What Neptune Chemical Pump Company does

Neptune Chemical Pump Company Inc. is a North American manufacturer and brand specializing in hydraulic and mechanical diaphragm metering pumps for precise chemical dosing in industrial applications. Its product portfolio spans more than a dozen pump series covering flow rates from 0.01 gph to 700 gph and pressures from 100 psi to 4000 psi, including the Series 500 and 600 dia-PUMP hydraulic diaphragm pumps, Series 8000 high-volume low-pressure units, low-volume 5003/5005 pumps, tubular diaphragm and V-Pumps for viscous fluids up to 20,000 cP, the Solar D solar-powered injection pump, MP7000/MP7100/7000Z mechanical diaphragm pumps, PZ-series solenoid metering pumps, and Abaque peristaltic hose pumps. Core proprietary technologies include Variable Oil By-pass stroke adjustment, EZE-CLEAN valve cartridges, hydraulically balanced Teflon diaphragms, the patented Polymaster Gatlin distribution head for polymer activation, and Solar D seal-less diaphragm technology developed jointly with Ferguson Beauregard (Dover Corporation). The company also markets Neptune Feed Systems (By-Pass Feeders, Bromine Feeders, Glycol Feeders), Neptune Systems (Polymaster blenders, Packaged Chemical Feed Systems), Neptune Accessories (Back Pressure Valves, Calibration Columns, Injection Quills, Pulsation Dampeners, Relief Valves, Sample Coolers, Electric Stroke Control), and Neptune Mixer Company industrial mixers.

The business operates as a brand under Metex Corporation Limited (Toronto, Canada), which serves as the exclusive Neptune pump representative for North America, handling all sales, technical support, and distribution via direct phone and email channels. Neptune's products serve four primary end markets: process industries (chemical metering in manufacturing), water and wastewater treatment (regeneration, pretreatment, waste treatment), oil and gas production (low-volume high-pressure chemical injection, including remote well applications), and agricultural industries (fertilizer injection and agricultural chemical metering). Revenue is generated exclusively through hardware sales of pumps, feed systems, mixers, and accessories on a quote-based model. Neptune has been serving North American customers for over 50 years through its product lines and over 25 years through the Metex representative relationship. Within the broader Dover Corporation pump ecosystem, Neptune is connected to PSG (which manufactures Abaque peristaltic pumps in Pennsylvania) and Ferguson Beauregard (co-developer of Solar D technology).
