Technical Specifications Overview
Marine and Offshore Applications
The CR-09-2P0-30-D-JA-J finds exceptional suitability in marine environments, where its specific configuration addresses the unique challenges of saltwater operation. The external drainage capability (denoted by the "D" in the model number) proves particularly valuable in marine applications, where it prevents case pressure buildup that could compromise seal integrity during temperature variations common in maritime operations. This feature allows for direct routing of leakage fluid to the reservoir, maintaining optimal internal pressure conditions and significantly enhancing reliability in a sector where maintenance opportunities may be limited by operational schedules.
On fishing vessels, this motor reliably powers deck machinery including winches, net haulers, and capstans. The compact flange mounting (2-type) facilitates installation in the confined spaces typical of vessel equipment rooms, while the standardized SAE O-ring port connections (specified by "2P0" in the model number) ensure leak-free performance despite vessel motion and vibration. For commercial shipping and offshore support vessels, the motor provides dependable power for auxiliary equipment such as mooring winches, hydraulic power packs, and specialized handling equipment, with the external drain system offering additional protection against the potential fluid contamination issues that can occur in marine hydraulic systems.
