Overview
The BLACKLINE Series MD is a motor-driven, spring-return mechanical diaphragm metering pump with precise and accurate metering control. The Series MD has several basic features, including oil-lubricated ball bearings in a die-cast aluminum body, a long-life reinforced PTFE diaphragm, and a 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 dependable metering pumps are intended to function in a wide 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.

Mechanism for manually adjusting strokes
Stroke adjustment is done manually using a micrometer, with a turndown of 10:1.

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).

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.
