Roesen Box Lubricator model HD
Roesen Box Lubricator model HD enables the indi- vidual adjustment and verification of oil flow to each lubrication point, also in operation. Due to a modular design and “Pump-to-Point” of the Roesen Box Lubricator HD we can customize to a large variety of plants and drive systems. Because of the forced control of conveyor and metering piston a Roesen Box Lubricator is ensured to run up safely – also after a longer downtime.
The wide product portfolio of Roesen Box Lubrica- tors HD provides gas free lubrication flow to up to 32 lubrication points with individually adjustable feed rates up to 0,23in 3 /min per lubrication point and with working pressures up to 10850psi. All oils and emulsions with a viscosity range from 25 to 3000 cSt – also food grade oils – are usable.

Roesen Box Lubricator HD functioncalibration. The control basin (c) feeds the pressure piston (57) with oil which is provided by the piston valve (65) and the check valve (56) to the lubrication line. The flow rate is adjusted by the regulation scew (64) which is secured against unintentional misad- justment by means of a lock spring (61). The camshaft (28) drives the conducting piston (59) with the pressure piston (57) and the allocation piston (60) by means of the fork (58). The control piston (61) follows the suction stroke of the allocation piston (60) until it reaches the adjustable stop, which is provided by the carrier (62). Depending on the position of the regulation screw (64) a larger or smaller vacuum develops between the allocation pisten (60) and control piston (61) which sucks up oil through channel (a) into the chamber of the allocation piston (60). While the compression stroke closes the channel (a), the oil is pumped through channel (b) to the visual flow control (49) where it visibly returns to the control basin (c) of each lubrication outlet and is accessible for flow calibration. The control basin (c) feeds the pressure piston (57) with oil which is provided by the piston valve (65) and the check valve (56) to the lubrication line. The flow rate is adjusted by the regulation scew (64) which is secured against unintentional misad- justment by means of a lock spring (61).

Model HD drive versions
Transmission driveThe transmission can be adapted to customer needs with different gear ratings. The drive shaft can be fitted with different adapters and diameters. The input shaft can be placed up- / downwards, front- / backwards or to the side. The transmission can be mounted on the left- or righthand-side of the lubrication box. This makes it possible to drive the system by chain, gearwheel, coupling or a belt.
Motor- / Transmission driveA matching electric drive with an adaptable mounting position can be configured to confined spaces. The motor can be delivered with one- or three-phase power connection. Special versions support the adjustment of variable engine speeds.
Technical realization conform to ATEX directives are available.
Oscillating swingarm driveThe oscillating swing arm is used to drive the lubrication pump for an alternating drive and can be moun- ted on the left- or right-hand-side. This is used for example for stuffing lubrication on plunger plumps.
Model HD optional equipment
• All available versions (transmission-, motor- or oscillating swing arm)
can be fitted with a hand driven
• Pump outlets are delivered with 6mm, 8mm, 1/4” solderable or compression fitting. Roesen
• All pump outlets will be fitted with high quality check valves for maximum operational security.
• Furthermore all outlets can be equipped with oil returning pressure relief valves.
• Function monitoring can be provided by our optional built in Flow-Switch
Roesen HD compact oiler
This design is very compact and suitable for confined space conditions. The lubrication reservoir can be adapted in size and layout to your needs, includes the lubrication elements and is delivered as an entire unit. Optional components are optical and electrical temperature- and fill level monitoring devices as well as a heating system.
Roesen HD Standalone-SystemWe offer centralized lubrication units as Stand-Alone systems. The main elements of this system are the Roesen Box Lubricators HD II to HD IV. A combination of Roesen models HD and EZ are possible. The lubricant reservoir will be customized in size and layout to your needs and provided with the right lubrication system as a whole unit. Supply of lubrication from the reservoir is provided by gravitation. Optional components are optical and electrical temperature- and fill level monitoring devices as well as a heating system. On request we will provide you with a redundant lubrication unit. Our pump systems are configured by default for reliable “Pump-To-Point” lubrication. If desired the system can be adapted to a Progressive Divider or Divider Block system.
