E8ASHx20/1P-SC-S 4x3/4"(20)

The E8ASHx20/1P-SC-S 4x3/4"(20) is a 20-plate build of the SWEP E8AS. Its H plates are the high-theta pattern - the choice when the leaving temperature is tight and the pump has head to spare. 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. It is catalogued with 4x3/4"(20) connections. The E8AS plate pack measures 315 x 74 mm (12.40 x 2.91 in) on 278 x 40 mm port centres, and by SWEP's published weight formula a 20-plate unit comes to about 1.6 kg (3.6 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.
