B320HTHx140/1P-SC-S 4x2 1/2"

Part number B320HTHx140/1P-SC-S 4x2 1/2" is the SWEP B320HT frame carrying 140 plates. Its H plates are the high-theta pattern - the choice when the leaving temperature is tight and the pump has head to spare. 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 4x2 1/2" connections. The B320HT plate pack measures 525 x 243 mm (20.67 x 9.57 in) on 441 x 159 mm port centres, and by SWEP's published weight formula a 140-plate unit comes to about 67.8 kg (149.5 lb) dry. The frame is published to 61.7 m3/h (271.66 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.
