USE 

 

3.1 

Putting into service 

 

♦ 

It is advisable to operate the pump while filling to facilitate the distribution of grease through the pumping area 
and to avoid the formation of air bubbles.

 

♦ 

The unit should be opened and repaired ONLY by qualified personnel.

 

♦ 

The pump MUST NOT be submersed in fluids or utilised in environments which are particularly aggressive or 
explosive/inflammable if not prepared for this purpose beforehand by the supplier.

 

♦ 

Use gloves and safety glasses as required in the lubrication oil safety chart. 

♦ 

DO NOT use aggressive lubricants with NBR gaskets and seals; if in doubt consult the Engineering 
Department of Dropsa SpA, who will provide a chart with the details of recommended oils 

♦ 

DO NOT ignore dangers to health and observe all hygiene standards. 

 

Action to be taken prior to start up 
 

♦ 

Verify the integrity of the pump; 

♦ 

Fill the tank with suitable lubricant; 

♦ 

Verify that the pump is at operating temperature and the tubing free from air bubbles; 

♦ 

Check that the electrical connections have been effected correctly; 

♦ 

On starting the pump, check the direction of rotation of the electric motor: If rotating in the wrong 
direction invert the cable connections. 

☞ 

WARNING 

For grease pumps it is essential that the paddle rotates in the direction of the arrow shown on the plate on 
the tank (anticlockwise). Where the direction is incorrect, invert the two electrical power cables to the 
motor. 

 

3.2 Use 

 

1.  Verify the starting of the pump; 
2.  Check the rotation of the paddle (only for grease pumps); 
3.  Verify the adequate lubrication of the machine (if doubt exists as to the correct functioning consult the 

Engineering Department of Dropsa SpA to request test procedures). 

 

3.3 

Transport and storage 

 
Transport and storage is effected in a cardboard package. 
No particular precautions are required except as noted on the package itself. 
 
Handling can be effected manually.  

!

  

Lift the unit with taking account of the right way up indicated on the cardboard carton 

!

     

The machine components can withstand temperatures, during storage, from -20 to +50°C; however, in 
order to avoid damage, starting of the machine should occur at a minimum temperature of -5°C.
