B120THx70/1P-SC-S 4x2"(54)

This is the 70-plate B120T: SWEP designation B120THx70/1P-SC-S 4x2"(54). 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 4x2"(54), in port order. The B120T plate pack measures 525 x 243 mm (20.67 x 9.57 in) on 456 x 174 mm port centres, and by SWEP's published weight formula a 70-plate unit comes to about 36.6 kg (80.7 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.
