Advantages of Hansen P4 Horizontal Series
Dedicated Horizontal Housing
Stepped housing, better load distribution & easy access to mounting feet
Split Housing & Large Inspection Cover
Maintenance-friendly, easy inspection without oil drainage
Powerfull Gear Geometry
For maximum load capacity, minimum losses & lower noise levels
Maintenance-Free Sealing Systems
Oil-lock at the high speed shaft designed to keep the oil in and dirt out
Never a Dry Start-up
Centralized oil filling guarantees initial oil lubrication at start-up. During operation, optimized splash lubrication with oil flow through the bearings

What are backstops?
Backstops are safety devices and have to be inspected at regular time intervals. The periodical inspection is to be carried out by authorized personnel. The frequency of the inspection depends on the type of application. Please refer to the P4 service manual for recommended inspection intervals
What type of lubrication method does the P4 use?
Hansen P4 units use one of the following systems:
- Splash Lubrication (standard with horizontal shaft gear units for speeds between 750 and 1800RPM at the high speed shaft. Gears and output shaft bearings are lubricated by immersion in the oil bath. Oil splash from gears fill the oil pockets in the housing, assuring gravity circulation lubrication of the bearings via channels in the housing and covers.)
- Force Feed Lubrication (all rotating elements above oil bath level are lubricated by a gear pump forcing the oil through pressure lines. Forced feed lubrication is available as circulation lubrication or pressure lubrication.
