About the Merton Wheel Metering Pump Technical Manual and Instruction Manual
Merton Roll Metering Pumps Equipment Description and Use Features Performance Membrane Pump Heads Use the patented MARS Technology (Automatic Metering System) from the company, which combines the advantages of a variety of conventional pump heads. The high-performance diaphragm pump head eliminates the material-side disk diaphragm guard required for conventional hydraulic diaphragm heads, allowing the pump head to have both the "direct through" nature of the tubular diaphragm and the low NPSH (positive net suction pressure Head) requirements and other performance, but also effectively protect the diaphragm, to extend the life of the diaphragm, and to avoid the traditional metering pump head accuracy may change with the use of time weaknesses. Pump head material and diaphragm material ---- ensure that the metering pump can transport all kinds of chemical materials: on the Milton ROTOR metering pump technical manuals and instructions for use MiltonRoy metering pump can provide PP, PVC, PVDF, 361 stainless steel, Alloy 20 alloy, Kazakhstan 'S alloy and cast iron pump head and various materials such as Teflon / composite rubber, stainless steel and alloy materials to meet different process requirements. High-precision one-way check valve system ---- ensure constant high precision metering pump. Metering pump can deliver highly corrosive and harmful chemical medium of various concentration and temperature to pipeline or pressure vessel within specified time under normal or high pressure, such as nitric acid , Hydrochloric acid, sulfuric acid, caustic soda and so on Strong acid, strong alkali, weak acid, weak alkali or poisonous and corrosive mixed chemical liquid flow accuracy is very accurate, less than 0.5%, and according to production flow can be used in shutdown or boot Steplessly adjust the size of traffic. Conveying at a temperature of -30 to 450 degrees Celsius delivers a medium containing no solid particulates with a viscosity of 0.3 to 800 mm 2 per second (except for high viscosity pumps). 1. Plunger metering pump: Plunger in reciprocating linear motion, direct contact with the media transported in the import and export of one-way valve to complete suction and discharge liquid. For a variety of high pressure, low pressure, strong corrosive occasions. Accuracy of less than 0.5%. 2. Hydraulic Diaphragm Metering Pump: Reciprocating movement of the plunger in the cylinder, the pulsating force generated by the oil in the chamber to push the diaphragm back and forth, the purpose of suction and discharge liquid under the role of the inlet and outlet valves Because the diaphragm completely separates the plunger from the medium being conveyed, it prevents liquid from leaking outwards and its pressure can be used in the range of 0-35Mpa Hydraulic diaphragm metering pump Each configuration of three or two valve devices : Automatic oil filling valve, safety valve, exhaust valve. Accurate measurement, high pressure, corrosion resistance and no leakage is its significant advantage. 3. Mechanical driven diaphragm metering pump: hydraulic diaphragm with its difference is Slide bar and diaphragm directly connected to the work when the slide bar reciprocating push (pull) move the diaphragm back and forth, through the pump head opening and closing the role of one-way valve to complete suction purposes. It has a hydraulic diaphragm pump does not leak, resistance Outstanding advantages of strong corrosion, but also cheap In the occasion of low pressure and medium and small flow, the motor drives the worm and worm gear to make variable speed motion through the direct drive, and converts the rotational motion to reciprocating and linear motion under the action of the crank and connecting rod mechanism (this linear motion) The opening and closing of the inlet and outlet check valves creates a suction line for the purpose of delivering liquid.Miltonton metering pump is a reciprocating displacement pump used for precise metering and is used to deliver Liquid special volume pump, usually metering pump stability does not exceed 1% accuracy. In the installation should be noted that the outlet is higher than the import, to avoid siphon phenomenon, the supply voltage is stable and grounded, clean and spacious installation environment, good ventilation, pump head and injection valve required vertical installation, the attached tube can be tightened by hand, please Do not use tools; threads do not use raw material tape. For high pressure, low pressure, strong (weak) corrosive and high measurement accuracy of the occasion. Milton's metering pump is cast aluminum shell, high heat dissipation, the overall weight is light, suitable for all kinds of acid-base liquid, non-toxic and tasteless. The use of cam mechanism. Overall no leakage, can be placed in medicine troughs or pipes. Contact medium pump head is PVC, optional PTFE, and stainless steel. Cost-effective, generally applicable to the pressure less demanding water treatment industry. In the pump operation or stop when the flow can also be adjusted quantitative output. The diaphragm is made of multi-layer composite structure pressed, the first layer of ultra-tough Teflon acid-resistant film, the second layer of EPDM elastic rubber, the third layer thickness support core, the fourth layer reinforced nylon fiber reinforcement, the fifth EPDM elastic rubber Complete package of shoes, can effectively improve the diaphragm life.
