Peristaltic pumps consists mainly of pump house, rotor, roller, idle roller, squeeze hose and driving unit. The squeeze hose is U-shape in pump house, when rotor drives roller to rotate, hose is deformed. After the roller rotate, the deformed hose recover by its elasticity. Thus th e negative pressure in this hose is generated, sucking slurries, and discharging through outlet under roller’s push, finally forms pressure conveying of slurries.
