Blackmer has upgraded the 4-inch model of its NP Series sliding vane pumps with optional electric heating. The 4-inch model joins the previously upgraded 2.5- and 3-inch models, completing the line of NP Series pumps with this option.
The electric heating option may be used in place of jacketed heads in order to provide pump heating for applications that normally require jackets, such as handling asphalt, bitumen, molasses, and lube oils. Blackmer will continue to offer jacketed heads for customers who need NP pumps with steam and hot-oil capabilities.
NP Series pumps are specifically designed to offer maximum versatility for handling a variety of clean, non-corrosive liquids, including fluids of varying viscosities and temperatures. These pumps have been designed to minimize sheer and agitation while providing superior self-priming and dry run capabilities.
