How to look at the size of the melt metering pump and how to calculate the output of the dosing pump?

 

The size of the melt metering pump can be expressed in terms of displacement.

 

That is, the gear of the melt metering pump. The volume discharged per revolution is generally expressed in cc. There are various metering pump
specifications such as 20cc, 31.5cc, 50cc, 100cc, 150cc, 200cc, and 250cc.

 

 

Melt metering pump

 

The melt metering pump rotates at 10~60r/min per minute. Due to the different viscosity of the conveyed material, the rotating speed can be adjusted.

 

The amount of material discharged by the melt metering pump can be multiplied by the density of the current material by the displacement multiplied by
the rotational speed of the melt metering pump per minute, which is the mass of the melt metering pump discharged per minute.

 

 

Melt dosing pump

 

For example: select a 100cc melt metering pump, when the material viscosity is 1000-5000pa.s, the melt metering pump speed range is 10~60 revolutions per minute.

 

When the rotational speed of the 100CC melt pump is 10 rpm, the output per minute is 100CC (transfer displacement)*10r/min=1000cc/min=1000ml/min,
and the output per hour is 100CC*10*60min=60000ml / H=60L/H.

 

When the rotational speed of the 100CC melt pump is 60 rpm, the output per minute is 100CC (transfer displacement)*60r/min=6000cc/min=6000ml/min,
and the output per hour is 100CC*60*60min=360,000ml /H=360L/H.
