A metering assembly includes a motor removably coupled to a pump using a flange clamp. An annular connection flange is provided at one end of the motor housing; and a cooperating annular connection flange is provided at one end of the pump housing. The connection flanges have opposed, mating end surfaces which are located in flush relation with each other. The flange clamp includes a pair of arcuate clamping arms which are pivotally supported at one end, and a locking member connecting the other, distal free ends of the arms together, and which can be manually tightened and untightened, so that the flange clamp can be easily located around and tightened down around the annular connection flanges of the pump and motor to create a mechanical face seal between the pump and motor.
