A pump casing contains a special high elasticity and
resistance, which is flanged at both ends (connections).
The flanges are connected to the suction and
discharge lines of the system.
Within the casing is a rotor with two rollers at
opposite points about its centre line and mounted
on a shaft with bearings.
As a result of the rotor pivoting, the hose is totally
compressed by the rollers and the product within
The sucking action comes as the hose restores its
original cylindrical form after compression.
The hose's worn surface must be lubricated with
