The Etanorm SYT heat-transfer-liquid pump features a new VenJet venting device, which ensures that the low-boiling fractions or water vapor do not get near the plain bearing or mechanical seal. The new pump features several design improvements. For example, the discharge cover has four bars that make it rigid in the area of the heating barrier. As a result, they reduce the heating up of the bearing bracket, thus keeping the area well below the critical temperature range, despite the presence of hot fluids. The SYT is also available with a double mechanical seal in tandem arrangement with quench supply. On this design, the bearing bracket has an intermediate wall to create a separate quenching space within the mechanical seal chamber. — KSB AG, Frankenthal, Germany
