OPERATION 

OPTIONAL RELIEF VALVE SETTING AND 
ADJUSTMENT 

The relief valve pressure setting/range is marked on a metal 
tag attached to the valve cover.  The relief valve should be 
set at 20 PSI (1.4 Bar) higher than the operating pressure or 
system pressure control valve, but no higher than the 
maximum working pressure of the pump.

 

 

Incorrect settings of the pressure relief 
valve can cause pump component 
failure, personal injury, and property 
damage.

 

 

Hazardous pressure 

can cause personal 

injury or property 

damage

 

 

 

 

Relief valve cap is exposed to pumpage 
and will contain some fluid. 

 

Hazardous or toxic 

fluids can cause 

serious injury.

 

 

 

 
 

DO NOT

 remove the R/V cap OR adjust the relief valve 

pressure setting while the pump is in operation. 

1. 

To INCREASE the pressure setting

, remove the relief 

valve cap (1) and O-ring (88).  Loosen the locknut (3).  
Turn the adjusting screw (2) 

inward

, or 

clockwise

.  

Inspect R/V cap O-rings and replace as required.  
Reattach R/V cap O-ring and RV cap. 

2. 

To DECREASE the pressure setting

, remove the relief 

valve cap (1) and O-ring (88).  Loosen the locknut (3).  
Turn the adjusting screw (2) 

outward,

 or 

counterclockwise

.  Inspect R/V cap O-rings and replace 

as required.  Reattach R/V cap O-ring and RV cap. 

Refer to the individual Blackmer pump parts lists for various 
spring pressure ranges.  Unless specified otherwise, pumps 
are supplied from the factory with the relief valve adjusted to 
the mid-point of the spring range. 

 
 
 
 
 
 

 
 

MAINTENANCE:  

 

 

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

 

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

 

Hazardous 

machinery can 

cause serious 

personal injury.

 

 

Hazardous pressure 

can cause personal 

injury or property 

damage 

 

 

 

 

 

 

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

 

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

 

Hazardous voltage. 

Can shock, burn or 

cause death. 

 

Hazardous or toxic 

fluids can cause 

serious injury. 

 

 

 

 

 

 

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

 

NOTICE: 

Maintenance shall be performed by qualified 
technicians only.  Follow the appropriate procedures 
and warnings as presented in this manual.
