ST-45HRM CE CONCRETE PUMP— OPERATING PROCEDURES

19.VerticalPumping– Whenpumpingvertically up the side of a building, above 12.2 meters (40 feet), we would recom- mend the installation of steel pipe securely fastened at intervals as necessary to support the pipe. Ninety degree, long radius pipe sweeps should be installed at the top and bottom of the steel line.

Usea7.62meter(25ft.)hose,orshortsection,offthepump; and for the balance of the horizontal distance to the vertical line, use steel pipe.This type of installation has been satis- factory on many jobs being pumped in excess of 30 meters (100 feet) high. Line pressures are always less using steel pipe as compared to hose.

Whenpumpingvertically,usingallhose,itisrecommended nottogohigherthan7.62meters(50feet)withhose.Thehose shouldbetiedoffatintervalsof3meters(10feet),ifpossible. Special attention should be given when tieing the hose off at thetopasthehosewillhaveatendencytostretchwhenfilled with concrete.This will increase the possibility of a blockage at the point where the hose is tied off. To avoid this, a long radius of 90 degree elbow is recommended.The suggested place to tie off is on the hose, under the clamp.

NOTE

It is strongly recommended that

steel pipe be used on all vertical

nience.

20.Pulsation – A slight pulsation of the hose will always be noticeable near the pump. Excessive pulsation of the hose near the pump is normally due to higher than average line pressures caused by stiff, harsh mixes, or extremely long pumpingdistances.

Theuseof63.5mm(2-1/2”)I.D.hoseintheseextremecases reduces line pressures or the addition of slight amounts of water to the mix, if permissible, will permit easier pumping. The use of certain pumping admixtures may help.

Ifexcessivepulsationexistsinthehose,itisadvisabletouse burlap or some means of wear protection under the hose at pointswherethehosemaywearthroughtheoutercover;e.g. over forms, steel or sharp curbs.

21.Snap-Joint – When using Snap-Joint couplings with gas- kets to join hose, see that they are washed clean after each job.Keeping the hose ends clean (heavy duty) is very impor- tant for the best job setup.A thin coat of grease on the rubber gasket or dipping both coupling and gasket in water before coupling the hose will make for easier installation.

22.NewPumps–Allnewpumpsare‘waterpressuretested”atthe factoryThis procedure permits a thorough inspection of entire drive system and valving under simulated full load conditions. The pump owner can do the same by making an adapter to coupletotheendofthedischargecone:e.g.,theuseofastandard 51mm(2-inch)pipecapwitha 9.5mm(3/8")drilledholeinthe center, screwed on to the end of hinged cone or reducer at the pump.
