B85Hx34/1P-SC-M 4x1"(20)

Part number B85Hx34/1P-SC-M 4x1"(20) is the SWEP B85 frame carrying 34 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. Reading the string: /1P is single pass; -SC is 316/316L stainless steel plates joined with copper. The closing M is the pressure class: up to 45 bar at 135 C, fatigue tested. It is catalogued with 4x1"(20) 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 34-plate unit comes to about 6.7 kg (14.9 lb) dry. The frame is published to 17 m3/h (74.85 GPM) - a port limit rather than a design flow. A like-for-like order needs only this string; we recommend adding the fluids and flows where the system has been altered.
