SAFETY
Read and carefully observe these operating instruction
before operating the pump. The pump must be operated,
maintained and repaired exclusively by persons familiar
with the operating instructions. Operate the pump only after
Safety instructions and this Operation Manual are fully
understood.

GLAND PACKING DESIGN*
Many industrial type materials (sealants, adhesives, inks,
etc.) display a tendency to dry out and to build up on the
pump plunger rod. These hard dried out materials cause
the gland packing to wear rapidly, resulting in leakage and
ultimate pump failure The second problem is the gland seal
exposure to high pressure and in particular, to pressure
fluctuation during pump operation (stroke change over).
The gland packing design* of Pile Driver III pumps address-
es both problems:
Externally, a special spring type Metal wiper (Item 5) scrapes
built-up and dried material from the pump plunger before it
is pulled through the gland packing on the down stroke. In
order to help the metal wiper work longer and more efficient-
ly, the lube well of the pump should be filled with a fluid
compatible with the material being pumped.
Do not fill the lube well to full capacity, as the reciprocat-
ing movement of the pump may draw fluid into the
airmotor.
Internally, a special Protection Sleeve (Item 9) with
concentric grooves creates a labyrinth path which reduces
the effects of internal pressure and stroke change over
fluctuation on the gland seal. In addition, a second internal
wiper limits gland seal exposure to the pumped material.
The combination of the metal wipers and the protection
sleeve results in longer gland seal life and prevents
leakage.
