A turbine, wherein a propeller is mounted to said turbine, rotatable around a propeller axis, wherein a multi piston pump is provided, said multi piston pump being drivable by said propeller for pressurizing a pumping fluid, wherein the multi piston pump comprises a central part and a drive ring extending around the central part, wherein the central part comprises a series of piston-cylinder assemblies which are each compressible and extendible in a respective radial direction with respect to a common central axis, wherein each of the piston-cylinder assemblies is directly or indirectly engageable by the drive ring for radial compression thereof, in particular for pressurizing said pumping fluid, wherein at least one of the piston-cylinder assemblies is provided with a hydraulic and/or pneumatic biasing means for biasing, at least selectively biasing, at least part of that piston-cylinder assembly towards engagement with the drive ring, in particular substantially independent of and/or complementary to a biasing by a pressure of pumping fluid at that piston-cylinder assembly.
