller diameter) bores (3) corresponding to the number of blades.

According to certain preferred embodiments, it has proven advantageous toward a further reduction of the radial forces if the upstream edges of the rib parts are disposed on circles with the diameter Dr, whose ratios to the impeller diameter D2 are in the range of ##EQU3##

At high pressure ratios, i.e., in the case of high enthalpy gradients in this case, the gas volume flow rates are still very low at the beginning of the expansion, and require small impeller diameters to achieve optimal volume flow rates.

The reduction of the shaft diameter for the sub-block remote from the drive permits an increase in the radial thickness of the hubs of the impellers on the inflow or upstream side without necessarily changing the hydraulic parameters such as the impeller diameter and the specific rotational speed or wheel form characteristic.

The OSSBERGER Cross Flow Turbine of 1250 mm runner diameter will go into service in Turkey with the following power figures:

The best efficiency and further energy savings can be achieved by driving the pump with a variable-speed drive (VSD) and a maximum diameter impeller.

Each pump has an impeller diameter of 1,950 millimeters and a power of 5 megawatts at the nominal head of 26.6 meters and the nominal flow rate of 15 cubic meters per second.

Their impeller diameters are usually at or near the maxi- mum diameter for the casings, and the casings are just large enough to accommodate the existing aero assembly, leaving very little room for changes.

A special graph that indicates a pumps performance: in fact the diagram shows curve formed by flow rate and head values, indicated in reference to a specific type of impeller, a diameter and a particular pump model.

Moreover, it has proven to be advantageous for the ratio of the maximum outer dimension K of the housing to the impeller diameter D to be 1.15 at the maximum.

Advantageously, the first section is arranged in the middle of the apex region, the second section on an outer edge region of the apex region and the third section on an inner edge region of the apex region, in each case with respect to the impeller diameter of the at least one blade.
