Case Study: Non-Metallic Sealless Pump Replaces Alloy 20 Pump in Sulfuric Acid Application

Sulfuric Acid: A highly corrosive liquid used in cleaning metal surfaces and as a chemical intermediate to manufacture others chemicals. Exposure to Sulfuric Acid and its emissions is known to be highly corrosive to skin, inhalation of these vapors can cause serious lung damage. Sulfuric acid has Government-Regulated exposure limits. Emissions of Sulfuric Acid, either from Mechanical Seals or other manufacturing processes, is a contributor to acid rain and its subsequent environmental damage. Use of Sealless Pumps is recommended.

The customer was using a metallic ANSI 3x2x6 in Carp. 20 material with a Viton/Tungsten Carbide mechanical single seal. They pump had repeated seal failures due to poor piping design (entrained air), run dry situations and gaskets leaking. Each year the customer spent a minimum of $4000 for spare parts and labor to repair each metallic pump. This does not account for the loss of production, their labor to remove the pumps from their system and the shipping costs. It was apparent that the L.C.C. (Life Cycle Cost) of this system was far too high.

What is L.C.C. ?

Iwaki LCCThe non metallic pump not only addressed the leaking seal costs and health/safety hazards, but it’s ability to handle entrained air & run-dry allowed the pump to perform great in a less-than-perfect system design. We are pleased to report the customer now has had 3 pumps in service for over 2 years with not one failure. The pumps run quiet with zero maintenance required. As each old pump fails, in goes a sealless Iwaki pump. Check out all of our non-metallic pump technology at iwakiamerica.com
