Continental Progressing Cavity Pumps

Continental, Progressing Cavity Pumps, Progressive Cavity PumpsContinental Progressing Cavity Pumps have time tested and proven unique characteristics that make them advantageous in performance over all other kinds of Pumps. They are built of various materials in many sizes with capacities from less than one gpm to over 500 gpm and pressures to 450 psi.

Positive Displacement

The turning ROTOR develops "positive pumping action" similar to a piston moving through a cylinder of infinite length. The pump pressure developed does not depend upon the speed of the rotating ROTOR. The capacity of the pump is approximately proportioned to speed. Slippage is relative to the viscosity, and pressure can be projected for particular operating conditions.

Uniform Discharge Flow

Fluids are uniformly discharged without pulsation in a constant steady flow. Displacement remains the same with each revolution of the ROTOR permitting accurate predictable metering relative to the fluid being pumped.

Internal Velocity Of Fluids

All Fluids are pumped with a minimum amount of turbulence, agitation, pulsation or separation disturbance.

Self Priming

Pumping action starts at the time the ROTOR is turned and it is capable of 28 feet of suction lift in an appropriate installation. The liquid being pumped acts as a lubricant between the ROTOR and STATOR and forms a continuous seal to project the pumping phenomena.

Solids In Suspension

Solid particles over a wide range of size and shape - as large as 1 1/8 inches in diameter, are pumped with no difficulty.


Pumps can be operated clockwise or counter clockwise with effective performance in most installations.


Pumps can be mounted Horizontally or Vertically and the Suction Port can be turned to any position for appropriated entry of the liquid.

...will handle any Liquid or Slurry that can be moved through pipe of the appropriate size.

Operation of the Continental Pump can be compared to that of a Screw Conveyor or Meat Grinder. As the ROTOR turns in the STATOR, the cavities between these components are filled with the liquid being handled and the liquid is progressively moved from the Suction Inlet to the Discharge Outlet of the Pump. The action continues as long as the ROTOR turns.

How This Unique Pump Works

Liquid enters the Suction Inlet under pressure or by gravity and as the ROTOR
1 turns within the flexible rubber STATOR
2 forming tightly sealed cavities
3 which moves the Liquid toward the Discharge Outlet.
Pumping action starts the instant the ROTOR turns. Liquid acts as the lubricant between the pumping elements.

ROTORS are made of Hardened Steel or Stainless Steel and are covered with a Chrome Plating to give resistance to corrosive and abrasive materials. Some liquids affect the Chrome Plating and in those applications a Non-Plated ROTOR should be used.

STATORS are metal tubes with internally molded cavities of Synthetic or Natural Rubber.
