B28Hx36/1P-SC-S 4x1 1/4"(27)

The B28Hx36/1P-SC-S 4x1 1/4"(27) is a 36-plate build of the SWEP B28. 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 S is the pressure class: 31 bar at 155 C. It is catalogued with 4x1 1/4"(27) connections. The B28 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 36-plate unit comes to about 8.0 kg (17.6 lb) dry. The frame is published to 16.9 m3/h (74.41 GPM) - a port limit rather than a design flow. 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.
