Encore 700

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.

The UGSI Encore 700 is the new and improved Wallace and Tiernan Series 44
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.
