In its constant quest for innovation, Pollard has developed exclusive technology to meet the operating parameters of wind farms worldwide positioning itself as the player of choice on this growing market. Pollard technology is used by these power stations for gearbox lubrication and bearing lubrication.
The development of the wind power is a true opportunity for Pollard who’s pumps are particularly suitable for the lubrication of this kind of equipment.
Technically speaking, the Pollard pumps have 3 major advantages comparing to the competitors’ technologies:
The « Reverse plus » system allows the pump to keep the same flow direction (constant in/out ports), whatever the direction of rotation of the pump shaft. This system maintains the transmission lubrication even when, under certain conditions, the wind turbin blades reverse their sense of rotation.
The monobloc blades « CMtec » technology allows the pump running within a very large oil viscosity range. This advantage maintains an optimal lubrication of the wind turbin transmission, even if the oil is cold (viscous) or hot (fluid). The wind turbin annual running period is extended which improves its profitability.
With the monobloc blades « CMtec » technology the pump is 30% more compact comparing to a gear pump with an equal capacity. This advantage makes the transmission itself smaller, which is required for the wind turbins.
For all these reasons since a long time the biggest transmission manufacturers trust Pollard.
