8.  Operation 

 

WARNING 

 Danger of burns from hot pump parts or hot medium 

 

During or after operation of the pump, some pump 
parts may be hot. 

 

  Allow the pump to cool after operation. 

  Take safety precautions against the contact of 

hot parts/media. 

 

 

WARNING 

 Injury of the eyes 

 

During excessive approach to the inlet or outlet of 
the pump, the eyes could be injured by the upcoming 
vacuum or overpressure. 

 

  Don’t look into the pump’s inlet or outlet during 

the operation. 

 

  Only operate the pumps under the operating parameters and 

conditions described in Chapter 4. Technical Data. 

  Make sure the pumps are used properly (see Chapter 2.1). 

  Make sure the pumps are not used improperly (see Chapter 

2.2). 

  Observe the safety precautions (see Chapter 3). 

  The pumps are intended for installation. Before putting them 

into service it must be established that machinery or equipment 
in which they are installed meets the relevant regulations. 

 

WARNING 

 Hazard of the pump head bursting due to excessive 

pressure increase 

 

  Do not exceed max. permissible operating pres-

sure (see Chapter 4. Technical Data. 

  Monitor pressure during operation. 

  If the pressure exceeds the maximum permissi-

ble operating pressure, immediately switch off 
pump and eliminate fault (see Chapter 10. Trou-
bleshooting).
 

  Only throttle or regulate the air or gas quantity in 

the suction line to prevent the maximum permis-
sible operating pressure from being exceeded. 

  If the air or gas quantity in the pressure line is 

throttled or regulated, make sure that the maxi-
mum permissible operating pressure is not ex-
ceeded. 

  Ensure that the pump outlet is not closed or con-

stricted.
