Claim:
1. An apparatus for treating a pumpable material, the apparatus comprising: at least one chamber having a longitudinal length and comprising a first conductive surface, a second conductive surface opposing the first conductive surface, a first end at one end of the at least one chamber, and a second end at another end longitudinally opposing the first end of the at least one chamber, the first end and the second end each comprising an opening to allow the pumpable material to pass through the chamber in a direction along the longitudinal length of the at least one chamber, the opening of the first end for the pumpable material being at a first position, the opening of the second end for the pumpable material being at a second position, the first position being nearer the first conductive surface than the second position, and the second position being between the first conductive surface and the second conductive surface; and a channel for allowing pumpable material to be transferred from the first end to the second end of the chamber so that the pumpable material flows along the longitudinal length of the at least one chamber; wherein the at least one chamber is configured to receive electromagnetic energy from a source, the electromagnetic energy creating an electromagnetic field between the conductive surfaces, the electromagnetic field being lower near the conductive surfaces; wherein the channel is passed through an opening in a bend, wherein a conductive sleeve that is larger than the channel extends from the opening in the bend, and wherein the length of the sleeve is at least a quarter wavelength of the electromagnetic energy.
