Parker Hannifin is proud to introduce in this catalogue its selection of hydraulic vane pumps especially dedicated to variable speed drive applications. The unique technology of theses hydraulic pumps is allowing a wide range of operating speeds, to take the maximum benefits of modern power transmissions. When driven with asynchronous or synchronous electric motors and piloted by frequency controllers, they operate in the most efficient and reliable ways, allowing maximum energy savings.

Markets:
• Plastic Industrial
• Auto Industrial

Main benefits of variable speed drives:

Energy savings
• Up to 70 % less electric Energy for the E Motor and less or no cooling for the hydraulic equipment
• Lower noise emissions
• Lower total cost of the hydraulic system
• Smaller pump, less valves, less or no cooling, smaller fluid tank, increased lifetime for the components

Product key features:

Reliable performance
These T7 hydraulic pumps have been designed especially for variable speed drives and are offering a wide speed range. Like all our T7 Series vane pumps, the performances do remain very stable over time, making these pumps an ideal solution for modern electro-hydraulically operated machines.

Long lifetime
The fully pressure balanced concept increases the pump lifetime over its full operating range while double lip vanes reduce the sensitivity to fluid pollution.

Low noise
The Denison Vane Technology allows very low noise levels over the entire operating range and during the whole life of the pump.

Versatility and compactness
With several displacements for the same installation size , the T7 are a very powerful and compact pumps. The various pumping units (cartridge kits) can also be combined with other pumping unit sizes in multiple pumps. This creates a wide range of multi flow pumps, very much adapted to the high power needs.

Applications:
• Injection Molding Machines
• Die casting
• Oil Press
