As part of its permanent quest for innovation, Pollard has developed an exclusive technology to respond to the operational constraints of wind farms across the world, and by so doing has become a key player in this constantly growing market. In these power stations Pollard technology is used to lubricate reducers and their bearings.
The growth of wind power is an opportunity for Pollard, whose pumps are particularly well-suited for lubrication of this type of equipment.
Technically, Pollard pumps have 3 significant advantages over the other competing technologies:
pumps for lubrication of reducers already sold
The "Reverse plus" system enables the pump to keep its operating direction, regardless of the rotational direction of the pump shaft. This feature means that the transmission is lubricated even when the blades of the wind turbine reverse their rotational direction in certain circumstances.
"CMtec" technology allows the pump to operate over a very wide range of oil viscosities. This advantage allows satisfactory lubrication of the wind turbine's transmission, even when the oil is very cold or very hot. The wind turbine's annual operating time is increased, which improves its profitability.
"CMtec" technology with monobloc blades means that a pump can be designed which is approximately 30% more compact, compared to a gear pump of equivalent capacity. This advantage means that the transmission itself can be made more compact, which is always desirable for wind turbines.
For all these reasons major manufacturers of transmissions for wind turbines have trusted Pollard for many years.
