The glue feed units with diaphragm pump are particularly indicated to supply low viscosity glues, adhesives and fluids.
They are equipped with double diaphragm pneumatic pump 1:1 ratio and anti-stall pneumatic control valve. The pump is assembled on a easily removable plastic bucket lid that simplifies the operations to replace the empty bucket with a full bucket, or also to maintenance and clean the pump.
The pump can be transfered on a full bucket containing water for the washing operations of the plant. The pump has a bottom valve to prevent the fluid comes out by the suction pipe during the operations of replacing the empty bucket. The glue feed units are equipped with a stainless stell glue filter placed on the intake tube of the pump. It makes a first filtering of the fluid, preventing the aspiration of any possible lumps.
Some versions are assembled with a fine mesh stainless steel filter which has the double function to drop the pulsations of the pump and filter any possible impurities contained into the aspirated fluid.
To control outlet pressure, therefore the glue quantity supplied, it can be assembled with a 1:1 manual stainless steel pressure regulator. Alternatively, if you need to check the pressure in relation to the speed of the machine where the glue feel unit is installed on, is possible to assemble a 1:1 automatic stainless steel pressure regulator controlled by a proportional valve.
A level control float (optional) can be assembled to indicate the minimum fluid level into the bucket.
