The industrial pumps of the NV series are characterized by high operational reliability and their tried-and-tested design. The proven design ensures maintenance-free operation and a long service life. The pumps are ideal for pumping clean or slightly contaminated media such as cutting oils, cooling lubricants, hydraulic oils, lubricating oils, motor oils, gear oils, kerosene, petroleum, glycol, heating oils, solvents, bitumen, additives, fuels, heavy oils, (bio- ) Diesel, but also thermal oils and vegetable oils. This makes the series suitable, for example, for machine tools, power plants or drying systems and much more.

* To ensure the pump is working properly, the pipes must be scaled according to the principles of fluid dynamics by calculation of line according to the local requirements.
The pump or device connection gives no indication of the relevant size of the pipe.
