Application The Twistork Helix Mixer is intended to mix and maintain paints and similar fluids in closed-head, 55-gallon (200-liter) drums with 2-in. npt bung connections. The Twistork Helix Mixer provides suction porting through its siphon tube, which allows you to siphon fluid to a pump while mixing it.

Installation WARNING FIRE AND EXPLOSION HAZARD Always maintain a minimum of 1 in. clearance between rotating agitator parts and container to prevent sparks from contact. J H Typical Installation air line lubricator agitator motor 03024 Fig. 3 CAUTION air line filter mix tank air regulator (reference only) and gauge The bearing nut (8) is made of acetal, which is not compatible with some of the solvents used in paints or coatings and is not compatible with acidic fluids.

Installation Air Line Accessories The following air line accessories help to increase motor life and ease of operation. Air Line Filter Air line filters remove harmful dirt and moisture from the air supply. Order one of the following: Part No. 106148: 3/8 npt(f) air line filter Part No. 106149: 1/2 npt(f) air line filter Air Line Lubricator (for Model 236629 only) CAUTION Not lubricating the air motor will cause air motor failure.

Installation Installing the Mixer The mixer weighs 24 lb (11 kg). To manually lift it in and out of the drum, grasp the housing (3), and guide the helix tube (7) through the drum bung. See Fig. 5. Accessory handle Part No. 189658 is available so you can connect a lift hook to raise and lower the mixer or hang the mixer to store it. CAUTION To avoid damaging the siphon tube, lower the mixer to the drum bottom; do not drop it. 5.

Operation WARNING MOVING PARTS HAZARD To reduce the risk of serious injury, including cuts, amputation of fingers, and splashing in the eyes or on the skin: Always shut off the mixer and disconnect the air line before you check or repair the mixer. Maximum Siphon Flow Rate The volume of fluid that can be siphoned through the mixer inlet is determined by the viscosity of the fluid. The maximum flow rate is approximately 12 gpm (45 lpm) with 100-centipoise fluid. The maximum flow rate is approximately 1.

Operation 1. Turn on the air supply to start the mixer. Regulate the helix speed with the needle valve (18). Shutting Down 2. Operate the mixer continuously when supplying paints or other fluids to the system. 1. To stop the mixer, close the needle valve (18), or disconnect the quick-disconnect (F), or close the air valve in the air supply line. Model 236629 shown Â 18 F 2.

Maintenance Prolonging the Life of the Bearing Nut CAUTION Use a compatible solvent to clean parts. The bearing nut (8) is made of acetal, which is not compatible with acidic fluids. Check your material data sheet and/or supplier for compatibility. Avoid getting any solvent on the air motor belt. 5. Apply PTFE spray lubricant to the siphon tube (4) inlet end only. Install the siphon tube through the top of the mixer housing (3). 6.

Maintenance Lubricating the Air Motor (Model 236629 Only) CAUTION Not lubricating the air motor will cause air motor failure. If an air line lubricator is not installed, the air motor must be manually lubricated every 8 hours. Lubricate the agitator air motor by placing 10–20 drops of SAE #10 light oil in the motor’s air inlet. Run the agitator for about 30 seconds. Correcting a Bad Suction Line Seal Air getting pulled into the suction line makes the pump inefficient.
