B85Hx80/1P-SC-M 4x1 1/4"&28U

The B85Hx80/1P-SC-M 4x1 1/4"&28U is a 80-plate build of the SWEP B85. Its H plates are the high-theta pattern - the choice when the leaving temperature is tight and the pump has head to spare. The /1P-SC fields read as single pass, with 316/316L stainless steel plates and a copper braze. The closing M is the pressure class: up to 45 bar at 135 C, fatigue tested. Connections are listed as 4x1 1/4"&28U, 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 80-plate unit comes to about 13.0 kg (28.7 lb) dry. The frame is published to 17 m3/h (74.85 GPM) - a port limit rather than a design flow. Check the connection field separately from the plate count: two units can be consistant in every other field and still not pipe up.
