The NP Series pumps can meet the needs of asphalt-handling applications because they have been designed for the handling of a wide variety of liquids at varying temperatures, pressures and viscosities. This allows the NP pumps to offer versatility while sustaining a high-level of performance and trouble-free operation.
NP Series pumps are available in five sizes, with port sizes from 1.5ins to 4ins. They feature flow rates from 5 to 500 gpm (19 to 1,893 lpm) at operating temperatures up to 500degF (260degC), with an optional jacketed pump head for high-temperature operating atmospheres. They can handle viscosities ranging from 30 to 20,000 ssu (4,250 cP) at differential pressures up to 150 psi (10.3 bar) with standard construction, while an adjustable relief valve protects against excessive operating pressures. With optional materials, maximum viscosities can go to 100,000 ssu (22,000 cP) and differential pressures up to 200 PSI (13.8 bar).
