Low Dose | Econ LD Series
The Econ LD is a low dose, compact, peristaltic pump for a variety of applications.
Flow Rate Outputs
0.04 to 50.7 oz/hr, pressures to 80 psi max.
1.3 to 1499.4 mL/hr, pressures to 5.5 bar max.
The Econ LD is for 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 incorporates the latest microprocessor technology with a simple 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).
Ideal for pumping flocculants, coagulants, sanitizers, and a variety of solutions. Markets and applications include but are not limited to injecting antiscalants for reverse osmosis systems, flocculants for pools as a filter aid, reagents for specialty applications or additives for industrial processing.
