Exceeding Expectations

Neptune™ offers a wide range of pumping and metering solutions for chemicals used in all phases of the production, processing, refining, transmission and distribution of oil and gas products. Available in a wide variety of configurations, Neptune pumps ensure you'll find the proper solution for all norms and requirements of upstream, midstream and downstream applications.


Upstream applications are dominated by solar and pneumatic metering pumps, providing support to a variety of systems, such as methanol injections and corrosion inhibitors for wellheads, or paraffin blocking applications.


Midstream applications are a mix of all metering pump technologies including pneumatic, electric motor and solenoid actuated metering pumps. Typical applications include drag reducing agents to increase pipeline flow, corrosion inhibitor to prevent pipeline corrosion and freeze protection chemical.


Downstream metering pump applications are dominated by motor driven and solenoid actuated pumps. Some pneumatic pumps are utilized because of their high pressure capabilities and explosion proof characteristics as well as low cost. Applications include water treatment chemicals for boilers, cooling tower and waste water as well as process applications such as emulsifiers, demulsifiers, H2S Scavengers, filmers, neutralizers and antifoulants.

500 Series

Series 500 Hydraulic Metering Pumps are perfect for metering applications. Each pump features a variable Oil By-Pass™ stroke adjustment which will allow better valve performance than variable linkage designs.

600 Series

600 Series Hydraulic Metering Pumps are designed for high-volume, high-pressure applications and available in both simplex or duplex configurations. Utilizing similar design features as 500 Series pumps, the 600 Series can handle pressures up to 600 psi (41.4 bar) and offer capacity ranges from 126 gph (477 L/h) to 240 gph (908 L/h).
