CIRCOR Announces Zenith Series PEP-II Precision Gear Pumps Ideal for Lithium Battery Blown Film Polymer Extrusion Applications
Offers precise, pulseless, repeatable metering of polymers
CIRCOR International, Inc., a leading manufacturer and marketer of differentiated technology products and sub-systems, announces its Zenith PEP-II Series precision gear pump, ideal for blown film extrusion processes used to manufacture lithium battery separators, as well as other pump models for lithium battery additive, coating, sealant, and adhesives applications.
Featuring low pulse polymer metering and dosing, Zenith PEP-II pumps offer extremely precise repeatable metering, as well as near-constant flow without the need for expensive flow meters and control systems. When used as a high-pressure extruder pump, Zenith reduces extruder pulse at the die.
Zenith PEP-II Series pumps are manufactured in Monroe, NC, and are highly accurate, significantly reducing downtime. Their low pulsation and accurate flow enhance product quality. Featuring hardened tool steel, they offer long life and robust construction.
Zenith Pumps provides typical drive and control packages, as well as custom systems designed to meet customer specifications for precision extrusion applications. The standard extrusion control package consists of a motor and reducer mounted on a common base plate, with speed controlled by a Zenith ZVD digital speed controller.

T.J. Davies' Retention Knobs
Our retention knobs are manufactured above international standards or to machine builder specifications. Retention knobs are manufactured utilizing AMS-6274/AISI-8620 alloy steel drawn in the United States. Threads are single-pointed on our lathes while manufacturing all other retention knob features to ensure high concentricity. Our process ensures that our threads are balanced (lead in/lead out at 180 degrees.) Each retention knob is carburized (hardened) to 58-62HRC, and case depth is .020-.030. Core hardness 40HRC. Each retention knob is coated utilizing a hot black oxide coating to military specifications. Our retention knobs are 100% covered in black oxide to prevent rust. All retention knob surfaces (not just mating surfaces) have a precision finish of 32 RMA micro or better: ISO grade 6N. Each retention knob is magnetic particle tested and tested at 2.5 times the pulling force of the drawbar. Certifications are maintained for each step in the manufacturing process for traceability.
