Rotary dosing system

Grease rotationally symmetrical products intelligently

Rotary dosing system for industrial, technical lubricants

The SOMA RDS (Rotary Dosing System) enables rotationally symmetrical products to be greased intelligently: programmable, volumetric and contactless.

Rotationally symmetrical components form the key elements of many products and are therefore used in virtually all areas of industry. Wear produced by friction can be seen in many applications involving rotationally symmetrical components and can be significantly reduced by using a defined volume of appropriate lubricant in a specific location.

The SOMA RDS rotary dosing system offers maximum flexibility in fully automatic lubricant dosing for rotationally symmetrical products - configurable, volumetric and contactless. Based on the proven SOMA IDV impulse dosing valve and a hollow-shaft stepper motor, the SOMA-RDS rotary dosing system showcases its benefits in this area.

Any number of dosing points across 360° are freely programmable. Optional full monitoring with the SOMA DIS dosing inspection system.

Advantages of the rotary dosing system

Infinitely adjustable, reproducible constant dosing volume
Angular accuracy, non-contact dosing
Process reliability thanks to integrated dosing piston stroke query
Simple integration thanks to the motor controller supplied
Valve heating with temperature controller for improving the dosing capability of viscous lubricants including
option to have circumferential dosing on the inner and outer diameter using specific dosing nozzles
Optional expansion with SOMA DIS dosing inspection system for full monitoring

Areas of application

Sometimes it is not possible to lift out a component and turn it in front of the nozzle because of the cycle time and design factors. With the RDS, any number of dosing points can be freely programmed across 360°. Greasing is also possible from the inside and outside.

Rotationally symmetrical components, circular segments that need to be greased
Cylinder greasing, internal and external greasing
Greasing gears with angular precision

Technical data – Rotary dosing system

An overview of the most important technical data for the SOMA rotary dosing system.

Technical data	RDS
Dimensions (L x W x H):	250 mm x 80 mm x 100 mm
Medium inlet pressure:	Pmax = 0.5 - 12 bar
Compressed air supply:	P = 3 - 6 bar
Dosing volume:	V = 1 - 45 mm³/dosing pulse *
Dosing frequency (fmax):	20 Hz
Voltage supply:	230V AC, 50 - 60 Hz

* For speeds faster than 3.5 seconds/revolution, a 10 kHz pulse direction terminal is required. A motor controller is included for installation in your control cabinet. A higher-level control system performs the activation.
