MAYCO PUMP WARRANTY Mechanical Drive Models Hydraulic Drive Models MAYCO PUMP, hereinafter referred to as “Manufacturer’, warrants each new Mayco Pump sold by the manufacturer to be free from defects in material and workmanship, under normal use and service, for a period of one year after the date of delivery to the original retail purchaser.
SAFETY INSTRUCTIONS 1. Read the Mayco Owners Manual before moving or operating the unit. 17. Do not use worn out hoses or couplings; inspect daily. 2. Do not attempt to operate this pump without a thorough understanding of this technical manual. 18. Do not disconnect the hose couplings or nozzle while they are under pressure. Relieve the pressure by manually swinging the clamp arm latch handle to the first open position at the exhaust cone outlet. 3.
IMPORTANT HAND SIGNALS C-30HD — PARTS & OPERATION MANUAL — REV.
GENERAL INFORMATION The following operating principles and operating suggestions should prove helpful in the successful operation of your concrete pump. Your new “small line” concrete pump has been designed to give you many years of service when operated properly. A study of the following paragraphs is important to the successful operation of your new Direct-flo Concrete Placer. All concrete pumps require a high level of operator skill and more frequent service than most of the other construction equipment.
NOTE PAGE C-30HD — PARTS & OPERATION MANUAL — REV.
C-30HD — HOW IT WORKS The Mayco concrete pump has one main pumping piston which is valved by means of two ball checks. (A inlet, and B outlet.) The secondary piston is used as a compensator piston to smooth out the pulsations of a single piston action. Note: The compensator will not start operating until material is pumped into the line and back pressure develops. The compensator spring, which is installed on the compensator piston rod, deflects with each piston stroke.
C-30HD — HOW IT WORKS C-30HD — PARTS & OPERATION MANUAL — REV.
C-30HD OPERATING INFORMATION OPERATING SUGGESTIONS 1. A well-planned location of the pump and routing of the hose before starting a pour may save subsequent moves throughout the job. 2. Before concrete is discharged into the hopper, it is suggested that 3 to 4 gallons of water be sprayed into the hopper, followed by approximately 5 gallons of a creamy cement and water slurry (1/2 bag of cement to 5 gallons of water). This procedure lubricates the hose and prevents separation and blockages in the hose.
C-30HD OPERATING INFORMATION PUMPING TIPS AND TROUBLE SHOOTING 1. The effects of heat and excessive time on concrete: Hot concrete, commonly referred to as a hot load, is concrete that has been in the redi-mix truck in excess of 2 to 3 hours. On a hot day, this amount of time is even less. A brief explanation of why heat and time affect concrete: Concrete starts setting by drying up through a chemical reaction. The catalyst to this reaction is heat.
C-30HD OPERATING INFORMATION 7.10 Shake out around 2 feet of concrete before reconnecting hose to pump. After this is done, connect hose to pump and resume the pumping operation. 8. If it is necessary to wait 1/2 hour or more for another load of concrete, it is advisable to consider the factors affecting the concrete that is already in the pump and system. To prevent setting of the mix in the system: 1) how old is the concrete ? 2) is there an accelerator, calcium chloride, red label, etc.
C-30HD OPERATING INFORMATION 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.
C-30HD OPERATING INFORMATION PART B This section will explain the recommended procedure for using a sponge to clean out the lines. After completion of the pour, pump the remaining concrete in the hopper through the discharge line. Using a shovel, clean the sides of the hopper. (Note: The pump engine should be turned off, as explained in Part A of the Clean Up Procedure.) After the sides of the hopper have been cleaned, add a small amount of water to the remaining concrete in the hopper and hand mix.
CONCRETE MIX INFORMATION CONCRETE MIX DESIGNS-SCREEN ANALYSISTERMINOLOGY DEFINITIONS The following information has been prepared to assist in the selection of concrete mix designs in certain areas where the use of concrete pumps is a new industry. S.S.D.-Saturated Surface Dry: Meaning sand particles may be saturated with moisture but there is no free water on the surface.
CONCRETE MIX INFORMATION The following information has been extracted from actual testing laboratory reports. The purpose of this printing is only to help create a better understanding of the importance of uniform gradation and proportioning of materials which affect pumpability of concrete mixes. These weights and proportions illustrate that when the sieve analysis is ideal, the sand/rock ratio can be adjusted (65% sand 35% rock) and pumpability should be excellent.

SLUMP TEST PROCEDURE 1. To obtain a representative sample, take samples at three or more regular intervals throughout the discharge of the mixer or truck. DO NOT take samples at the beginning or end of the discharge. 2. Dampen the inside of the cone and place it on a smooth, moist, nonabsorbent, level surface large enough to accommodate both the slumped concrete and the slump cone. Stand on the “foot pieces” throughout the test procedure to hold the cone firmly in place. 3.
