Pump Casings

Pump Casings

A pump casing is the pressure-containing volute that the impeller runs in; when one cracks, erodes or corrodes through, replacing the casing is far cheaper than replacing the pump. This collection holds Goulds 3175 casings (6x8-14, 14x14-18, 14x14-22), Goulds 3196 casings (1x1.5-6, 1x2-10, 2x3-13), a Flowserve 2469A casing, and the complete Goulds 3175, 3196, 3180 and 3700, Sulzer APT, Worthington FRBH, Durco Mark 3 and Summit 2196 pumps whose casings are also sold as a unit. Materials are 316SS, ductile iron, CD4MCu and Hastelloy C.

Match by pump model, size, material and the casing part number where cast into the flange. Rebuilt and used casings are inspected and photographed as-is, with the 30-day money-back guarantee. Casings ship LTL on a skid with freight arranged. Request a quote for a size not listed; Goulds casings are sourced regularly.

What does 'rebuilt' mean at DWP?

A rebuilt unit has been disassembled, inspected, had worn parts replaced and been tested before it goes on the shelf. It is covered by the same 30-day return policy as everything else we ship. 'Used' means as removed from service: we photograph the nameplate and note the condition, but the unit has not been through the shop.

Can I order with a PO or tax-exempt?

Yes. Purchase orders and tax-exempt certificates are accepted. Request a quote with the unit and quantity, and we return a formal quote your procurement team can attach to the PO.

What if the unit I need isn't listed?

Tell us the model, size and what it does. We source through a dealer, factory and surplus network and quote price and lead time within 24–48 hours. That includes obsolete and discontinued equipment.
