E6THx12/1P-SC-S 4xHOLE

This is the 12-plate E6T: SWEP designation E6THx12/1P-SC-S 4xHOLE. Its H plates are the high-theta pattern - the choice when the leaving temperature is tight and the pump has head to spare. The /1P-SC fields read as single pass, with 316/316L stainless steel plates and a copper braze. The closing S is the pressure class: 31 bar at 155 C. The connection field reads 4xHOLE. The E6T plate pack measures 210 x 73 mm (8.27 x 2.87 in) on 172 x 40 mm port centres, and by SWEP's published weight formula a 12-plate unit comes to about 0.9 kg (1.9 lb) dry. The frame is published to 4 m3/h (17.61 GPM) - a port limit rather than a design flow. It is not necessary to send drawings for a like-for-like replacement - the string above carries the whole build.
