Pump ultra-gently, meter precisely and with a wealth of applications.
The eccentric screw pump Spectra has been designed for the transport of polymer solutions with a viscosity of up to 5,000 mPas. It is low-maintenance and can even be used if polymer solutions containing oil are to be metered.
The pumps are equipped with gear motors and external fans and can be operated via an external frequency converter. Protect the pump from running dry.
