11. ANUAL Moyno 2000 CC Pumps 1 1 INTRODUCTION 1 2 General The Moyno 2000 pump is a progressing cavity pump A single helical rotor rolling eccentrically in the double threaded helix of the stator creates the pumping action In its revolution the rotor forms in conjunction with the stator a series of sealed cavities 180 degrees apart As the rotor turns the cavities progress from the suction to the discharge As one cavity diminishes the opposing cavity increases at exactly the same rate Thus the sum of the two discharges is a constant volume The result is a pulsationless positive displacement flow 1 3 Scope This service manual covers the installation and maintenance requirements for standard close coupled configuration of the Moyno 2000 pump line Disassembly and assembly procedures are also covered in this manual 1 4 Nameplate Data The pump nameplate located on the drive adapter contains important information relative to the operation and servicing of the pump This information includes the direction of rotation arrow and the pump model and serial numbers The model and serial numbers must be used when ordering spare parts 1 5 Pump Rotation A rotation arrow on the nameplate indicates the direction of rotation Standard rotation of Moyno 2000 pumps is clockwise when viewed from the driven end of the pump 1 6 Model Number The pump model number is a series of numbers and letters which identifies the
