B320LTHx100/1P-SC-S 4x2 1/2"

Part number B320LTHx100/1P-SC-S 4x2 1/2" is the SWEP B320LT frame carrying 100 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 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 100-plate unit comes to about 56.3 kg (124.1 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. 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.
