B50Hx120/1P-SC-S 4x2 1/2"(54)

Part number B50Hx120/1P-SC-S 4x2 1/2"(54) is the SWEP B50 frame carrying 120 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. The closing S is the pressure class: 31 bar at 155 C. Connections are listed as 4x2 1/2"(54), in port order. The B50 plate pack measures 525 x 243 mm (20.67 x 9.57 in) on 441 x 159 mm port centres. It is not necessary to send drawings for a like-for-like replacement - the string above carries the whole build.
