Product Spotlight: Metering Pumps

Sept. 11, 2008
The Tacmina PZ Series electronic metering pumps accurately and reliably inject liquids, including chemicals, nutrients, and disinfectants.

The pump’s flow rate and accuracy aren’t affected by voltage fluctuations; the unit operates at any single-phase voltage from 94 to 264 Vac.

The PZ pumps come in manual control, external input, and programmable models, in a wide range of sizes and pressures (from 1 to 1,300 ml/min at pressures up to 220 psi). Models PZD-32/52 and all PZiG Models have built-in calibration and allow accurate direct entry of feed rate in ml/min. All models have onboard control features, including pH and residual chlorine control – without requiring a separate PID controller. An available flow checker measures flow on the smaller models.
