7. OPERATING INSTRUCTIONS 

 
7.1 MEASURES TO BE TAKEN PRIOR TO START-UP

 

 

The unit may be put into operation by specialized personnel. 

 

Using the pump submerged in fluids or in a particularly aggressive or explosive/flammable environment is prohibited 
unless it has been prepared ahead of time by the supplier for this purpose. 

 

Use gloves and eye protection as required by the lubricant safety data sheet. 

 

DO NOT use lubricants that are aggressive to NBR gaskets. If you are unsure, contact the Dropsa S.p.A technical office 
for a detailed list of recommended lubricants. 

 

Never ignore health hazards and always follow sanitary regulations. 

 

Always use suitable piping for the operating pressure. 

 

Check the integrity of the pump; 

 

Check  the  lubricant  level  in  the  reservoir  (min/max  indication  on  the  reservoir),  in  case  of  low  level,  proceed  as 
described in Section 

7.3 Filling the reservoir

 

Ensure that the pump operates at operating temperature and that the pipelines are free of any air bubbles; 

 

Check the correct connection of electrical devices.

 

To determine the maximum operating pressure, it is necessary to know the pressure drop of the pipeline connected to the 
pumping elements. 
As an example, the following diagram shows the pressure drop of the delivery pipeline flow by unit length depending on 
the  operating  temperature  and  for  a  particular  type  of  lubricant  (in  this  case  NLGI  00  grease  with  160cSt  base  oil  and 
NLGI2 grease with a 180 cSt base oil)

 

Depending on these variables to achieve a proper supply to the delivery point, it is always necessary to ensure that the 
pipeline pressure loss plus the pressure required at the lubrication point does not exceed the maximum pressure supplied 
for pump delivery.

 

The maximum pressures corresponding to the delivery point of the pumping element, taking into consideration the most 
severe operating conditions are as follows, taking the toughest operating conditions into consideration: 

 

1÷12  pumping elements =  80 bar (1160 psi) 

13÷24  pumping elements =  50 bar (725 psi) 

25÷36  pumping elements =  35 bar (507 psi)
