Indroduction of the "continuous screen changer"
Continuous piston-type screen changers come in single- or multiple-piston styles and typically employ more than one breaker plate in the flow so that each breaker plate can be removed, one at a time, for screen changing without interrupting the flow. Piston units also include a venting/de-aeration process to ensure that no entrained air enters the flow and creates off-spec product.  And about the piston type continuous screen changer, we may have two kinds of this screen changer: single  pistion type continuous screen changer and double piston type continuous screen changer. and there are three kinds of different double piston screen changer 
1, with round breaker plate
2,with elongated breaker plate
3,with the screen wrapped on the pistons 
 


Here we main introduce the most common type GM-DP-R  series double piston continuous screen changer with round breaker plates.
 
Characteristics of  GM-DP-R series Continuous piston-type screen changers - double piston continuous screen changer with round breaker plates.
Two round  removable breaker plates on each bearing piston
"Continuous type" means operation of screen change without machine halt or disruption of melt flow.
Fit for almost all kinds of polymers
It works well under the high pressure 400bar(40Mpa) not impact the high performance.
The filtration screen area covers from 56cm² to 520cm², depending on the size, fit for output range from 30kg/h to 1800kg/h.

Applications
PP/PE water pipe extrusion machine
PPR gas pipe extrusion machine
Plate/sheet extrusion machine
Cast film extrusion machine
PET monofilament extrusion machine
PET strap extrusion machine
ABS recycling pelletizer
Masterbatch
