B16Hx90/1P-SC-S 4x1 1/4"(45)

The B16Hx90/1P-SC-S 4x1 1/4"(45) is a 90-plate build of the SWEP B16. 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. Connections are listed as 4x1 1/4"(45), in port order. The B16 plate pack measures 376 x 119 mm (14.8 x 4.69 in) on 320 x 63 mm port centres, and by SWEP's published weight formula a 90-plate unit comes to about 12.3 kg (27.1 lb) dry. The frame is published to 16.9 m3/h (74.41 GPM) - a port limit rather than a design flow. If the duty has changed since the original equipment went in, send the flows and both inlet conditions and we will confirm whether this configuration still fits.
