B120THx30/1P-SC-M 2x42U+2x1 1/2"&35.1

The B120THx30/1P-SC-M 2x42U+2x1 1/2"&35.1 is a 30-plate build of the SWEP B120T. 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. The connection field reads 2x42U+2x1 1/2"&35.1. 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 30-plate unit comes to about 20.5 kg (45.1 lb) dry. The frame is published to 27.4 m3/h (120.64 GPM) - a port limit rather than a design flow. Check the connection field separately from the plate count: two units can be consistent in every other field and still not pipe up.
