B320LTHx120/1P-SC-S 4x2 1/2"

The B320LTHx120/1P-SC-S 4x2 1/2" is a 120-plate build of the SWEP B320LT. 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. The connection field reads 4x2 1/2". 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 120-plate unit comes to about 64.9 kg (143.2 lb) dry. The frame is published to 76.2 m3/h (335.50 GPM) - a port limit rather than a design flow. Where a nameplate is worn, the plate count and the connection sizes are usually enough to separate this build from its neighbours in the series.
