B25THx30/1P-SC-S 4x1"(45)

This is the 30-plate B25T: SWEP designation B25THx30/1P-SC-S 4x1"(45). 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. The connection field reads 4x1"(45). 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 30-plate unit comes to about 7.5 kg (16.4 lb) dry. The frame is published to 9 m3/h (39.63 GPM) - a port limit rather than a design flow. It is not neccessary to send drawings for a like-for-like replacement - the string above carries the whole build.
