B25THx100/1P-SC-S 4x1"(45)

Part number B25THx100/1P-SC-S 4x1"(45) is the SWEP B25T 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 4x1"(45), 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 100-plate unit comes to about 19.9 kg (43.8 lb) dry. Maximum flow for the frame is 9 m3/h (39.63 GPM); that is a ceiling for the ports, not a duty point. Treat each side as an independent circuit when you ask for a quote: give both flows and what each fluid is.
