What sophisticated metering pump selection?
When you select the metering pump, also we need to consider the required level of precision metering pumps, the greater the investment, the higher level of accuracy. Metering pumps are generally operating temperature -30 ~ 100 ℃, special metering pump operating temperature range is wider (such as high-temperature liquid metering pump with insulation jacket, the delivery temperature up to 500 ℃). For medium size, we require should be less than 0.1mm, for more than 0.1mm of media, we can be targeted to overcurrent pump structure be changed to meet the needs. For the viscosity of the medium, the general should be 0 ~ 1000mm / s, special metering pumps up to 6000 mm2 / s, the company has a high viscosity pump head. Mechanical diaphragm metering pump flow is the maximum flow rate under rated pressure calibration measured (at room temperature water transport), the flow rate if the pressure drops, the output will be higher than the calibration.
Determining the pressure: the selected metering pump rated pressure slightly higher than the actual maximum pressure required is generally higher than the 10 to 20%. Do not choose too high, the pressure is too high will waste energy, increase investment and operating costs of the equipment to determine the flow rate: the selected metering pump flow rate should be equal to or slightly greater than the desired process flow. Use of the flow metering pump manufacturer in metering pump 30 to 100% of the nominal flow range preferably, when the reproduction was repeated dosing accuracy. Taking into account the economic and practical, the proposed metering pump flow actual need to select 70 to 90% of the metering pump rated flow. Determine the pump head (liquid end)
Material: The metering pump to determine the specific model specifications, according to the property stream media over the choice of the material flow part, this step is very important, if you choose inappropriate dosing device manufacturers will result in corrosion damage to the media or media flow components leak contaminated systems. Serious cases may cause a serious accident if you are not sure, please consult our company.
