the protective plugs immediately before installing the supply pipe to the pump.
Keep the protective plugs for reuse during any future disassembly.
▪
Be careful when transporting and assembling the pump / pump aggregate.
▪
Before the pump / pump aggregate is installed into the installation / machine,
ensure that all parts that contact the product ahead of the pump (such as
tanks, pipes, valves) are carefully cleaned. Contamination, metal particles,
etc. lead to pump damage.
▪
Do not start-up the pump in dry state. If required, use a lubricant (such as
fluid mineral oil) to manually rotate the pump before installing the pump into
the installation / machine. Upon delivery, Barmag pumps are already equipped
with a lubricating medium. While in operation, the pump is lubricated by the
pump medium.
▪
In order to avoid that spin finish
emerges from the nozzles at a
pump standstill, the nozzles should
always be higher than the liquid
level in the container.
We do recommend to keep the dif-
ferential pressure between the
pump's suction and pressure side
als small as possible. To this pur-
pose, the spin-finish nozzles should
be located max. 500 mm above the
liquid level in the container (dimen-
sion “X”). The pump's intake height
should be approx. 500 mm (dimen-
sion “Y”).
The installation location of intake
and outlet can be either at the side
or on the top, however, preferential
is the top installation.
▪
Within one line, hoses of the same length and with the same inner diameter
should be installed between the pump outlets and the spin-finish nozzles. In
order to avoid the formation of air bubbles, the hoses from the pump to the
nozzles are to be installed with constant rise. Hoses must not be bent or
pinched.
▪
Filtering of spin finish before inflow into the pump is essential for troublefree
operation and for protection of the pumps. Recommended filter fineness ap-
prox. 25 μm or finer.
