E8ASHx34/1P-SC-S 4x3/4"(20)

This is the 34-plate E8AS: SWEP designation E8ASHx34/1P-SC-S 4x3/4"(20). 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. 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 34-plate unit comes to about 2.5 kg (5.4 lb) dry. The frame is published to 4 m3/h (17.61 GPM) - a port limit rather than a design flow. Depth is the one dimension that changes across the plate counts of a series, so measure the space behind the unit before moving to a larger pack.
