Steps in PlatingCleaning

Remove oils, dirt and other contaminants• Multi-stage process

• Dependent upon prior processing of metal parts

Cleaning tanks are the first tanks in the production sequenceProduction can be automated

• High percentage of manual operations in nearly all processes

ConvertingParts dipped into acid tanks after cleaning

Anodizing• 15% sulfuric acid / 85% water solution “opens” the surface• Converts aluminum to aluminum oxide

Color• Produces clear coating

• Colored coating achieved by dipping parts into a dye/color tank

Process Duration• Time in tank and temperature of fluid varies by application

Steps in Plating

SealingParts dipped into seal coat tanks after converting

• “Closes” the surface

Materials Used• Nickel fluoride

• Nickel acetate

Dry OffForced air containment area for drying

Pumps used in Plating FacilitiesDiaphragm pump applications

Supplying non-diluted acids from bulk tanks to the plating tanks• Polypropylene pumps for phosphoric acid @ a 80% solution

• Kynar pumps for sulfuric acid @ a 93% solution

Supplying caustics to the water treatment area• Polypropylene pumps for Sodium Hydroxide @ a 50% solution

Decanting the plating tanks• Polypropylene pumps for basic maintenance of the plating tanks require removal of up

to 30% of a tank, and replacing it with fresh material

• Pumps located near the tanks

Supplying lower volume chemicals to process tanks• Cleaning, converting, or color tanks

• Polypropylene pumps for soaps, dioxides, and nitric acids• One pump may be used to all of these materials

– Configured with elastomers for the most aggressive material.

Pumps used in Plating FacilitiesSupplying polymers for the water treatment areas

• Polypropylene or Kynar pumps typically utilized

How to use this chart:Step 1: Locate the required fluid flow rate along

bottom axis of chart.Step 2: Follow vertical line to the intersection with

the solid curve (A, B or C – based on your air inlet pressure).

Step 3: Follow to left axis to read fluid outlet pressure.

Step 4: From Step 2, follow vertical line up or down to the intersection with the dotted line(A, B or C – based on your air inlet pressure)then follow to right axis to read air consumption.

Example*With a Husky 2150 pump, to obtain 80 gpm (302.8 lpm)at approximately 50 psi (3.4 bar, 0.34 MPa), you willneed 100 psi (7.0 bar, 0.7 MPa) of air pressure. The airconsumption will be approximately 70 scfm.

Charter Steel, Saukville, WI, isone of the largest steelprocessing facilities in theMidwest. Processing wire, barand rod exceeds 500,000 tons,annually. A few years ago, themaintenance department inthe wire processing plant wasexperiencing an unacceptablehigh number of maintenanceproblems with the transferpumps in the facility. Thepumps were leaking, blowingdiaphragms and stalling. It wasa full time job for the plant’smaintenance department justto keep the pumps servicedand running.

“Our environment isextremely harsh on pumps,”explains Steve Hubing,Materials Coordinator. “Thevariety of fluids these pumpstransfer include corrosivechemicals, acids, sludge andwaste. It’s a very causticenvironment that requiresrugged, durable equipment.Our responsibility is to keepthese pumps operating. At thetime, we weren’t getting the

performance we needed out ofour pumps and ourmaintenance costs wereextremely high.”

In an effort to reduce pumpmaintenance and the expenseassociated with the problem,Charter Steel’s managementauthorized the maintenanceteam to study the pump issueand develop a plan to correctit.

“We discovered there weretwelve different styles andbrands of low pressurediaphragm pumps in the plant.Some of these pumps weredifficult to repair,” says JerryJacque, a member of themaintenance team. “Further-more, each style had differentparts and required differentrepair kits so we had to stockrepair kits for every pump. Wealso had to anticipate howmany kits we needed to stockbecause response from some ofthe suppliers was not alwaysprompt.”

One of the team’s firstrecommendations was to

standardize the pumpsthroughout the plant. To thisend, they ran comparison testson a variety of pumps fromdifferent manufacturers forseveral months. They monitoredperformance, maintenance,parts availability and cost.

“Our tests and researchindicated that Graco’s Husky™diaphragm pumps were themost reliable and easiest tomaintain,” says Jacque.

Initially, Charter Steelreplaced a batch of olderpumps that were causing themost trouble. Then they begana systematic conversion as theold pumps wore out andneeded to be replaced. Todaythere are approximately 50Graco Husky pumps in thefacility. The most common sizesare the 1 – 2-inch diaphragmpumps but they have a fewpumps as small as 1/4-inch.

The diaphragm pumps areused in pickling applications totransfer acid from bulk silos toprocess tanks; to transferrecovered used acid to bulktanks and acid regenerationsystems; in waste waterapplications to pumpwastewater from the cleaninghouses to the wastewatertreatment plants; and in achemical reprocessingapplication that features a 1/4-inch Husky pump with a GracoCycleFlo™ Controller thatmeters phosphate replenishers.

“That about takes care ofall our low pressure pumpingapplications,” says Hubing.

“Our most notable savingsis the reduction in thenumber of repair kits andparts we stock,” says Jacque.“Many of the repair kits canbe used for different modelsof Husky pumps so we’restocking fewer parts. In fact,we’ve reduced the number ofparts and repair kits we stockby 80%. We’ve saved over$200,000 in parts.

“The Husky pumps arerugged too, so we don’t havethe number of repairs weused to have. If maintenanceis required on the Huskypumps, it’s a lot easier. Wecan rebuild a Husky pump inabout half the time it took usto rebuild a competitivemodel. And the design of theHusky pumps is simple so ifwe only have to replace aseal or balls we don’t have totear down the whole pumplike other units.”Hubing gives credit to hislocal Graco distributor for hispart in the program’s success.
