PAGE 19 C 30HDN PUMP 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 The highly abrasive nature of concrete under pressure makes it extremely important that expendable wear components be inspected at regular intervals between jobs to prevent having to replace these items during a pour Experience has proved that inconsistency of batched concrete mixes and frequent moving of the line requires the operator to be readily available at all times during pumping to stop the pump and prevent abuse to the unit which may occur if unexpected blockages develop PUMP MIX GUIDELINES When ordering concrete be certain to advise the concrete supplier that you require a pump mix The Direct flo manifold will pump a wide variety of materials but certain basic principles must be followed to assure successful pumping as follows Generally speaking the washed concrete sand and 4 aggregate pea gravel should conform to A S T M standards in regard to sieve analysis Sands in som

20. 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 This spring cushion in conjunction with the cam profile produces and uninterrupted smooth flow of material under average pumping conditions The pumping cylinder Figure 7 retracts drawing the material past the ball A and filling the cylinder The compensator piston is pumping the material out to the nozzle and causing ball B to seat preventing the material from returning to the pumping cylinder intake HOPPER PUMPING PISTON INTAKE An automatic centrifugal clutch is installed to engage and disengage the pumping action without stopping or starting the engine The centrifugal clutch is set at 1100 R P M The engine idle speed is approximately 875 R P M therefore the clutch is completely disengaged at idle The throttle settings while pumping should always maintain an engine R P M high enough to prevent the clutch from slipping and burning the clutch lining The return spring which is installed on the rocker arm is installed to eliminate shock and stre
