Description
Industrial Applications for Metering Pumps
Nikkiso metering pumps can support controlled liquid dosing in industrial processes where accurate chemical delivery is required.
The correct pump configuration depends on the fluid, required dosing rate, operating pressure and process conditions.
Potential applications include:
- Water and wastewater treatment:
Chemical dosing, pH adjustment and water treatment processes.
- Fertiliser dosing:
Controlled delivery of compatible liquid fertilisers.
- Chemical processing:
Metered injection of compatible process chemicals.
- Corrosion control:
Dosing suitable corrosion-inhibiting chemicals.
- Food and pharmaceutical processing:
Applications requiring suitable materials and appropriate hygiene specifications.
- Oil, gas and petrochemical processes:
Chemical injection where the selected pump meets the required pressure, material and process standards.
What Information Is Needed for Pump Selection?
To help assess your application, prepare the following information:
- Required flow rate:
Normal and maximum dosing rates, including units.
- Installation details:
Site location, mounting arrangement and available power supply.
- Operating temperature:
Normal and maximum fluid temperatures.
- Wetted materials:
Preferred pump-head, diaphragm, valve and seal materials, if specified.
- Fluid or chemical:
Chemical name, concentration and relevant safety data.
- Control requirements:
Manual adjustment, variable-speed control, or a required external signal such as 4–20 mA, if applicable to the selected model.
- Discharge pressure:
Required operating pressure and any pressure variations.
- Existing pump details:
Manufacturer, series, model and nameplate photograph for replacement enquiries.
- Operating schedule:
Continuous or intermittent operation, including hours per day.
Chemical Compatibility and Material Selection
Chemical compatibility depends on the fluid, concentration and operating temperature. Pump head, diaphragm, valve and seal materials must be suitable for the specific application.
Provide your chemical details and operating conditions to help verify material suitability against the manufacturer’s specifications.
Frequently Asked Questions about Nikkiso Metering Pumps
How do I select a suitable Nikkiso metering pump?
Provide the fluid name and concentration, required flow rate, discharge pressure, operating temperature and control requirements. The existing pump model or nameplate is also useful for replacement enquiries.
Can a metering pump be controlled automatically?
Control options depend on the selected pump and its drive or controller. State the required control method or signal so the available configuration can be checked.
Does 2,160 mL/min apply to the entire Nikkiso metering pump range?
No range-wide claim should be made without verification. Flow capacity varies by pump series, model, operating frequency and discharge conditions. Check the current manufacturer’s specifications for the exact model.
What information is needed to replace an existing metering pump?
Provide the manufacturer, model number, nameplate photograph, required flow rate, discharge pressure, fluid details and installation requirements.
How do I check chemical compatibility?
Check the chemical name, concentration and operating temperature against the manufacturer’s guidance for the pump head, diaphragm, valves, seals and other wetted components.
Are spare parts available for Nikkiso metering pumps?
Availability depends on the model, component and current parts support. Provide the pump model and required part details for confirmation.
