B320LTHx50/1P-SC-S 4x2 1/2"

Part number B320LTHx50/1P-SC-S 4x2 1/2" is the SWEP B320LT frame carrying 50 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. 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. Connections are listed as 4x2 1/2", in port order. The B320LT plate pack measures 525 x 243 mm (20.67 x 9.57 in) on 430 x 148 mm port centres, and by SWEP's published weight formula a 50-plate unit comes to about 34.7 kg (76.5 lb) dry. Maximum flow for the frame is 76.2 m3/h (335.50 GPM); that is a ceiling for the ports, not a duty point. 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.
