Metering pump selection as follows: First, determine the pressure: the selected metering pump rated pressure slightly higher than the actual maximum pressure desired, generally 10 to 20% higher. Do not choose too high, the pressure is too high will waste energy, increase investment and operating costs of the equipment. Second, determine the flow: the selected metering pump flow rate should be equal to or slightly greater than the required flow processes. Metering pump flow rate range of 30 to 100% of rated flow range metering pump preferably, this time metering pump repeat reproduction with high precision. Taking into account the economic and practical, the recommendations of the actual needs of the flow metering pump to select 70 to 90% of the metering pump rated flow. In determining the head (hydraulic end) Material: specific models metering pump size is determined, then according to the choice of the media over the property stream flow part of the material, this step is very important, if you choose properly, will cause corrosion damage to the media or media flow components from leaking systems. Serious cases may cause a major accident, if you are not sure energy saving metering pump, please consult our company. Changzhou City, Xiao source Machinery Co., metering pumps type: plunger type 1, the price is low 2, flow rates up to 76 m 3 / h, the flow in the range of 10 to 100 percent, measurement accuracy of ± one hundred One minute, pressure up to 350 MPa. When the outlet pressure changes, the flow rate is almost constant. 3, capable of delivering high-viscosity media, suitable for conveying corrosive slurry and hazardous chemicals. 4, seal in packing phosphate dosing pump, there is a leak, the need to periodically adjust the packing. Packing and plunger wear dosing pump sets, the need for packing rings for pressure washing and emissions. 5, no safety relief devices. Mechanical diaphragm 1, lower prices. 2, no dynamic seals, no leaks. 3, capable of delivering high-viscosity media, abrasive slurries and hazardous chemicals. 4, the diaphragm subjected to high stress, lower diaphragm life. 5, the outlet pressure of 2 MPa or less, suitable for a small range of flow; measurement accuracy of ± five percent, when the pressure from the smallest to the largest, the flow changes up to ten percent. 6, no safety relief devices. Hydraulic diaphragm 1, no dynamic seal, no leakage, safety relief devices and simple maintenance. 2, the pressure up to 35 MPa; 10︰1 flow in the range, measurement accuracy of ± one percent; pressure increased by 6.9 MPa and flow decreased five percent to ten percent. 3, higher prices. 4, suitable for medium viscosity media.
