ABSTRACT:
A piston pump has a piston and cylinder. A gas is supplied into the cylinder during and/or after a suction stroke of the piston pump, and a high-viscosity material is supplied into the cylinder after the suction stroke. A discharge stroke of the piston pump is effected after completion of supply of the high-viscosity material to thereby discharge the gas and high-viscosity material into a pipe. Use is made of piston pumps45A and45B, each including a cylinder and a piston which reciprocally moves within the cylinder to effect the suction stroke and discharge stroke, and a membrane gas generator10to which compressed air is supplied to generate a gas. A low-pressure gas generated by the membrane gas generator10is supplied into each piston pump and the high-viscosity material is introduced into the gas.
