B18Hx100/1P-SC-U 4xS28.58&W35.1

Part number B18Hx100/1P-SC-U 4xS28.58&W35.1 is the SWEP B18 frame carrying 100 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 U is the pressure class: 64 to 140 bar. Connections are listed as 4xS28.58&W35.1, in port order. The B18 plate pack measures 377 x 119.5 mm (14.84 x 4.7 in) on 329 x 72 mm port centres, and by SWEP's published weight formula a 100-plate unit comes to about 29.1 kg (64.1 lb) dry. The frame is published to 9 m3/h (39.63 GPM) - a port limit rather than a design flow. Where a nameplate is worn, the plate count and the connection sizes are usually enough to seperate this build from its neighbours in the series.
