Fish friendly Pump Turbine with Concrete Volute - BVOP
The BVOP VVT is an innovative pump turbine with a concrete volute, developed by Stork. It operates efficiently on both pumping and turbine modes and is designed to be fish-friendly, enabling energy generation during water intae without harming aquatic life. This solution is ideal for converting existing pumping stations, either by retaining the original volute or integrating a new concrete volute. BVOP VVT: SUSTAINABLE FOR THE ENVIRONMENT AND AQUATIC LIFE The BVOP VVT pump turbine is sustainable in several ways: • With the BVOP VVT pump turbine, the existing wet path via the pump is used for the intake of water to the polder. The pumping station functions as a turbine and generates electricity continuously, which can be fed back into the grid. • The pump has an environmentally friendly bearing and pump shaft seal. Where contact with the pumped medium can occur, the pump is water-lubricated and no grease is used. This prevents pollution of the surface water. • The pump is certified fish-friendly according to the NEN 8775 standard (>97% fish-friendly), for both the pump and turbine function. • The design is robust and executed in such a way that only minimal maintenance is required. • A customer-specific design of the impeller and volute is made based on the requirements of the pumping station. For example, we design an optimally performing pump, based on the desired capacities and head, in combination with optimal operational management. PUMP TYPE: Stork BVOP 120 CAPACITY: 200 m³/min LIFT HEIGHT: 2.42 m TURBINE: 47 kW generated continuously at 3.4 m drop ACTIVITIES: • Conversion to BVOP fish-friendly pump • New impeller and spiral hydraulic design • Pump manufacturing and assembly • Manufacture prefab concrete volute • New concrete block design • Permanent magnet motor 280 kW • FAT test of engine under full load • Installation on site, IBS, SAT
