B56Hx140/1P-SC-Y 4x2 1/2"(54)

Part number B56Hx140/1P-SC-Y 4x2 1/2"(54) is the SWEP B56 frame carrying 140 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 /1P-SC fields read as single pass, with 316/316L stainless steel plates and a copper braze. It is catalogued with 4x2 1/2"(54) connections. The B56 plate pack measures 525 x 243 mm (20.67 x 9.57 in) on 430 x 148 mm port centres, and by SWEP's published weight formula a 140-plate unit comes to about 58.8 kg (129.6 lb) dry. Maximum flow for the frame is 76.2 m3/h (335.50 GPM); that is a ceiling for the ports, not a duty point. Use this designation as the reference on a quote request; nothing more is needed until the duty itself changes.
