Pump Hoist Model 7818-F5

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.
