Back filling applications

Where thickened slurries need to be back-filled a NEMO® hopper pump is used. High pressure and capacity capabilities, coupled with low wear rates ensure reliable cost effective operation.

NEMO® SY, NEMO® BY, NEMO® BO and NEMO® SO

NEMO® progressive cavity pumps convey thickened slurry at high pressure.

Gland seal water

The high pressure capabilities of the NEMO® progressive cavity pump ensures that gland seal water can be safely supplied to critical glands at pressures of up to 50 bar and higher. The ideal combination of high pressure, lower flowrate pulsation free discharge ensures the ideal seal operating conditions.

NEMO® BY and NEMO® SY

NEMO® pump supplying gland seal water at 48 bar to centrifugal pumps.

Chemical dosing

For the dosing of all types of chemicals and additives the NEMO® pump is the ideal choice. With a flowrate directly proportional to the rotation speed the pump can accurately dose the required chemicals without wastage.

TORNADO® T2 Industrial Rotary Lobe Pumps

The TORNADO® T2 rotary lobe pump is a positive displacement pump. The pumping action is generated by the contra-rotation of two rotors within the pump chamber which are synchronised externally. The media enters the pump chamber through the inlet port and is carried around the chamber by the rotors to the outlet port where it is discharged.

NOTOS® Multi Screw Pump

The NOTOS® family has superior quality standards to meet the highest level requirements from our customers. The pumps are designed to work with low to high lubricant fluids, low to high viscosity, shear sensitive and/or chemically agressive media.
