Neptune Chemical Mechanical Metering Pumps

Neptune Hydraulic Diaphragm metering pumps are typically used for chemical metering in process and agricultural industries. Chemical metering pumps are available for high and low pressure applications with manual and electronic stroke control.

Neptune Series MP7000 Mechanically Actuated Diaphragm Metering Pump

  • The Series MP7000 Mechanically Actuated Diaphragm Metering Pump is the low-flow version of the MP7100 metering pump. The MP7000 incorporates the ruggedness of a hydraulic diaphragm metering pump, eliminates the need for intermediate fluid or hydraulic oil to actuate the diaphragm and eliminates the potential for gearbox oil to contaminate the process since it has an oil free gearbox design. The result is a pump design that provides reliable and accurate dosing.

Neptune 7000Z Series Mechanically Actuated Diaphragm Metering Pump

  • Neptune™ 7000Z pumps have been designed to handle a wide assortment of volatile chemicals and clear liquids at pressures up to 12 bar (174 psi).

Neptune Series MP7100 Mechanically Actuated Diaphragm Metering Pump

  • The Neptune Series MP7100 is a mechanically actuated diaphragm metering pump engineered from the ground up to be more robust and durable than similar mechanical diaphragm pump designs.
