GPN 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, motors are 4 pole or 6 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 a patented oil lifter, for positive seal lubrication in any operating position; the spiral shape minimizes clogging. 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 internal overloads, enabling simple installation and direct connection to the power supply.
All models are supplied with 20 metres of heavy duty rubber power cable although IDS (individually screened cable) is available, at an extra cost, on all models, for quarry and mining applications. Each model is supplied with a hose connector in cast iron.
