I am designing and assembling a small laboratory scale reactor in an explosion proof environment. The design calls for two small reciprocating/rotating pumps for feeding in the raw materials. I have spec'd out adequate pumps from Fluid Metering Inc. that meet our needs, however they do not sell a pump/motor combination that meets the group C requirements. I am buying the "pedestal" drive module but need a motor to drive each pump head. The motor needs a minimum of 35 inch/ounces of torque and will need to run at most 100-150 RPM, but will need to be controllable down to very low RPMs. We will have a Modicom PLC which will need to vary the pumping rate based on the data from load cells, so the controllers need to be compatible. So far, the only motor I have found was from Moog, but their rating for Class 1, Div 1 was pending from Factory Mutual. Any suggestions on other motors available? PS: My budget does not allow for building/buying purged enclosures.
