V80Hx30/1P-SC-S 16(27)+35.1(27)+2x1 1/4"&28U(27)

This is the 30-plate V80: SWEP designation V80Hx30/1P-SC-S 16(27)+35.1(27)+2x1 1/4"&28U(27). 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. The /1P-SC fields read as single pass, with 316/316L stainless steel plates and a copper braze. The closing S is the pressure class: 31 bar at 155 C. Connections are listed as 16(27)+35.1(27)+2x1 1/4"&28U(27), in port order. The V80 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 30-plate unit comes to about 8.4 kg (18.6 lb) dry. The frame is published to 16.9 m3/h (74.41 GPM) - a port limit rather than a design flow. Depth is the one dimension that changes accross the plate counts of a series, so measure the space behind the unit before moving to a larger pack.
