ABSTRACT:
A peristaltic pump, in particular for pumping concrete, cement, and other mixtures containing liquid. The pump has a hose having layers of helically wound reinforcing threads embedded in the wall thereof. The angle of pitch of the windings in one layer is opposite to that in the other layer. The hose is fastened at the delivery end, and the angle of crossing, opening in the longitudinal direction of the hose, between the windings in the different layers is larger than the equilibrium angle.
