Continental Progressing Cavity UltraPump Specifications

Cataloged Specifications

Continental progressing cavity pumps as cataloged in the 2021 Product Catalog and the CK 2000 Series catalog: rigid stator CL, CM, and CG families, the CK 2000 Series, and the CP/CPM/CPML wobble stator line. The CJ hopper family is cataloged dimensionally only, so it carries an envelope but no model rows. Covers water-service flow and pressure envelopes only. Chemical compatibility is never resolved here; fluid details go to the RFQ handoff.

Continental Product Catalog, published 2021CPCP Catalog 2021 RVSDMirrored copy: Continental-Product-Catalog.pdf

2021 factory catalog (footer CPCP Catalog 2021 RVSD, printed 4/5/21). Printed page numbers match PDF pages. Performance data is stated for water at 70 F; viscosity, particle size, and abrasive deratings are printed as separate guides on pages 40-41. Current factory literature may supersede these figures. Verify against the factory before quoting.

Continental CK Series 2000 Catalog, published Not statedNo document code printedMirrored copy: Continental-CK-Series-2000-Catalog.pdf

Undated factory catalog for the CK 2000 Series. Printed page numbers match PDF pages. Its pump table (page 21) is stated for water at 68 F with 70 durometer stators and overlaps the Product Catalog page 37 table without matching it model for model; the differences are flagged in the CK family reviewNotes. Performance curves on pages 49-60 were not extracted to rows.

CK 2000 Series

Industrial design for the heavier applications of sewage, industrial waste, polluted liquids, and slurries. Positive displacement, non-pulsating flow; handles heavy radial thrust loads. Rows merge the Product Catalog page 37 table (water at 70 F) and the CK catalog page 21 table (water at 68 F, 70 durometer stators); each row records capacity at its maximum rated pressure at the printed maximum RPM.

ActuationRigid stator progressing cavity, heavy duty crown gear joint drive connections

Flow envelope5 to 2400 US gpm

Max pressure780 psi

Wetted head materials: Cast iron (code C), 316 stainless steel (code S). Body materials per the CK selection guide; internals and rotor in alloy steel (code D) or 316 stainless (code S). The Product Catalog page 4 states the same castings line-wide.

Capable of pumping foreign materials with particle sizes up to 2 in. in diameter. (p. 36)
Self-priming with suction lift up to 28 ft, based on water. (p. 36)
Performs with equal efficiency in either direction. (p. 36)
The CK selection guide derates speed and capacity by element size for viscosity: the 008 elements fall from 750 RPM and 54 gpm in the lowest viscosity band to 70 RPM and 3 gpm at 100,000 cps. (p. 23)
Abrasive service derates speed and capacity: the 008 elements fall from 750 RPM and 62 gpm with no abrasives to 300 RPM and 25 gpm in heavy abrasive service. (p. 24)
