Note: Unit pictured is representative of standard unit and may not exactly depict p/n B85Hx50/1P-SC-M 4x1 1/4"&28U as shown on this page.
The B85Hx50/1P-SC-M 4x1 1/4"&28U is a 50-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. The connection field reads 4x1 1/4"&28U. 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 50-plate unit comes to about 8.9 kg (19.7 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 seperately from the plate count: two units can be consistent in every other field and still not pipe up.
