Ritter ZWM 11-D Helical Static Mixer, B-Style Connection

Description

The Ritter ZWM 11-D is a compact helical static mixer built for two-component cartridge systems that need a short, low-volume mix path. Eleven helical elements fold the resin and hardener streams together before the material reaches the outlet, so the ratio stays even from the first bead to the last drop in the cartridge, with no manual stirring and no separate mixing cup to clean out between shots.

Where This Static Mixer Fits

This mixer suits B-style cartridge guns running small two-part adhesives, sealants, and potting systems where cartridge volume is modest and a longer nozzle would waste material on every shot. Shops running touch-up repairs, small assembly bonds, prototype builds, or lab-scale dispensing get full-length mixing without stepping up to a bigger cartridge or a longer, higher-waste nozzle. The B-style connection locks onto compatible cartridge outlets for a quick, secure fit during nozzle changes, and the short 88 mm body keeps the working end of the gun close to the work surface for tight spaces and detail work. Swapping a spent mixer for a fresh one takes seconds, so a single cartridge gun stays in service through a full shift of intermittent small bonds.

How This Static Mixer Performs Under Load

Eleven mixing elements packed into an 88 mm body are enough to fully blend low to medium viscosity two-part systems at the mix ratios common to B-style cartridges. The 6.5 mm outlet keeps bead placement controlled for narrow bond lines, small fillets, and precision dispensing where a wide bead is not the goal. Ritter molds the mixer body to hold its shape under cartridge gun pressure, so the helical elements keep their spacing through the full length of the cartridge instead of collapsing or channeling partway through the shot, which is what causes streaky, unmixed material at the tip on cheaper mixers. Consistent element spacing also means less scrap from partially cured or off-ratio material toward the bottom of the cartridge.

Ritter ZWM 11-D Specifications

Chemical Concepts stocks the ZWM 11-D for same-day shipment alongside the rest of the Ritter B-style mixer lineup, so a shop can standardize on one cartridge gun platform and swap mixer lengths by job without changing suppliers. Browse the dispensers, mixers, and nozzles category for compatible cartridge guns, tips, and other Ritter mixer lengths carried in the same connection style. Ritter GmbH, part of Avantor, manufactures the full B-style and bayonet mixer range this product belongs to. See the Ritter GmbH site for the broader cartridge and mixer catalog.
