Techcon TS7000 Feed Screw, 8-Pitch High Output, 440C Stainless

Description

The Techcon TS7000 feed screw is machined from 440C stainless steel and sized for the 8-pitch high output rotary auger valve. As one of the core dispensing valve parts in the TS7000 system, it drives fluid through the valve chamber with a precision helical thread that meters flow far more consistently than a pneumatic piston valve.

Where Dispensing Valve Parts Like This Fit

The TS7000 platform uses a divorced cartridge design. The feed screw and chamber sit in a replaceable cartridge separate from the drive motor, so a worn screw can be swapped without disturbing the motor or recalibrating the whole valve. Shops running high-volume dot and bead work on adhesives, greases, and epoxies use the 8-pitch high output screw when they need faster fill rates than the standard 8-pitch screw without moving to a 32-pitch, low-flow setup. It installs into the same cartridge housing used across the TS7000-DCX-8 and TS7000-DCX-8HO valve lines.

How These Dispensing Valve Parts Hold Up

440C stainless resists the abrasive wear that ages ordinary steel screws faster in filled or particulate-heavy fluids, including metal-filled epoxies, silver conductive adhesives, and abrasive-loaded sealants. The hardened thread profile keeps its pitch accuracy over repeated duty cycles, which matters because a worn thread shows up immediately as inconsistent dot size or bead width on the line.

Techcon machines the thread lead on this screw to tight tolerance so output per motor rotation stays predictable across a production shift, which is the main reason shops standardize on OEM feed screws instead of running a worn one past its service life. A screw that has lost thread definition still turns and still feeds fluid, but the volume per revolution drifts, and that drift shows up as parts that pass a spot check early in a run and fail a check two hours later. Order the matching cartridge housing separately if the chamber bore is also worn. Replacing the screw and chamber together as a set restores dispensing accuracy faster than replacing the screw alone on a valve that has seen heavy duty cycles.
