The ball bearings used are sealed and lubricated, using a special lubricant for high temperatures (-40°C + 150°C). 

 

 

Defective bearings may reduce the Ex safety.

 

 

O-rings and similar parts 

During service/replacement, it must be ensured that the grooves for the O-rings as well as the seal faces have been cleaned before the 

new parts are fitted. 

 

 

Used rubber parts must not be reused. 

 

 

Explosion-proof pumps must be checked by an authorized Ex workshop once a year.

 

 

Oil change 

After 3000 operating hours or once a year, change the oil in the oil chamber as described below. 

If the shaft seal has been replaced, the oil must be changed. 

 

When loosening the screws of the oil chamber, note that pressure may have built up in the chamber. Do not remove 

the screws until the pressure has been fully relieved.

 

 

 

Draining of oil 

1.

 

Place the pump on a plane surface with one oil screw pointing downwards. 

2.

 

Place a suitable container (approx. 1 litre), for instance made of transparent plastic material, under the oil screw. 

 

Used oil must be disposed of in accordance with local regulations. 

 

3.

 

Remove the lower oil screw. 

4.

 

Remove the upper oil screw. If the pump has been in operation for a long period of time, if the oil is drained off shortly after the 

pump has been stopped, and if the oil is greyish white like milk, it contains water. If the oil contains more than 20 % water, it is 

an indication that the shaft seal is defective and must be replaced. If the shaft seal is not replaced, the motor will be damaged. If 

the quantity of oil is smaller than the quantity stated, the shaft seal is defective. 

5.

 

Clean the faces for the gaskets for oil screws. 

 

 

Filling with oil 

1.

 

 Rotate the pump so that one of the two oil holes in a vertical position facing upwards. 

 

 

 

 

           

 

2.

 

Pour the oil into the chamber. The suitable amount of oil is indicated by the second oil 

venting hole (positioned beside the vertical filling hole). Once the oil has reached and 

escapes from the hole at the side, the oil quantity is correct.  

3.

 

Fit the oil screws with new gaskets. 

 

The table shows the quantity of oil in the oil chamber of FKV and FKC pumps. Oil type: ESSO

8.2  Special maintenance  

Special maintenance operations must be carried out exclusively by an assistance workshop authorised by 

DAB Pumps.

  

 

8.3  Contaminated pumps 

 

If a pump has been used for a liquid which is injurious to health or toxic, the pump will be classified as 

contaminated. 

 

If you are asking to have a pump repaired, you must contact the service centre to give them the details about the pumped liquid, etc., 

before sending the pump for repair. Otherwise, the service centre may refuse to accept the pump. 

However, any application for service (no matter to whom it may be made) must include details about the pumped liquid if the pump has 

been used for liquids which are injurious to health or toxic. 

Before a pump is returned, it must be cleaned in the best possible way before it is returned.
