New Blackmer NPH and XH vane pumps feature 180° porting

Blackmer, part of PSG, has added the NPH and XH Series sliding vane pump models to its NP and X Series product families.

The XH Series pumps, which are designed to handle a wide range of non-corrosive and non-abrasive industrial liquids and petroleum products, while the NPH Series pumps are well-suited for handling viscous or shear-sensitive fluids.

Both pumps feature the same performance characteristics as the NP and X Series models and are available in 51 mm, 64 mm, 76 mm, and 102 mm sizes.

The NPH and XH Series pumps allow the user to choose between 90° and 180° porting.

Not all pumps have the capability for 180° 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.

An internal relief valve in both pump models protects them against excessive pressures, and a symmetrical bearing support further extends pump life.

The pumps feature a smaller motor for less operational costs while still providing high volumetric efficiency.

A high suction-lift capability makes NPH and XH pumps suitable for pumping from underground tanks, bulk-plant service, and aircraft refuelling.

The pumps are self-priming and capable of dry-running.

Their unique sliding vane method of operation results in high-level performance, energy-efficiency, and low maintenance costs.
