Pulse Metering Pump

The new series PZ pulse metering pump is well suited for accurate, reliable injection of a wide range of liquid materials, including chemicals, nutrients and disinfectants. An economical alternative to Neptune's series PX, the PZ pump features the same design, which eliminates the need to change pump models to match the available voltage. The pump operates on any single-phase voltage from 94 VAC to 264 VAC.

Chemical delivery with the series is constant and stable through voltage fluctuations. The pump is designed to be accurate at all dial settings, even at low feed rates. The number of pulses per minute can be manually adjusted from 15 to 300 pulses with an easy-to-use, calibrated dial. Accurate chemical injection throughout its range of operation is ensured by the unit's high stroking speed and volumetric efficiency.

Accessories included with each pump include a foot valve strainer, a back pressure/check valve injector with quill, and suction, discharge and air release tubing. The unit is suitable for outdoor service with its dust-proof, UV and water-resistant enclosure.
