PRIMING
Priming consists of pumping a lubricant to coat the s-tube and delivery lines
to assist the initial concrete material in getting through the delivery lines and
avoid blockages. Once the delivery lines are full of concrete, that material
will supply the lubrication necessary for the material to flow through the
delivery lines. However, it is imperative that a primer be used ahead of the
initial concrete material to pre-lubricate the lines in order to avoid blockages.
A suggested grout to use for priming and lubrication may consist of 2 parts
sand and 1-part cement and mixed to a consistency of a thick cream.
The amount of grout required depends on the length of the delivery line as
well as the material being pumped. Operator experience will eventually
indicate the amount to be required.
In addition to grout, there is a wide variety of priming products available on
the market.
