Pumps have 90 and 180 degree porting

Blackmer has added the NPH and XH Series Sliding Vane Pump models to its NP and X Series product families. The XH Series pumps are designed to handle non-corrosive and non-abrasive industrial liquids and petroleum products, and the NPH Series pumps are for handling viscous or shear-sensitive fluids. They feature the same performance characteristics as the NP and X Series models and are available in 2”, 2.5”, 3” and 4” (51 mm, 64 mm, 76 mm and 102 mm) sizes.

Users can choose between 90- and 180-degree porting. The 180-degree porting in all pump sizes gives the NPH and XH pumps a level of operational flexibility that gear pumps and other technologies do not possess, says the company.

Standard features include an internal relief valve that protects against excessive pressures, a smaller motor for less operational costs, high volumetric efficiency and symmetrical bearing support for extended life.
