Features of the ASUMB Pelton turbine

The ASUMB Pelton turbine is designed for high-pressure, low-flow applications. Its key feature is its pulse design, where a narrow water jet strikes the impeller bucket, transferring nearly all of its energy.

The turbine efficiency reaches 90–93%, which is one of the best indicators in the class of high-pressure hydroturbines.

Benefits and effectiveness

High efficiency at high pressures
Efficient operation on seasonal and unstable water flows
Suitable for the reconstruction of old hydroelectric power plants and the construction of new high-pressure stations
Versatility for industrial, municipal and small hydropower plants

Reliability and durability

The ASUMB Pelton turbine is distinguished by Austrian quality:

high-strength cast buckets
anti-corrosion coatings
balanced rotor
high-quality bearing units

The service life of the equipment is 30–50 years with proper operation.

Ease of maintenance and operating costs

The ASUMB Pelton turbine requires minimal maintenance and does not require complex hydraulics:

checking injectors
inspection of buckets
inspection of seals and bearings

Routine maintenance is carried out once every 12–18 months, and major repairs are carried out once every 10–15 years, which reduces operating costs.

The working principle of the Pelton turbine ASUMB

Water is supplied through a pressure water pipe and nozzles, forming a narrow stream.
The jet hits the impeller bucket, changing direction by 180° and losing almost all of its energy.
The energy of the water is transferred to the shaft, driving the generator.
The generator produces electricity.

The pulse principle ensures stable, safe and economical operation at high pressures.

Where are ASUMB Pelton turbines used?

High-pressure hydroelectric power plants
Mini hydroelectric power plants on mountain rivers and streams
Autonomous stations in hard-to-reach regions
Municipal and industrial micro-hydroelectric power plants
Reconstruction of old Soviet hydroelectric power plants

Particularly suitable for Kyrgyzstan, Kazakhstan, Georgia, Armenia, Altai, the Caucasus and any mountainous areas.

General concept: The Arym River has a natural elevation difference, making it ideal for a cascade of mini-hydroelectric power plants. The hydrological regime is snow-glacial: the maximum flow rate is up to 7 m³/s during the melting period, and the minimum is about 1.3 m³/s in winter. A single pressure penstock with a diameter of 1400 mm and a flow velocity of approximately 3 m/s is used, providing an average annual operating flow rate of 4.62 m³/s. ⚙️ 2. Cascade structure: The cascade consists of four stages, each with its own pressure head and diversion length. The effective total head of the cascade is ≈1065 m, with total losses of only 38.9 m. No. Name Effective head, m Capacity, MW 1 Arym-1 ≈254 ≈11.0 2 Arym-2 ≈224 ≈9.6 3 Arym-3 ≈195 ≈8.4 4 Arym-4 ≈392 ≈11.7 Total: ≈40.7 MW ⚡ 3. Energy potential The total installed capacity of the cascade is about 40.7 MW. Turbine equipment has an efficiency of up to 85%, which guarantees high efficiency and stable generation. 💰 4. Investment attractiveness The project belongs to the category of highly profitable renewable energy facilities. At a tariff of 4.42 soms/kWh, the expected annual revenue provides a payback period of 4.5 to 6 years. Advantages: minimal construction risks; simple installation of a single 1400 mm diameter string; reduced capital expenditures on metal structures and supports; scalability (a second string for increased capacity). 🏗️ 5. Conclusion: The cascade option on the Arym River is a technically feasible and economically feasible project, ensuring stable power generation, a rapid return on investment, and long-term operational reliability. The project is ready for further design, approval, and investment.
