E8ASHx40/1P-SC-S 4x3/4"(20)

This is the 40-plate E8AS: SWEP designation E8ASHx40/1P-SC-S 4x3/4"(20). 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. Connections are listed as 4x3/4"(20), in port order. 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 40-plate unit comes to about 2.8 kg (6.2 lb) dry. The frame is published to 4 m3/h (17.61 GPM) - a port limit rather than a design flow. If any field on your nameplate differs from the string above, tell us which one; a single letter is relevant to both rating and fit.
