B35Hx40/1P-SC-S 4x1 1/2"

This is the 40-plate B35: SWEP designation B35Hx40/1P-SC-S 4x1 1/2". 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 1/2". The B35 plate pack measures 393 x 243 mm (15.47 x 9.57 in) on 324 x 174 mm port centres, and by SWEP's published weight formula a 40-plate unit comes to about 19.5 kg (43.0 lb) dry. The frame is published to 27.4 m3/h (120.64 GPM) - a port limit rather than a design flow. Use this designation as the reference on a quote request; nothing more is needed until the duty itself changes.
