The Encore 700 (Formally the Wallace and Tiernan Series 44) is a rugged, heavy-duty mechanical diaphragm metering pump available with six diaphragm sizes and double simplex capability to handle capacities up to 660 gallons per hour and backpressure to 175 psi.
- Non-Loss motion stroke adjusts mechanism for reliability and longevity.
- Available in either a direct drive configuration or a pulley coupled arrangement for additional 4:1 turndown on stroke frequency.
- Manual control or control via an automatic stroke length positioner or variable speed drive or both.
- Optional diaphragm leak detector.
UGSI Has Taken the Superior Wallace and Tiernan Series 44 and IMPROVED IT with a More Rugged Drive Mechanism and A Composite Diaphragm for Longer Life and Easy Serviceability.
- Short suction and discharge ports minimize friction losses and cavitation, improving hydraulic characteristics.
- The composite diaphragm is manufactured to stringent specifications to ensure long life. The design incorporates PTFE facing, for the highest degree of chemical resistance.
- This double diaphragm isolating design eliminates the risk of cross-contaminating gearbox lubricant and process fluid.
- The proven design includes wide flow paths and four-point guides to control ball rise and assure proper seating. The valve housing is compression-sealed to the pump head and pipe connectors by O-rings and is easily removed for the service or replacement without disturbing the external piping.
- Available with standard induction, variable speed, or inverter duty motors for wider operating ranges and automatic process control.
- This proven (Wallace and Tiernan 44 Series design) provides robust mechanical assembly features and liberal use of heavy-duty parts.
- An optional diaphragm leak detection system senses the early stages of diaphragm failure.
- Obtain precise and highly repeatable feed rate settings with a 10-turn, micrometer-type stroke length adjuster. A percent scale and vernier indicate stroke length in 0.25% increments.
- Proven, reliable drive and control mechanism with precision liquid end design offer superior metering and process control performance.
Dry Chemical Feed Equipment & Control
UGSI Chemical Feed Series 32-050 and 32-055 Volumetric Screw Feeders are designed to feed a wide range of water and wastewater treatment chemicals as well as industrial process chemicals and dry materials. Utilizing 4 different feed screw sizes, capacities from 0.03 to 50 cubic feet are available. The continuous operating range is 20:1, extendable to 60:1 by belt position on a stepped pulley.
Series 32-050 Feeder – This economical feeder features a constant speed feed screw that is controlled by a manually-set percent timer. The feeder cycles on and off over a 1-minute feed cycle depending on the timer setting.
Series 32-055 Feeder – This highly adaptable feeder features a variable speed feed screw with 3 different control arrangements: Manual control via a feeder mounted potentiometer; Start-stop control from a remote interlock; mA control from a flow signal or remote plant control.
