Selection Guide for Peristaltic Pumps a. Choosing hoses, you have to consider "Flow - see reference hose flow curve Chemical resistance - selection of hose material Fluid temperature - different materials have different temperature behavior. On the suction requirements - should choose high-performance hose. Hose life - Hose life varies depending on the hose's condition. "b. Choosing a pump head, you have to consider" Flow - choose the right pump head for the reference flow Hose change frequency - other than the BZ series, other Lange pump head products meet the requirements for a quick change hose Suitable channels Number - Multichannel pump head or pump head in series with multi-channel demand Chemical resistance - Consideration of pump head material when fluid overflows "c. Select drive, you have to consider" The higher the flow rate - the higher the drive speed , The greater the flow rate, select the appropriate drive by reference flow control form - fixed or adjustable speed, flow correction (to achieve precise control of flow), flow distribution (quantitative distribution), external control and other forms to choose from protection - According to the use of the environment, should consider the drive seal, dust, water requirements "
