Blackmer, a supplier of positive displacement pumps and reciprocating compressor technologies, has upgraded the 4-in. model of its NP Series sliding vane pumps with optional electric heating. The 4-in. model joins the previously upgraded 2.5- and 3-in. models, completing Blackmer’s 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. Blackmer will continue to offer jacketed heads for customers who need NP pumps with steam and hot-oil capabilities. Blackmer said its NP Series pumps are specifically designed to offer maximum versatility for handling a wide variety of clean, non-corrosive liquids, including fluids of varying viscosities and temperatures. These pumps have been designed to minimize shear and agitation while providing excellent self-priming and dry run capabilities.
