Contributed by: PumpScout Staff

Blackmer, a leading manufacturer of positive displacement pumps, centrifugal pumps, and compressors, has just introduced the NPH and XH Series of sliding vane pumps. The new pumps feature 180-degree porting, and they are the perfect addition to the pump manufacturer’s NP and X Series product families.

The XH Series is designed to handle many different products, including a wide range of non-corrosive and non-abrasive industrial liquids and petroleum. The NPH Series of pumps is ideal when it comes to handling viscous and shear-sensitive fluids. Both of these series of sliding vane pumps feature the same performance details as the rest of the pumps in the NP and X lines. The NPH and XH Series are available in 2, 2.5, 3, and 4 inch options.

One feature of the NPH and XH Series of pumps that is especially unique is the fact that users can choose between 90- and 180-degree porting. According to Blackmer, no other brand offers the capability for 180-degree porting in all sizes, which ultimately provides the NPH and XH pumps with more operational flexibility.

There are a number of additional standard features on both the NPH and XH Series of pumps that make them stand apart. They each include an internal relief valve which is able to protect against excessive pressures. A small motor is used in each pump that allows the user to save on operational costs. Each pump offers high volumetric efficiency, while symmetrical bearing support offers an extended life.

Additional features include high suction-lift capabilities, which makes the pumps suitable for underground tanks, bulk-plant service, and aircraft fueling, as well as self-priming and dry-run capabilities. The pumps even offer a unique sliding vane method of operation which allows them to provide a higher level of performance, energy efficiency, and trouble-free operation, all while saving on maintenance costs.
