    摘要: A pumping device for spacer material, such as TPS (Thermoplastic Spacer) material for insulated glazing units (IGUs). The pumping device includes a pumping unit driven by a control signal, including a cylinder driven by the control signal, a rod reciprocating at regular intervals by the operation of the cylinder, a piston installed at an end of the rod and reciprocating synchronously with the rod to pump spacer material in the drum in predetermined amounts, a through-hole formed for the passage of the piston and rod, a pressure plate sealingly pressing the spacer material in the drum and surrounding the rod, and a pumping housing sealingly enclosing the rod. The pressure plate includes multiple suction holes formed for the passage of spacer material in the drum, and these suction holes communicate with the through-hole.
