Abstract

To control rate of liquid flow, particularly dyebath turnover utilising a reverse valve (9), liquid is circulated in a circulating system using a pump motor set comprising a centrifugal pump (1) driven by an electric motor, which pump motor set has a relationship between motor current and liquid flow rate which is both substantially linear and significantly inclined, the rate of liquid flow being determined from the motor current consumed.
