B8THx50

Part number B8THx50 is the SWEP B8T frame carrying 50 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. The B8T plate pack measures 317 x 76 mm (12.48 x 2.99 in) on 278 x 40 mm port centres, and by SWEP's published weight formula a 50-plate unit comes to about 4.6 kg (10.1 lb) dry. The frame is published to 4 m3/h (17.61 GPM) - a port limit rather than a design flow. Check the connection field separately from the plate count: two units can be consistent in every other field and still not pipe up.
