How to Size and Select Your Metering Pump



 

Hydraulic Metering Pumps

Series 500 "dia-Pump"

neptune-500series bkgdCheck out our most popular and versatile Neptune pump, the 500 Series Neptune Hydraulically Actuated "dia-pump."  Variable Oil By-pass™ stroke adjustment allows better valve performance than variable linkage designs. The valve checks have extra time to seat even in heavy liquids since they are idle during the by-pass portion of the suction and discharge strokes.

The 500A Series is the Standard "dia-Pump" Simplex Only.

Metering Pumps--Neptune Low Volume Pumps

Special Application Pump

Neptune5003LVTNeptune Model 5003/5005 hydraulic diaphragm metering pumps are built to deliver very low flows, repeatable and accurate ranging down to quarts per day. Discharge pressures are higher than are possible with mechanical diaphragm pumps. Explosion-proof models are available for use in hazardous atmospheres.

These pumps are especially popular in oil/gas production, oil recovery and refineries. Typical applications include the injection of antifoam agents, corrosion inhibitors and other additives injected at very low volumes but high pressures. These pumps are also used for neat feeding of boiler chemicals.

  • Design Features/Benefits
  • High discharge pressures, to 3000 psi (210 kg/cm2) Exceeds limits of most small pumps, ideal for high pressure systems
  • EZE-CLEAN™ valves -- Cartridges can be removed for cleaning without disturbing piping
  • Electric stroke-length control available -- automatic capacity control in response to standard 4-20 mA process signal (variable speed drives may not be used with Models 5003/5005 due to low stroking speed)
  • Explosion-proof motors available -- suitable for use in hazardous atmospheres
  • Low flow-rates–quarts/day -- accurate, reliable chemical feed

Neptune High Viscosity Metering Pumps

Purpose

Neptune500VSseriesNeptune high viscosity, flat diaphragm "V-Pumps" are designed to accurately meter viscous fluids up to 5000 cP such as polymers and other thick liquids.

Features/Benefits

  • Handles moderate viscosity fluids.
  • Standard flat diaphragm.
  • Large internal porting with a large, single ball, suction check valve.
  • Capacities to 29 gph (109 lph) at 100 psi (8 kg/cm2).
  • Available in all 316SS with SS trim.
  • Electric stroke control options and variable speed drives.
  • Variable Oil By-pass™ stroke adjustment mechanism provides better valve performance than variable linkage designs.
  • Teflon® diaphragm withstands most chemicals.

Variable Oil By-pass™ stroke adjustment allows an adjustable time delay between the end of the suction stroke and the beginning of the discharge stroke. This delay permits the ball to seat fully before pumping resumes, even in the heaviest liquids, so that pumping accuracy remains high.

Neptune Mechanical "dia-Pumps"

Series MP7100 Mechanical "dia-Pumps"

PurposeNeptune 7000 Series Pump

The Neptune Series MP7100 "dia-PUMP" is a mechanically actuated diaphragm metering pump designed for water, wastewater and process applications.

Features

The mechanical design eliminates the use of contour plates on the liquid side of the diaphragm. The simple, straight through valve and head design allows improved flow characteristics.

  • Self-priming
  • Superior performance when pumping chemicals such as sodium hypochlorite, which can off-gas
  • Suction lift exceeding 20 ft. on water-like chemicals
  • Easily handles viscosities in excess of 5000 cps
  • Maximum capacities range from 12 gph to 300 gph at 150 psi, depending on model
  • PVC, Kynar, and 316SS liquid ends available
