Precise Low Volume Injection
The Econ LD is a precise, compact, variable speed, peristaltic pump designed for reliably metering low volume amounts. The quiet, long lasting brushless motor, in a totally enclosed housing, offers premium quality at an economical price. The LD series is adjustable with a potentiometer to control outputs with a 50:1 turndown. The outputs range from 0.04 to 50.7 ounces per hour, with pressures to 80 psi (1.3 to 1499.4 ml/hr, pressures to 5.5 bar). The pump is also offered in 24VDC for installations where standard voltage is unavailable.
Ideal for pumping flocculants, coagulants, sanitizers, and a variety of solutions. Markets and applications include but are not limited to injecting anti-scalants for reverse osmosis systems, flocculants for pools as a filter aid, reagents for specialty applications or additives for industrial processing.
