Sliding vane pump moves product in asphalt-handling applications

The NP Series sliding vane pumps from Blackmer have been designed to easily and efficiently transfer product in asphalt-handling applications.

NP Series pumps are ideal for the transfer of raw products from storage into the refinery, and from process to process within asphalt operations, Blackmer said.

The new pumps have been designed to handle a wide variety of liquids at varying temperatures, pressures, and viscosities, the company added. They are available in five sizes, with port sizes from 1.5 to 4 in.

Each pump features flow rates from 5 to 500 gpm at operating temperatures up to 500 deg. F. There is an operational 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).

Blackmer manufactures positive displacement pumps and reciprocating-gas compressor technologies.
