B26Hx50

This is the 50-plate B26: SWEP designation B26Hx50. 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. The B26 plate pack measures 376 x 119 mm (14.8 x 4.69 in) on 329 x 72 mm port centres, and by SWEP's published weight formula a 50-plate unit comes to about 7.1 kg (15.7 lb) dry. Maximum flow for the frame is 11.3 m3/h (49.75 GPM); that is a ceiling for the ports, not a duty point. Treat each side as an independent circuit when you ask for a quote: give both flows and what each fluid is.
