Concrete mixer variable displacement piston pumps long lifetime
Variable displacement piston pumps basic introduction:
Mixer hydraulic pump is to convert the mechanical energy of power
machine into the pressure energy of liquid. The output flow can be
adjusted according to need is called variable pump, the flow can
not be adjusted is called fixed pump. Our mixer hydraulic pump is
variable displacement piston pump.
Mixer piston pumps performance and characteristics:
Series 20 axial piston variable displacement pumps are swash plate
design with variable displacement, and are intended for closed
circuit applications.
The flow rate is proportional to the piston pump input speed and
displacement.
The latter is infinitely adjustable between zero and maximum
displacement.
Flow direction is reversed by tilting the swash plate to the
opposite side of the neutral (zero displacement) position.
