Continental Progressing Cavity Pumps Model CP- Brochure

Application, Installation and Operation Instructions for Dis-Assembly and Assembly of Model CP Continental Progressing Cavity Pumps Speed, temperature, viscosity, suction lift, discharge pressure, abrasive content and corrosive action of the liquid to be handled should all be considered in applying these pumps. Pump should always be filled with the liquid to be handled before running. The liquid serves as a lubricant and is easily poured into the pump through the discharge port before final assembly of the piping or hose connections. A filling tee with a plug or valve can be installed above the discharge port for ease in filling. Liquid to be pumped should never exceed 190° F temperature. Maximum speed that any of these pumps should be run is 2,800 rpm and then only in handling thin, abrasive-free liquids. Preferably the speed should be 1,750 rpm for longest life. When liquid contains abrasive materials or is viscous, the speed should be reduced. For various viscosities of abrasive-free liquids, the maximum operating speed of the pump is set forth below: Capacity and life of these pumps will depend upon the liquid being handled. Piping to pump should be properly selected and should not be smaller in size than the suction and discharge ports of the pump. All pipe and hose fitting joints should be tight. Discharge lines should be open or if pump is operated in an enclosed system, provision should be made for pressure relief when the pump pressure exceeds the limits as set forth for each model pump. Pump bearings do not require lubrication as they are pre-lubricated. We recommend that the pump be flushed after its use. PUMP SHOULD NOT BE RUN DRY. We will be glad to collaborate on any proposed applications. Fill out the CONTINENTAL PUMP APPLICATION DATA sheet and return it for a prompt recommendation. Please request copies if not with this Bulletin. When necessary to dismantle pump, disconnect pipe or hose at suction and discharge ports. Remove bolts which connect Suction Housing to Discharge Housing. Rotor can be removed by turning it in opposite direction to pump rotation. Grip Rotor with wrench, whose teeth have been protected, and hold Shaft externally- hold Motor Shaft with Screwdriver on CPM Models. To replace Rotary Seal, unscrew Flexible Joint with 3/16” hexagonal wrench. Rotary Seals can be easily removed from shaft. To replace Pump Bearings remove Retaining Ring and then tap shaft at threaded end. Protect threaded end with wood or rubber block. If any parts of the Rotary Seal are worn or broken, replace complete Rotary Seal. The parts of each Rotary Seal are precision matched and are not interchangeable. Illustration below shows how Rotary Seal is installed by parts and how it looks after it is complete. Part A is pressed into the Discharge Housing. Care should be taken to assure that rubbing surfaces of Part A and B are not scratched. Moisten rubber sleeve of Part B with water to permit easy fitting over Shaft. Part B is then slipped down Shaft until face fits firmly against face of Part A. Part C is placed against Part B. Flexible Joint should then be screwed into Shaft against Part C. Use hexagonal wrench to tighten Flexible Joint, and then screw Rotor onto Flexible Joint. It is not necessary to tighten Rotor with a wrench as it is self-tightening when the pump starts. Moisten inside of Stator with water and slip it over Rotor. Mount Suction Housing to Discharge Housing and fasten with body screws. Refill pump with liquid to be handled, connect pipe or hose to suction and discharge ports and pump is ready to run.

A complete book of instructions is furnished with each Gasoline Engine Model and should be thoroughly read and followed. After gasoline engine is made ready by filling with engine oil in crank case and gasoline in tank, fill Discharge Housing of the pump with the liquid to be handled. Complete suction and discharge port connections of pump and start engine with rope provided. We recommend that the pump be drained and flushed after each use.
