Blackmer announce electric heating is available for vane range

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, lube oils, etc. Blackmer will continue to offer jacketed heads for customers who need NP pumps with steam and hot-oil capabilities.  

In order to accommodate the electric heating option, Blackmer has modified the NP2.5 and NP3 pump models by adding  two bosses to the gland area of the inboard head in order to allow drilling for two heat pots. The pumps also incorporate a thicker bearing cover to allow for the third heating pot to be located on the outboard side of pump. The heating pots are drilled and reamed to 12.5 mm and will accept any type of heating element that meets those dimensions. Special sleeve bearings, a stainless-steel relief-valve spring, high-temperature paint and high-temperature shaft packing will be included on any NP pump with the electric heating option.

Blackmer NP Series pumps can handle clean, non-corrosive liquids, including fluids of varying viscosities and temperatures.
