B85Hx24/1P-SC-M 4x1"&22U

Part number B85Hx24/1P-SC-M 4x1"&22U is the SWEP B85 frame carrying 24 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 M is the pressure class: up to 45 bar at 135 C, fatigue tested. It is catalogued with 4x1"&22U connections. The B85 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 24-plate unit comes to about 5.4 kg (11.8 lb) dry. Maximum flow for the frame is 17 m3/h (74.85 GPM); that is a ceiling for the ports, not a duty point. If any field on your nameplate differs from the string above, tell us which one; a single letter is relevant to both rating and fit.
