B28Hx96/1P-SC-S 4x1 1/4"(27)

Part number B28Hx96/1P-SC-S 4x1 1/4"(27) is the SWEP B28 frame carrying 96 plates. 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 4x1 1/4"(27), in port order. The B28 plate pack measures 526 x 119 mm (20.71 x 4.69 in) on 470 x 63 mm port centres, and by SWEP's published weight formula a 96-plate unit comes to about 17.8 kg (39.3 lb) dry. The frame is published to 16.9 m3/h (74.41 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.
