clean oil to the pump
Clean oil delivered to the
system under pressure.
Pressure adjustable between
15 and 100 PSI
If system pressure equals spring pressure the
pump will not move. The pump will only move
a small amount as spring pressure tops up oil
pressure when oil is delivered to the chains.
Unique fixed piston design.
Cylinder moves over piston to
create pressure.
Cam adjusts to alter spring pressure.
Spring pressure governs oil pressure in
the system.
More pressure
delivers more oil
to chains.
