Econ LD Series
Variable Speed Low Volume Peristaltic Pump - Econ LD Series From Stenner
The Econ LD, when precise low volume dosing, is a must.
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 incorporates the latest microprocessor technology with a simple potentiometer to control outputs with a 50:1 turndown. The outputs range from 0.04 to 8.1 ounces per hour, with pressures to 80 psi (1.3 to 240.0 ml/hr, pressures to 5.5 bar).
Ideal for pumping flocculants, coagulants, sanitizers, and a variety of solutions. Markets and applications include but are not limited to animal health for dip tank disinfection, flocculants for residential pools as a filter aid, analytical (specialty) for reagents, or industrial processing for additives.
