Milton Roy Metering Pump Technology B210
24Pages

he metering pump is a positive displacement chemical dosing device with the ability to vary capacity manually or automatically as process conditions require. It features a high level of repetitive accuracy and is capable of pump- ing a wide range of chemicals including acids, bases, corrosives or viscous liquids and slurries.The pumping action is developed by a reciprocating piston which is either in direct contact with the process fluid, or is shielded from the fluid by a diaphragm. Diaphragms are actuated by hydraulic fluid between the piston and the diaphragm. Metering pumps are...

etering pumps allow the user to vary capacity as the process requires. All Milton Roy metering pumps permit adjustment whether the pump is running or not. With the exception of the Centrac (see Centrac drive), Milton Roy pumps are supplied with a manual micrometer for performing manual capacity adjustments. Depending on the type of drive mechanism and the application requirements, one of several capacity adjustment options can be supplied. > The manual micrometer can be used to adjust the metering pump's capacity anywhere between 0 and 100%. While not directly propor- tional to flow, this...

Milton Roy's diaphragm liquid ends are, by design, leakproof and durable. In some applications, however, added assurance is desired to protect the pump from hostile chemicals, or protect the process from contami- nation by hydraulic fluids. For these situations, Milton Roy has developed a highly reliable diaphragm rupture detection system.The system consists of two sepa-rate diaphragms, a hollow interme- diate ring, and a pressure gauge or switch. During the normal opera- tion, the two diaphragms are pushed tightly together and are separated only around their outside edge by the...

Proper metering pump system operation depends upon the selection of appropriate system components.Milton Roy offers high quality accessories to suit your application requirements. > Most piping systems require the use of an external safety valve to protect the piping from over-pres- sure. Diaphragm pumps feature internal safety valves to protect the pump, but external safety valves are still recommended. Milton Roy pro- vides safety relief valves to match the operating pressures of all pumps we manufacture. Standard safety relief valves are available in specialty steel, 316 SS, alloy 20,...

ilton Roy's Streaming Current Detector (SCD) is used to monitor and control coagulants in water or wastewater treatment. The SCD is an on-line instrument, therefore consistent effluent quality is assured.In addition to water and wastewater treat-ment, the SCD is widely used in paper making, petroleum, food, chemical, and other industries where close control of coagulant or charge altering chemicals are beneficial. > The Milton Roy Family of Streaming Current Detectors A broad line of electronic actuators, similar to those used on Milton Roy pumps, is available for control valve actuation...
