PERISTALTIC METERING PUMPS SINCE 1957 |
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.

NOTICE: The information within this chart is solely intended for use as a guide. The output data is an approximation based on pumping water under a controlled testing environment. Many variables can affect the output of the pump. Stenner Pump Company recommends that all metering pumps undergo field calibration by means of analytical testing to confirm their outputs. |
