Sulzer & Ahlstrom Pumps
Shop All Sulzer & Ahlstrom Pumps
Sulzer, and the Ahlstrom line it absorbed, built the end-suction stock pumps that run most North American paper mills, which is why DWP sees so many of them. In stock are APT series pumps from APT21-3 (3x4-8) through APT32, 33, 41, 43, 44 and 53 up to APT61-24 (24x24-28) in 316SS, most with closed or semi-open impellers; an MCE82-300 medium consistency back pull-out; an Ahlstrom MPP-10-P1 medium consistency pump; a NPT42-6 6x8-14 process pump at 1500 GPM; and an AM25-15FS chemical mixer. Parts include 814 CHO casings with impellers, APT stuffing box covers, wear plates and suction side plates, and shaft sleeves.
Conditions are new surplus, rebuilt and used. Rebuilt Sulzer pumps were disassembled, inspected, refitted and tested; used pumps were inspected and photographed as-is. All carry the 30-day money-back guarantee and ship LTL on a skid.
For an APT size or an Ahlstar unit we do not list, request a quote with the nameplate; Sulzer stock pumps come through the mill surplus network regularly. Closing a paper machine? We buy Sulzer and Ahlstrom surplus.
