Alemite 7818-F4 Service Manual

Description
Model 7818-F5 is a double-post hoist (with
follower plate) designed to accommodate
pump assemblies (see Table 1) capable of
pumping medium- to heavy-weight material
from original 400-pound (180 kg) containers.
The air-operated power ram raises and
lowers the pump (not included) and follower
plate assembly. Pressure created from the
force on the follower plate causes the material
to enter the inlet of the pump.
Force and Pressure
The power ram develops a force of 1050
pounds (477 kg) on the follower when 100 psi
(6.9 Bars) of air pressure is applied to the
hoist. This translates into a pressure of 2.5 psi
on the material within a 400-pound container
(0.16 Bar for a 180 kg container).
Control Box
A pneumatic control box mounts to the left
column of the hoist. The operator positions
three separate valves to control the flow of air
to the hoist, pump's motor, and follower plate.
