Pumping grease
The biggest problem that grease poses to pumping is that it will
not readily flow into the pump inlet. Our bare pumps overcome this
by using a piston with a priming plate that pulls the grease into
the inlet. However, flow rates are very low.
Flow rates can be increased and/or higher viscosity materials pumped
from standard drums and pails by using special equipment:-
- An elevator assembly can be used. The weight of the pump
acts on a follower plate that levels the grease and forces it
into the pump inlet. The follower plate also 'wipes' the side
of the drum or pail, thereby reducing material loss. The elevator
is then used to raise the pump and the follower plate when replacing
empty drums or pails.
- A single post or a twin post ram assembly is a more powerful
device. The air driven ram acts on a ram plate driving the grease
into the pump inlet in a similar way to the follower plate mentioned
above, but more forcefully. This equipment also eases the changing
of drums or pails.
Graco lube pumps that are specifically designed for grease
We can offer an extensive range of pumps beginning with the medium
pressure 10:1 ratio President and 15:1 Fire-Bail. We also have 50:1
and 75:1 ratio Fire-Ball pumps and 50:1 ratio President pumps for
high pressure dispense applications.
Pump packages
Most of the above pumps are available in 'off-the-shelf packages
that combine a pump with a drum cover or a portable cart or an elevator.
Complete ram assemblies with pumps from the much larger Bulldog
and King pump range can be used in the most arduous of applications.
