B16DWHx40/1P-SC-S 4x1"NPT

Part number B16DWHx40/1P-SC-S 4x1"NPT is the SWEP B16DW frame carrying 40 plates. Its H plates are the high-theta pattern - the choice when the leaving temperature is tight and the pump has head to spare. 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. The connection field reads 4x1"NPT. The B16DW plate pack measures 377 x 119.5 mm (14.84 x 4.70 in) on 329 x 72 mm port centres, and by SWEP's published weight formula a 40-plate unit comes to about 10.4 kg (22.8 lb) dry. The frame is published to 11 m3/h (48.40 GPM) - a port limit rather than a design flow. If the duty has changed since the original equiptment went in, send the flows and both inlet conditions and we will confirm whether this configuration still fits.
