Blackmer® Adds NPH And XH Series Sliding Vane Pump Models To Its Product Portfolio

180-degree porting option differentiates pumps from competitive technologies

Blackmer NPH SeriesBlackmer®, part of PSG®, has added the NPH and XH Series Sliding Vane Pump models to its NP and X Series product families. Both the XH Series pumps, which are designed to handle a wide range of non-corrosive and non-abrasive industrial liquids and petroleum products, and the NPH Series pumps, which are ideal for handling viscous or shear-sensitive fluids, 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.


The feature that sets the NPH and XH Series pumps from the competition allows the user to choose between 90- and 180-degree porting. Not all other brands have the capability for 180-degree porting in all pump sizes, which gives the NPH and XH pumps a level of operational flexibility that gear pumps and other technologies do not possess.

BlackmerXH SeriesStandard features on both the NPH and XH Series pumps include an internal relief valve that protects against excessive pressures; a smaller motor for less operational costs; high volumetric efficiency; symmetrical bearing support for extended life; high suction-lift capability that makes them suitable for pumping from underground tanks, bulk-plant service and aircraft refueling; self-priming and dry-run capability; and the unique sliding vane method of operation that results in high-level performance, energy-efficiency, trouble-free operation and low maintenance costs.
