...with direct feed solenoid pump

Principle

The solenoid operated direct feed pump feeds .04 cm² oil into each of the four lines leading to the lubrication points. (also .1 or .2 cm³ at choice) at every electric control impulse. By means of connected applying brushes the oil is transferred to the chain links.









Advantages

• Simple design
• Favourably priced as the system is composed of the pump, the tubes with applying brushes and the impulse generator only.
• Exact metering of the oil per shot, independent of temperature changes.
• Operating voltage 220 VAC (no three phase voltage required). No wearing parts in the pump.
• Easy adjustment of the lubrication frequency at the impulse generator.
• Tank with level switch on request.
• Monitoring of the solenoid pump action on request.
• With impulse monitor IP for supervising the oil quantity in the pressure line on request.

... with solenoid pump and progressive distributor

Principle

A solenoid operated pump force feeds .25 cm³ oil per stroke into a progressive distributor. Each of the four or more distributor outlets passes the oil in sequence to the lubrication points. The oil is transferred to the chain links by means of applying brushes.

Monitoring

A proximity switch assembled to the progressive distributor produces an electric signal per full cycle of the distributor.
The electric monitoring unit ESU supervises whether at least one signal per set time is produced. If there is no signal the unit gives a trouble warning.
The impulse is produced at an orderly function of the centralized lubrication system only. Therefore the trouble warning is given for the following faults:

• Low level of the oil in the tank.
• Faulty function of the solenoid pump or is control box.
• Faulty function of the progressive distributor.
• Rupture or damage of the oil tube between pump and progressive distributor.
