Flowserve makes the Durco Mark 3 chemical process pump, the other ANSI B73.1 standard next to the Goulds 3196, and DWP keeps around 20 Flowserve and Durco units in stock. Mark 3 STD pumps run from 1.5x3-8 through 2K3x1.5-10, 2K3x1.5-13 and 4x6-13 in CF8M, CD4MCu and Durco alloy D4, including a Mark 3 self-priming unit; a Durco Mark II 4x3x10 and a GRP2 4x6-13 are alongside. Beyond ANSI pumps there are WDR and WDXR four-stage horizontal multistage pumps, an 8 FRBH 223 process pump at 425 ft head, a SMP2000 with motor, an E3 rotary gear pump, a Worthington 8LG-1 split case rotating element, a 2469A casing and stuffing box covers.
Conditions are new surplus, rebuilt and used; rebuilt units were disassembled, inspected, refitted and tested. All carry the 30-day money-back guarantee and ship LTL with freight arranged.
