Neat Polymer Supply Line
This line connects the source of the neat polymer to the Pulsafeeder Polymer Makedown System.
Please refer to Figure 1 on page 6. The neat polymer source must be located above the centerline of
the pump (flooded suction condition); ensure that the suction line has a gradual downward slope from
the tank to the skid suction connection. The purpose of this is to prevent air pocket(s) in the suction
line which could affect proper operation of the pump. Include whatever provisions you consider
necessary to facilitate maintenance and operation such as isolation valve(s), drain and/or flush
connections, etc., making sure that this sub-system enables SAFE OPERATION.
Discharge Line
This line connects the Pulsafeeder Polymer Makedown System to your served process. Please refer to
Figure 1 on page 6. If the injection point is below the dosing chemical source or if injecting into a low
pressure area such as the suction of a pump, an anti-siphon/ back pressure valve should be located as
close as possible to the injection point to prevent unwanted chemical feeding. Include whatever
provisions you consider necessary to facilitate maintenance and operation such as isolation valve(s),
drain and/or flush connections, etc., making sure that this sub-system enables SAFE OPERATION.
Electrical Connection
The control panel is provided with a standard plug for connection to 115V (+/-10%) , 20A power to
operate.
