3.3 Description of the functions
This section is intended to help you understand the functions of the machine so that you can restrict
the field of the machine’s applications to suitable areas and avoid errors in operation.
3.3.1 Pump
K.C.P pumps are driven hydraulically through diesel engine powered fluid pumps. The delivery
pistons (4) are hydraulically linked together through the driving cylinders (5). They operate in a push-
pull mode. The returning delivery piston sucks the concrete in. At the same time, the advancing
delivery piston forces the concrete in. At the same time, the advancing delivery piston forces the
concrete sucked in previously into the delivery line through the pressure pipe or the transition door
(1).
The pump switches over at the end of the stroke. The transfer tube (2) swings over the full delivery
cylinder (3) and the delivery pistons (4) reverse their direction of movement.
Reverse stroke
Reversal of the delivery pistons’ (4) movement in the middle of the stroke management. The S-tube
(2) does not switch. The concrete is sucked back from the delivery line into the hopper.
Switchover
Reversal of the delivery pistons’ (4) direction in the middle of the stroke movement. The S-tube (2)
switches over. The concrete is still pumped without interruption. Switching over helps prevent the
formation of blockages.
