New Products & Processes The PDM-1 is very unique from other equipment claiming to offer the same results. The dictionary defines a screw conveyor as a device for moving loose materials, consisting of a shaft with a broad, helically wound blade rotating in a tube or trough. While other equipment manufacturers try to mix the materials with a screw conveyor, we use ours to move and meter loose material from the hopper up to our elevated mixing chamber. The PDM-1 has a special mixer chamber that does all the work to continuously mix the materials. It can mix concrete consistently from a pre-moistened condition to a full wet-mix design. Once the machine is properly set up, there are no adjustments to make for day-to-day use. Features: • One-person operation. • 12 V on/off operation and can be connected to other equipment to operate simultaneously. • Can be operated by remote. • Both wet- and dry-mix operation. • One switch for total on/off operation. • Designed for easy assembly and disassembly. • Can be moved by forklift at mixer end. • No wasted material and very minimal dust. • Digital flow meter to measure water. • Revolution counter to meter volume. • Volume controls to meter speed of conveyor and mixer. • Precise needle valves to meter water to mixer tub. • Manual overrides in case of emergency. • Forward and reverse functions for easy cleanup. • Epoxy paint. • Lower auger liner AR 450 and mixer tub AR 400. • Auger screw uses AR 400 material with hard surface of the leading edge. • Mixer paddles use AR 400 material with hard surface. • Can use wide-throat bulk bags or small bags with a bag breaker. • Weatherproof NEMA 4 control panel ULC and UL certified. • High-capacity oil to water oil coolers. • Hour meter/tachometer. • Emergency stop button and safety cover switches. The PDM-1 pre-dampener/mixer uses a dual hydraulic system with variable adjustable flow controls. Powered by either an electric- or diesel-powered motor, the simple design makes them easy to operate, troubleshoot, and service. A variety of slump output ranges for dry or wet mix makes the PDM-1 a top performer for any application. Contact Canusa Equipment at (604) 526-5151 or visit www. canusaequipment.com. Schwing Adds Tier IV Engine | SP 500 Stationary Pump Schwing is now providing their popular SP 500 stationary concrete pump with a Tier IV-compliant Caterpillar diesel engine. This is a response to government-mandated reductions in harmful exhaust gases from diesel-powered equipment. The California Air Resource Board (CARB) requires Tier IV compliance for stationary pumps used on public and private projects. Other parts of the country are also requiring Tier IV compliance depending on the locale and project. The CAT® C3.4B diesel is rated at 74.5 hp while providing durability and fuel efficiency. Customers will enjoy unprecedented global parts, service, and repair options through the CAT® dealer network. The SP 500 is a versatile machine with up to 45 yd3/h (34 m3/h) output and 1100 psi (8 MPa) maximum pressure on the material. The machine excels pumping grout, shotcrete, or concrete. The twin-cylinder, all-hydraulic pump handles up to 1.5 in. (38 mm) aggregate with its 6 in. (152 mm) diameter pumping cylinders operating through a 39 in. (1000 mm) stroke. Sequencing the concrete to the pumping cylinders is the rock valve that enjoys proven reliability on Schwing’s largest concrete pumps. Besides pumping harsh mixtures, the rock valve cleans up faster, using less water for high utilization on multiple projects in a day. Dual-shifting cylinders provide positive valve actuation for smooth discharge. The open loop hydraulic system combines with the CAT engine to provide all-day economy from the 20 gal. (76 L) fuel tank. Schwing SP models can be provided as skid-, truck-, or trailer-mounted units. A convenient control panel on the side of the machine includes switches for on/off, forward/reverse, and hopper agitator. Electric power is also available. A cable remote is standard with optional radio remote control. For more information on the Tier IV compliant SP 500 and the entire line of Schwing stationary pumps, visit www. schwing.com.
