B35Hx50/1P-SC-S 4x1 1/2"NPT

Part number B35Hx50/1P-SC-S 4x1 1/2"NPT is the SWEP B35 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 S is the pressure class: 31 bar at 155 C. It is catalogued with 4x1 1/2"NPT connections. The B35 plate pack measures 393 x 243 mm (15.47 x 9.57 in) on 324 x 174 mm port centres, and by SWEP's published weight formula a 50-plate unit comes to about 22.9 kg (50.5 lb) dry. The frame is published to 27.4 m3/h (120.64 GPM) - a port limit rather than a design flow. If any field on your nameplate differs from the string above, tell us which one; a single letter is relevant to both rating and fit.
