Polymer melt gear pump for plastic extruder
GM-ME series melt gear pump dedicated to thermoplastic extrusion process , such as sheet, plate, tube, film industry that requires special stable extrusion pressure flow system, installed on the extruder between exports and die head for metering pump.This series of melt pump adopts special gear structure and special flow design, to ensure the stability of the outlet pressure and flow rate .
The Features of this GM-ME series extrusion melt gear pump for plastic sheet extruder
(1)Minimal melt flow pressure pulsation , the melt flow can realize linear output ,suitable
(2)for precise extrusion system;
(3)This melt gear pump can be used on high temperature (350℃),high pressure(40Mpa),high viscosity (40,0 00Pa•s)xtrusion process
(4)Precise structure, high precision,long service life
Finished products show -melt gear pump
The main function of this extrusion melt gear pump
(1),Greatly improve the pressure stability of the extrusion die,improve the quality of the products
(2),The melt floow can realize linear output, easy to control
(3),Increase the extrusion output, improve the production output
(4),Decreasing the load, save energy and reduce the cost.
