NKZ models are three phase slurry pumps, in cast iron, with a built-in agitator to stir sand, bentonite and pulverized solids into suspension for pumping. Capable of pumping large volumes at high heads, motors are 4 pole for increased wear resistance, they have a generous solids capacity. Constructed in superior grade materials throughout, they give exceptional performance in harsh operating conditions. The hydraulic design features a double mechanical seal, with an oil lifter, for positive seal lubrication in any operating position. The spiral shape of the pump casing, an air and water channel around the motor and the air-release valve, all combine to provide smooth, anti-clog pumping. Maintenance is straightforward, with simple replacement of parts, without the need for special tools. High-performance motors feature thermal protection, enabling simple installation and direct connection to the power supply.
Special use options: IDS (individually screened cable) is available on most models (Please request a quotation)
