E8LASHx40/1P-SC-S 4x3/4"(20)

Part number E8LASHx40/1P-SC-S 4x3/4"(20) is the SWEP E8LAS frame carrying 40 plates. 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. 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 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 40-plate unit comes to about 2.8 kg (6.1 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 relevent to both rating and fit.
