B25THx50/1P-SC-M 2x28U+2x1"&22U

Part number B25THx50/1P-SC-M 2x28U+2x1"&22U is the SWEP B25T 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. The /1P-SC fields read as single pass, with 316/316L stainless steel plates and a copper braze. The closing M is the pressure class: up to 45 bar at 135 C, fatigue tested. Connections are listed as 2x28U+2x1"&22U, in port order. The B25T plate pack measures 526 x 119 mm (20.71 x 4.69 in) on 479 x 72 mm port centres, and by SWEP's published weight formula a 50-plate unit comes to about 11.0 kg (24.3 lb) dry. The frame is published to 9 m3/h (39.63 GPM) - a port limit rather than a design flow. If the flow on either side would exceed the published ceiling, the answer is a larger frame, not more plates on this one.
