Fan Drive System Variations

Gear pump/gear motor with EC

Open circuit piston pump/gear motor with EC

Reversible piston pump/gear motor with EC

Multiple function reversal piston pump/gear motor with EC

Based on your needs, we can design a number of different fan drive systems. Configurations all involve the use of PLUS+1™ microcontrollers for precise and efficient control. Typically we employ one of the following combinations of pumps and motors for hydraulic systems.

• Gear pump/gear motor/with, or without, reversing manifold
• Piston pump/gear motor/with, or without, reversing manifold
• Piston pump/piston motor/with, or without, reversing manifold

Use of Series 45 variable piston pumps improves fan drive system efficiency over gear pumps. In addition, use of a PLUS+1 microcontroller and a manifold to reverse the fan motor allows grass clippings or other light debris to be blown out of the radiator.
