B16Hx30/1P-SC-S 4x1 1/4"(45)

This is the 30-plate B16: SWEP designation B16Hx30/1P-SC-S 4x1 1/4"(45). 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"(45) connections. 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 30-plate unit comes to about 5.1 kg (11.2 lb) dry. Maximum flow for the frame is 16.9 m3/h (74.41 GPM); that is a ceiling for the ports, not a duty point. Thermal performance depends on the duty as much as on the part number, so include the fluids if the unit is going into a new application.
