MAINTENANCE

 

Failure to disconnect and lockout 

electrical power or engine drive before 

attempting maintenance can cause 

severe personal injury or death 

Hazardous 

machinery can 

cause serious 

personal injury.

 

 

 

 

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 

 

 

 

If pumping hazardous or toxic fluids, 

system must be flushed and 

decontaminated, inside and out, prior to 

performing service or maintenance 

 

Hazardous or toxic 

fluids can cause 

serious injury. 

 

 

 

 

 

Failure to disconnect and lockout 

electrical power before attempting 

maintenance can cause shock, burns or 

death 

Hazardous voltage. 

Can shock, burn or 

cause death.

 

 

 

 

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 pressure 

can cause serious 

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.

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,  hydraulic  adapter  coupling  or 

any other parts while pump is running 

NOTICE: 

If pumps are repainted in the field, ensure that the grease 

relief fittings (76A) are functioning properly after painting.  

Do  NOT  paint  them  closed.    Remove  any  excess  paint 

from the fittings. 

Pump bearings and hydraulic motor couplings (if equipped) 

must be lubricated every three months at a minimum. More 

frequent lubrication may be required, depending on the 

application and the operating conditions. 

Recommended Grease: 

Mobil® - Mobilgrease XHP222, 

Exxon® - Ronnex MP Grease 

or equivalent Lithium grease. 

 

Greasing Procedure: 

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

covers (27) or hydraulic motor adapter (135). 

2.  SLOWLY apply grease with a hand gun until grease 

begins to escape from the grease relief fitting port. Discard 

excess grease in accordance with the proper codes and 

regulations. 

3.  Replace the grease relief fittings (76A). 
DO NOT over grease pump bearings. While it is normal for 

some grease to escape from the grease tell-tale hole after 

lubrication, excessive grease can cause mechanical seal 

failure. The tell-tale hole is located in the head (20) between 

the bearing (24) and the mechanical seal (153).
