Neptune™ Chemical Pump Co. Hydraulic and Mechanical Diaphragm Metering Pumps

Since 1961, Neptune™ Chemical Pump Co. has been a premier manufacturer of chemical metering pumps, chemical feed systems and chemical injection accessories for the mining and related industries.

Neptune’s hydraulic and mechanical diaphragm metering pumps are well-known for accurately and reliably injecting chemicals in many water-treatment applications, including those found in mining operations.

Other Neptune products include make-down systems that are used to prepare and activate liquid or dry polymer for injection into water and wastewater treatment processes, as well as a complete line of portable mixers.

Hydraulic diaphragm metering pumps

Neptune’s Series 500 and 600 metering pumps set the standard in innovative motor-driven design which delivers precision and long-term reliability. The EZE-CLEAN™ valve design features a double ball check design and can be removed without disturbing the piping.

The Series 500 and 600 pumps are the only hydraulic diaphragm metering pumps that feature a Variable Oil By-pass™ stroke adjustment, delivering better valve performance by allowing the valve checks to seat longer (even in heavy liquids often found in mining during the by-pass portion of the stroke).

Each pump’s flow rate can be controlled manually through the use of a micrometer dial, regardless of whether the pump is running or stopped. Stainless steel, PVC, Kynar® or C-20 liquid-end materials of construction and hydraulically balanced Teflon® diaphragms help make Series 500 and 600 pumps compatible with a wide range of fluids. Series 500 and 600 pump motors are explosion-proof for use in hazardous atmospheres.

Mechanically actuated diaphragm metering pumps

Neptune’s Series 7000 metering pumps have been designed for use in a number of process applications in the mining industry. The pump’s mechanical design eliminates the need for contour plates on the liquid side of the diaphragm, resulting in a simple, straight-through valve and head design that optimizes flow rates.

The pumps are self-priming and deliver superior performance when pumping chemicals that can off-gas, such as sodium hypochlorite. Series 7000 pumps have suction-lift capabilities that can exceed 20ft (6m) on water-like chemicals but are also versatile enough to handle fluids with viscosities in excess of 5,000 cPs. Pump flow rates are adjustable through use of a ten-turn micrometer dial and all moving parts can run submerged in oil. Liquid-end materials include stainless steel, PVC or Kynar® with Teflon® diaphragms.

Electronic stroke control for metering pumps

Flow rates of any Series 500 and 600 pump can be controlled automatically by a process instrument, or manually from a remote location, using the electric stroke control to change its stroke length. The electric stroke control is a one-piece, self-contained electric positioner, which is mounted directly on the pump. Perfect for hazardous mining conditions, the control is explosion-proof and features a manual override in the event of instrument signal or power loss.

Series 500 and 600 pumps can also incorporate a variable-speed drive that can be controlled automatically to change the pump’s stroke speed.

Neptune™ 500-D Series Hydraulic Diaphragm Metering Pumps Handle Challenging Mining Applications

Neptune™ Chemical Pump Co., a leading manufacturer of chemical metering pumps, designed its Neptune 500-D Series (Duplex) Diaphragm Metering Pumps for frother applications found in coal mine prep plants. In the preparation plant, the Neptune 500-D Series pumps diesel fuel from one pump head to coat the coal and feeds frother (alcohol) from the other pump head, which makes the coal float on top of the slurry so it can be extracted.
