E5THx12/1P-SC-S 4xHOLE

This is the 12-plate E5T: SWEP designation E5THx12/1P-SC-S 4xHOLE. The H plate is the obtuse chevron: it gives the most heat transfer per plate and the most pressure drop, so it suits duties where approach temperature matters more than pump head. Reading the string: /1P is single pass; -SC is 316/316L stainless steel plates joined with copper. The closing S is the pressure class: 31 bar at 155 C. The connection field reads 4xHOLE. The E5T plate pack measures 192 x 73 mm (7.56 x 2.87 in) on 154 x 40 mm port centres, and by SWEP's published weight formula a 12-plate unit comes to about 0.8 kg (1.7 lb) dry. The frame is published to 4 m3/h (17.61 GPM) - a port limit rather than a design flow. Where a nameplate is worn, the plate count and the connection sizes are usually enough to seperate this build from its neighbours in the series.
