BX8THx40/1P-SC-S 4x3/4"&16

The BX8THx40/1P-SC-S 4x3/4"&16 is a 40-plate build of the SWEP BX8T. 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. Reading the string: /1P is single pass; -SC is 316/316L stainless steel plates joined with copper. The closing S is the pressure class: 31 bar at 155 C. Connections are listed as 4x3/4"&16, in port order. The BX8T plate pack measures 315 x 73 mm (12.4 x 2.87 in) on 278 x 40 mm port centres, and by SWEP's published weight formula a 40-plate unit comes to about 3.5 kg (7.8 lb) dry. The frame is published to 4 m3/h (17.61 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.
