Neptune Metering Pumps

Neptune Metering Pump

• What is a chemical metering pump and how does it work?

  A metering pump is a specialized type of positive displacement pump designed to deliver precise, small amounts of liquid with controlled flow rates.

• What are the different types of metering pumps?

  Neptune offers mechanical, hydraulic and electronic metering pumps. Each can provide a high level of accuracy and repeatability over a wide range of flow rates, pressures and chemical makeup.

• What are common applications for metering pumps?

  Neptune metering pumps can be used in a wide variety of applications, including water treatment, food and beverage, agriculture, boiler treatment, and energy and power generation. Any time fluid needs to be dosed in an accurate and repeatable amount, a metering pump would be the best option.

• What are the benefits of using a chemical metering pump for dosing applications?

  Neptune hydraulically actuated chemical metering pumps are ideal for accurate dosing applications where precision and repeatability are required. These pumps offer a simple design that is easy to disassemble, assemble and troubleshoot, with a flow precision and accuracy of 1–2% as well as easy-to-clean valves that allow for maximum ease of maintenance. The diaphragm in a Neptune pump is also hydraulically balanced to reduce the frequency of maintenance.

• How do I troubleshoot a chemical metering pump that stopped working?

  Many issues with chemical metering pumps stem from valve blockages or diaphragm wear, especially in corrosive dosing applications. The first thing you should check on your metering pump when it stops working is the oil. If the oil is old, replace it with new oil and consider replacing it more frequently. Then you should check the suction and discharge valves. These valves should be able to move freely and allow fluid to pass through the pump. If these valves do not move freely, clean or replace them. Finally, check the diaphragms on the pump. If there are any cracks, dimples or tears in the diaphragm, the pump could fail to operate and would need replacement.

• What should I consider when choosing a chemical metering pump for dosing applications?

  When selecting a chemical metering pump for dosing applications, key factors include fluid compatibility, materials of construction, flow rate, discharge pressure, environment for the pump and method of control.

• Can Neptune chemical metering pumps handle viscous or corrosive fluids?

  Neptune pumps can handle both. Neptune metering pumps come in a wide range of materials of construction, including stainless steel, PVC, C-20 and PVDF, making them suitable for use with corrosive fluids. Neptune metering pumps can also handle viscosities up to 5,000 cps.
