The SEIM PCX-WTG series Twin Screw Pump is ideal for pumping asphalt. It has a longer service life, resulting in no damage from pumping higher viscosities or slugs of cold asphalt. The pump is self priming, has dry run capabilities, and will empty both suction and discharge piping. The PCX-WTG has higher efficiency by using less energy, has a smaller motor and no gearbox, and runs at a direct motor speed. The pump is ideal due to it's cartridge design, and it's internal components can be replaced quickly and easily without disturbing the piping. the PCX-WTG twin screw pump has only one shaft seal and bearing, and is easily serviced. You can choose form many seal options. The fully jacketed pump casing and seal chamber reduces maintenance costs over time. You can also choose an optional built-in safety pressure relief valve. The pump is well balanced, easier to adjust, and has less leakage. Choose the PCX-WTG in cast iron, welded steel, or stainless steel case.
