Preventative Maintenance
The operating conditions of your particular system
determine how often maintenance is required. Establish
a preventative maintenance schedule by recording
when and what kind of maintenance is needed, and
then determine a regular schedule for checking your
system.
DAILY:
Check hose for wear and damage, and inspect
fluid lines for leaks.
DAILY:
Check fluid drain/purge valve for proper
operation.
DAILY:
Check level of Throat Seal Liquid (TSL) in
displacement pump packing nut/wet cup. Fill nut 1/2 full
with TSL. Maintain TSL level to help prevent material
buildup on piston rod and premature wear of packings
and pump corrosion.
Corrosion Protection
Always flush the pump before the fluid dries on the
displacement rod. First, flush with water, then with oil.
Relieve the pressure, but leave the oil in the pump to
protect the parts from corrosion.
NOTICE
Exposing the motor and/or control to water can cause
damage and possible motor failure. Do not store the
pump outside. Do not spray water directly into the
motor fan.
NOTICE
To prevent rust, never leave water or water-based fluid
in the pump overnight.
NOTICE
Material left on the throat seal can dry out and damage
the seal. Always stop the pump at the bottom of the
stroke to avoid damage to the throat seal.
