Single-line lubrication system 603 S / 653 S with QSL / SL lubricant metering devices - SKF Lubrication Systems Germany GmbH


Wind Industry Profile of

Single-line lubrication system 603 S / 653 S with QSL / SL lubricant metering devices

To be combined with SE 1 suction elements for the extraction of used lubricant from a single-line system and PU lubrication pinion for the even mechanical lubrication of open gear drives.


• For rotating operation

QSL/ SL metering devices suitable for high pressure - with new corrosion protection

• For fast separating lubricants


Equipment that operates in harsh conditions requires regular lubrication to ensure performance. When a bearing or component fails as a result of insufficient lubrication the result is downtime and losses. The single-line 603S and 653S pumps/systems automatically supply the lubrication points with exact metered quantities in programmed interval while the equipment is in operation. As a result, the robust system is ideally suited for wind turbines – even offshore applications.


System elements
Pump and accessories – all-in-one

The pump with integrated controller is easy to program. The all-in-one design of the pump includes the programmable controller, a pressure switch/transducer and a vent valve.


PU (Polyurethane) lubrication pinion
for the mechanical lubrication of open gear drives. The PU pinion has a special surface to ensure an even 100% lubricant film. Read more under PU Pinion


SE1 suction element
for the e
xtraction of used lubricant from a single-line system

- with new corrosion protection

The SE1 suction element was especially developed to extract the used lubricant from single-line systems used in wind turbines. The used lubricant is collected in a separate 10 liter container AFB 10 and can be recycled – or used for example for the lubrication of gear drives.

QSL and SL lubricant metering devices - with new corrosion protection
The metal-to-metal fit of the injectors makes them suitable for high pressure. Each injector’s output can be individually set. The injector function is generally visually monitored, but optional electrical monitoring or a GSM controlled system is available.


Simple system design - easy to expand
The single-line system’s design and layout is uncomplicated, making it easy to install and operate. A single mainline reduces material and installation costs.


Easy to service
It is quick and easy to exchange out an injector. The mainline or neighboring injectors do not have to be removed. The exchange can be performed between lubrication cycles so that there is no wastage of lubricant or excessive costly downtime.


Visual monitoring – to ensure all is well
Each injector has an indicator pin that moves with the pressure buildup and venting. This facilitates easy trouble-shooting when required by simply observing the indicator pins.


Additional pressure switch
An additional pressure switch at the end of larger systems can be used for added pressure control to ensure correct lubrication.
