With the thread adapter made of high-quality stainless steel 1.4301 (304) a pump, a drain cock or any other connection with thread G 2" (Whitworth pipe thread) can be screwed onto a container with G 1 1/2" thread. The thread adapter adapts and thus compensates for different thread shapes. The drum adapter ensures that decanting is liquid-tight; a seal made of ePTFE reliably seals the connection. The thread adapter made of stainless steel is electrically conductive and highly chemically resistant. It can therefore be used for filling solvents and other flammable liquids (e.g. alcohols, petrol, diesel etc.) as well as for weak alkalis and acids.

PP barrel pump with rigid discharge tube. Barrel pumps made of polypropylene allow a fast transfer of liquids from barrels, canisters and tanks. The good chemical resistance of PP allows acids, alkalis and aggressive detergents to be transferred. The low-mounted non-return valve of the barrel pump and the immersion depth that can be steplessly adjusted using the barrel screw joints ensure good removal of residual liquid. The barrel screw joint fastens the barrel's pump securely to the barrel. Barrel screw joints and thread adapters for commercially available containers are available as optional accessories.

Heating bands are the ideal solution for the heating of tubes an cylinders. Mica band heaters, frequently used as nozzle heaters, are made with a plastic-tight stainless steel casing. Such mica heating bands are in many dimension available from stock. The Ceramic heating band type is suitable specially for applications with high watt density and therefore for higher temperatures. Ceramic band heaters, also known as ceramic ring heaters or cylindrical ceramic sectional heaters, are attached to the contact surface by means of a clamping mechanism. A preferred field of use for ceramic band heaters is the heating of plasticising cylinders, bushings and nozzles of injection moulding machines and screw barrels of extrusion machines. For thermal optimization and process control ceramic band heaters can also be offered with insulation jackets or air cooling.

Extruder machine is used for melting, mixing plastic material. Masfen produces specific screw and barrel for material type, that provides perfect mixing and homogeneous. Our Extruders has 50kg/h to 1000kg/h capacity for PE,PEX,PP,PPRC type plastics.
