B16Hx20

Part number B16Hx20 is the SWEP B16 frame carrying 20 plates. 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 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 20-plate unit comes to about 3.9 kg (8.6 lb) dry. The frame is published to 16.9 m3/h (74.41 GPM) - a port limit rather than a design flow. Use this designation as the reference on a quote request; nothing more is needed until the duty itself changes.
