E8LASHx54/1P-SC-S 4x3/4"(20)

The E8LASHx54/1P-SC-S 4x3/4"(20) is a 54-plate build of the SWEP E8LAS. 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 4x3/4"(20). The E8LAS plate pack measures 316 x 74 mm (12.44 x 2.91 in) on 278 x 40 mm port centres, and by SWEP's published weight formula a 54-plate unit comes to about 3.6 kg (7.9 lb) dry. Maximum flow for the frame is 4 m3/h (17.61 GPM); that is a ceiling for the ports, not a duty point. 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.
