Chemical Pumps


Neptune, part of PSG, a Dover company and a worldwide leader in specialty pumps, is pleased to announce the availability of its new NSP Series Solenoid Metering Pumps and NXP Series Stepper Motor-Driven Metering Pumps for chemical applications that require reliable and accurate dosing.


Featuring a durable, low-maintenance solenoid drive equipped with double-ball valves, the NSP Series from Neptune ensures consistent and precise dosing of a variety of chemicals, including acids, alkalis, coagulants and flocculants. The compact design and easy-to-use control of the NSP Series provide more efficient operation and shorter setup times for the operator. The small footprint allows it to easily integrate into dosing systems with limited space. The NSP Series is available in manually, analog, and pulse-controlled models.


Thanks to its compact design and intelligent-drive concept, the Neptune NXP Series combines the advantages of a solenoid-driven pump with the precision of a motor-driven pump. This makes it an ideal solution to safely feed chemicals in highly accurate, reproducible applications. The NXP Series is fully adjustable to produce a constant supply stream during low-pulsation dosing, and the stepper motor with its wear-free tooth belt dive ensures a homogeneous and gentle dosing process. Available in six sizes, the NXP Series is plug-and-play and includes a universal power supply unit.
