Clean UP Procedure Part a | Multiquip C-30HD specification

12.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 pumping distances. The use of 2 1/2” I.D. hose in these extreme cases 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.

If excessive pulsation exists in the hose, it is advisable to use burlap or some means of wear protection under the hose at points where the hose may wear through the outer cover; e.g. over forms, steel or sharp curbs.

13.If the cam roller does not ride on the cam profile smoothly, it may be caused by insufficient line back-pressure; e.g., a wet mix with only 50 feet of hose. Add more hose as necessary. It can also be caused by cavitation or the passing of over- sized aggregates through the valving, causing it to skip.

14.When using Snap-Joint couplings with gaskets to join hose, see that they are washed clean after each job. Keeping the hose ends clean (heavy duty) is very important 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.

15.All new pumps are “water pressure tested” at the factory before shipment.This procedure permits a thorough inspection of entire drive system and valving under simulated full load conditions. The pump owner can do the same by attaching an adaptor to couple to the end of the discharge cone; e.g., the use of a standard 2” pipe cap with a 3/8” hole drilled in the center , screwed on to the end of the hinged cone or reducer at the pump. Fill the hopper with water after making sure that all sand and rock have been removed from the manifold. Operate the pump at full throttle and the 3/8” diameter hole restriction will create sufficient back-pressure to make a thorough inspection of all moving parts.

16.Before starting the pumping operation, the following check list procedure should be followed:

1.Check the engine oil.

2.Check the oil reservoir of the lubrication system to make sure that it is full.

3.Inspect the chain and belt adjustment.

4.Check the cam oiler.

5.Start and run the engine a minimum of five minutes before starting the pumping operation.

Note: When the redi-mix truck arrives, it is always a good idea to check the concrete ticket and make sure you have the proper mix design.

CLEAN UP PROCEDURE

PART A

1.Ensure that there is no blockage in the hose and line (See Page 15, Para. 6) or in the manifold (See Page 15, Para. 7). If a blockage exists, clear it as it dictates how the machine will pump the next time it is used. At the end of every pour, or because of long delays during a pour, the pump and delivery system must be thoroughly cleaned by removing all concrete material.

2.Proper wash out of all materials or build up within the pump manifold and hoses following the pumping operation will prevent problems when starting the next job. After completion of the pour, pump the remaining concrete in the hopper through the discharge line.

3.Note: To avoid the possibility of separation during clean-up, do not pump the concrete below the inlet ball in the hopper. It is best to leave approximately 3 to 4 inches of concrete above the inlet ball.

4.Turn the pump engine off before filling the hopper with water. Engine vibration at idle may “separate” material in the hopper, causing jamming in manifold when pumping is resumed.

5.Fill hopper with water and resume pumping. The water will push the concrete through the line. When the water runs clear at the end of the hose, disconnect lines and shake out all the sand and sediment so the lines will be clean for the next pour.

6.It is important that the hinged discharge cone on the pump manifold be opened and all remaining concrete (rock and sand) be thoroughly washed out.This must be done after each job to prevent concrete build up in the discharge manifolds and 3” discharge elbow.
