B25THx20/1P-SC-S 4x1"&22U

The B25THx20/1P-SC-S 4x1"&22U is a 20-plate build of the SWEP B25T. 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 4x1"&22U. 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 20-plate unit comes to about 5.7 kg (12.5 lb) dry. The frame is published to 9 m3/h (39.63 GPM) - a port limit rather than a design flow. Treat each side as an independent circuit when you ask for a quote: give both flows and what each fluid is.
