Customer: Siberian Chemical Combine
The metering pumps make part of the TUE Re-Extraction Area of the Fabrication/Recycling Facility of the Pilot Demonstration Energy Complex (PDEK) at the Siberian Chemical Combine.
The main purpose of the pumps is to meter and pump reactant and process solutions. A hydraulic cylinder and a plunger are the main elements of the pump. The operating principle of the metering pump is based on switching from underepressure to overpressure in the pumping chamber at regular intervals. The plunger motions are rotational and at the same time reciprocating because of the profiled cam and the magnetic coupling.
A frequency converter of the pump motor regulates the slurry flow by the rotating and reciprocating motion frequency of the plunger.
