B85Hx140/1P-SC-M 4x1 1/4"&28U(27)

The B85Hx140/1P-SC-M 4x1 1/4"&28U(27) is a 140-plate build of the SWEP B85. 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. Connections are listed as 4x1 1/4"&28U(27), in port order. 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 140-plate unit comes to about 21.2 kg (46.8 lb) dry. The frame is published to 17 m3/h (74.85 GPM) - a port limit rather than a design flow. Use this designation as the reference on a quote request; nothing more is needed until the duty itself changes.
