MAINTENANCE 

 

 

 

Hazardous 

machinery can 

cause serious 

personal injury.

 

Failure to disconnect and lockout 
electrical power or engine drive before 
attempting maintenance can cause 
severe personal injury or death 

 

Hazardous voltage. 

Can shock, burn or 

cause death.

 

Failure to disconnect and lockout 
electrical power before attempting 
maintenance can cause shock, burns or 
death 

 

 

 

 

 

 

 

 

 

Hazardous pressure 

can cause serious 

personal injury or 
property damage

 

Disconnecting fluid or pressure 
containment components during pump 
operation can cause serious personal 
injury or property damage.

 

 

Hazardous pressure 

can cause serious 

personal injury or 

property damage

 

Failure to relieve system pressure prior 
to performing pump service can cause 
serious personal injury or property 
damage.

  

Systems with meters will still 

be pressurized even after the hose is 
emptied

 

 

 

 

 

 

 

 

 

 

 

Hazardous or toxic 

fluids can cause 

serious injury. 

If pumping hazardous or toxic fluids, 
system must be flushed and 
decontaminated, inside and out, prior 
to performing service or maintenance 

 

Hazardous 

machinery can cause 

severe personal 

injury or property 

damage.

Failure to set the vehicle emergency 
brake and chock wheels before 
performing service can cause severe 
personal injury or property damage.

 

 

 

 

 

 

NOTICE: 

Maintenance shall be performed by qualified technicians only.   

Following the appropriate procedures and warnings as presented in this manual. 

 

SCHEDULED MAINTENANCE 

STRAINERS 

Strainers must be cleaned regularly to avoid pump starvation.  
Schedule will depend upon the application and conditions. 

LUBRICATION 

NOTICE: 

To avoid possible entanglement in moving parts do not 
lubricate pump bearings, gear reducer or any other parts 
while the pump is running. 

Pump bearings should be lubricated every one to twelve 
weeks (AT MINIMUM), depending on the application, and 
operating conditions. 

Recommended Grease: 

Dow Corning

® -

 MOLYKOTE 44 

DuPont

® - 

KRYTOX GPL 203  

 
 
Greasing Procedure: 

1.  Remove the grease relief fittings (76A) from the bearing 

covers (27A).  

2. 

SLOWLY 

apply grease with a hand gun until grease 

begins to escape from the grease relief fitting port. (76)  

3.  Replace the grease relief fittings (76A). 

DO NOT overgrease pump bearings. While it is normal for 
some grease to escape from the grease tell-tale hole after 
lubrication, excessive grease on pumps equipped with 
mechanical seals can cause seal failure. 

IF EQUIPPED: Blackmer gear reducers are shipped from the 
factory without oil in the gearcase. Fill with the grade of oil 
indicated on the reducer tag. The oil should be changed after 
the first 48 hours of use and approximately every 500 hours of 
use thereafter.
