The Spectra range of progressive cavity pumps from ProMinent fluid controls are believed to be an ideal choice for accurate dosing of polymer solutions such as those produced by the company's Ultromat® series of two-chamber and three-chamber polyelectrolyte batching and dosing systems. For these applications, the Spectra series feature a stator made from Vitone®,a stainless steel rotor and a highly effective rotary mechanical seal, which reportedly keeps maintenance requirements to a minimum.
Said to be suitable even for metering flocculent solutions containing oil,the pumps provide a smooth metered flow at rates between 1.5 and 5,1001/h at back pressures of three bar. They can be supplied with motors with a manual gearbox or automatic gearbox. The automatic versions feature thermal overload protection for additional safety.
According to the manufacturers, these simple pumps can be readily integrated into the control system for the Ultromat. Flow is proportional to pump speed and, in addition, the progressive cavity principle of operation means that no inlet and outlet valves are required.
