4-20 mA or 0-10VDC signal input controls stroke frequency 10:1 Turn-Down Manual stroke length adjustment (0 to 100%) 10:1 Turn-Down. The VFD (Variable Frequency Drive), NEMA 4X, IP65 Enclosure is attached to motor mount frame.
General Description The BLACKLINE Series MD is a motor driven, spring return mechanical diaphragm metering pump for precise and accurate metering control. With many standard features, the Series MD includes oil lubricated ball bearings in a die-cast aluminum housing, long life reinforced PTFE diaphragm, micrometer style stroke length adjuster with a standard turndown ratio of 10:1 or up to 100:1 with the optional VFD Vector Drive. These reliable metering pumps are designed to perform in the widest range of chemical dosing applications.
Accuracy +/- 2% of maximum capacity
Temperatures to 40°C (104°F)
Rugged double-sided PTFE faced, long life diaphragm.
Oil lubricated ball bearings in die-cast aluminum housing.
Easy to Install, Rugged Construction Simple, intuitive design is easy to operate and maintain. Oil free, greased for life bearing with no more oil to buy or change. Compact and lightweight. Designed to withstand both indoor or outdoor rigors (when protected from precipitation and direct sunlight). Manual Stroke Adjustment Mechanism Manual micrometer style stroke adjustment; 10:1 turndown. Cartridge Check Valves Guided ball check system reduces back flow and enhances priming characteristics. Simple o-ring seals provide for reliable leak free performance and easy replacement. Materials of Construction See Specifications tab. BLACKLINE Metering Pump Possible Applications (with appropriate pump model and materials of construction.) Typical applications include: acids, caustics, polymers, bleaches, pH control, solvents, dyes/ink, catalyst, cleaning agents, and much more. When used in a system, the BLACKLINE Pump can be used in applications such as: Water Conditioning Service - Chlorination; Water Treatement Service - Odor Control; Wastewater Service - Polymer Injection; Process pH Treatment - Acids & Caustics; and Process Water - Corrosion Inhibitor.
WARNING: A pressure relief valve MUST be installed in the discharge line of all motor driven pump (order as a separate line item).
