FlexaDrive Marine

Logan FlexaDrive™ System:

The Logan FlexaDrive multiple pump drive system is a self-contained gearbox with integral flexible coupling, providing full engine power between your engine (power take-off) and transmission.

By incorporating a Logan Flexadrive and PTO, OEMs can achieve significant reductions in fuel consumption and emissions. This innovative approach not only extends the life of the driveline but also diminishes maintenance needs and downtime. The key lies in activating drives solely when necessary, streamlining operations and boosting efficiency.

Three (3) different models, offering from one (1) to two (2) pump towers, offer up to four (4) PTO/PTI pump pads with bi-directional rotation for engines ranging from 200 HP (150 kW) to 1500 HP (3700kW) at a maximum 2600 RPM.

Various step-up ratios are available for direct drive PTO’s, with standard ratios offered from 1:1 to 1:1.25.

Designed to Mount to Engine Flywheels:

Logan FlexaDrives are designed to mount directly to popular SAE flywheel housings, with typical sizes ranging from an SAE No. 3, No, 2, No. 1, up to a No. 0 size.

Optional Logan direct-drive PTO clutches offer on-demand engagement for hydraulic pumps, axial motors, electric drives, and other attachments, eliminating the need for continuous operation.

Incorporating a Logan FlexaDrive and PTO enables OEMs to significantly cut fuel use and emissions, extend driveline life, and reduce maintenance and downtime by activating drives only when needed, enhancing operations and efficiency.

FlexaDrive for Hybrid Tug Boat

As the name implies, Logan's FlexaDrive products are all about Flexibility. Our systems provide operators with the ability to configure their vessel's propulsion and power generation systems for maximum efficiency. Depending on operational requirements, main and auxiliary engines can provide either propulsive power, electrical power generation or both!

Marine Hybrid Drives

Marine hybrid systems use a diesel- or gas-powered combustion engine and an electric motor. Vessels can be driven entirely by the combustion engine or together with the electric motor to provide a boost of power –or driven by the electric motor in transit mode or in a lighter HP operation.

Logan Clutches and FlexaDrives act as connect-disconnect between the engine and auxiliary motor drive, engage drives only when required. Logan Clutches provide vessel designers the flexibility to meet zero-emissions targets while also providing the HP required to get the job done in marine applications.

Two-Position Pump Drive - 730 HP

The Logan 2-Position Pump Drive is outfitted for up to four (4) PTI/PTO pads, and can accommodate up to 730 HP / 544 kW Engines, with maximum speeds up to 2200 RPM. Total heads capacity of 300 HP / 225 kW. A single head has a maximum 160 HP/120 kW. Various step-up gear ratios are available for direct drive PTO's

FiFi Applications

Clutches for Fire Fighting Systems From 500 to 3000 HP

Logan LCT Clutches and Flexadrives for Fire Fighting Systems

Tug and Workboats utilize Logan LCT Series Clutches, Logan Direct Drive PTO Clutches, and FlexaDrives as a connect-disconnect between the diesel engine, fire pump, and auxiliary hydraulic pumps. Activation is simplified since Logan Clutches can be activated hydraulically or pneumatically. Remote engagement is possible from control panel or bridge.

FlexaDrive Hybrid for Tour Boats

SAE Direct Drive PTO Clutches

Logan Direct Drive Power Take-off (PTO) clutches are designed to mount between the main or auxiliary live PTO of your engine and attachment, i.e. auxiliary drive, single or multiple pump drive, hydraulic pump or attachment.

For example, Logan PTO’s are an effective and reliable solution for applications where hydraulic pumps are used on-demand, or in continuous, intermittent duty situations.
