B80Hx40/1P-SC-M 2x35.1+2x1 1/4"&28U

Part number B80Hx40/1P-SC-M 2x35.1+2x1 1/4"&28U is the SWEP B80 frame carrying 40 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 M is the pressure class: up to 45 bar at 135 C, fatigue tested. The connection field reads 2x35.1+2x1 1/4"&28U. The B80 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 40-plate unit comes to about 9.2 kg (20.2 lb) dry. Maximum flow for the frame is 16.9 m3/h (74.41 GPM); that is a ceiling for the ports, not a duty point. For a new duty, send the inlet temperature on each side and the flows, and we will say immediately whether this plate count is the right one.
