The glue feed units with piston pump are especially indicated to supply medium viscosity glues, adhesives and fluids. They are equipped with pneumatic piston pump 5:1 ratio. The piston pump can be installed on wall mount bracket(optional) or stand on wheels (optional). The bucket containing fluid is connected to the piston pump through a flexible reinforced tube. The inspection and replenishment of the bucket is facilitated by a hinged flap door on the bucket lid.
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 inlet 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 5:1 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 5:1 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.
