Description

Blackmer X and XH Series sliding vane pumps are positive displacement rotary pumps for the loading, unloading, blending and transfer of clean, thin liquids. The sliding vane design self-adjusts for wear, so the pump holds its rated flow over a long service life instead of falling off the way a fixed-clearance rotary pump does. High suction lift and line stripping make these pumps well suited to underground tank service, bulk plant transfer, terminal loading and aircraft refueling.

This page covers the 2 inch through 4 inch models: capacities from 10 to 528 GPM, differential pressure to 125 PSI, viscosity from 0.2 to 4,250 cP, and temperatures from -25 F to 300 F. All models use external ball bearings isolated from the pumped liquid by a Blackmer single mechanical seal, an adjustable internal relief valve, and a single ended keyed shaft.

Two Porting Orientations, One Series

The X and XH models are the same pump platform with two different port arrangements, priced identically and sharing every option, kit and replacement part:

  • X models (X2B, X2.5B, X3E, X4B-N) have a 90 degree porting orientation: side inlet with a top outlet.
  • XH models (XH2B, XH2.5B, XH3E, XH4B) have a 180 degree porting orientation: side inlet with a side outlet directly opposite.

Choose the orientation that matches your piping run. The 2 inch, 2.5 inch and 3 inch models are cast iron; the 4 inch models (X4B-N and XH4B) are ductile iron. Blackmer's dimensional drawings, parts lists and kit tables refer to the X4B-N as the X4B.

Frequently Asked Questions

What are the main differences between the X and XH Series 2-4 Inch Sliding Vane Pumps?
The main difference lies in the porting orientation: X models have a 90-degree porting with a side inlet and top outlet, while XH models feature a 180-degree porting with side inlet and side outlet directly opposite. Both series share the same features, materials, and performance capabilities.
Can the Blackmer X and XH Series 2-4 Inch Sliding Vane Pumps handle viscous liquids?
Yes, the X and XH Series 2-4 Inch Sliding Vane Pumps are designed to transfer liquids with viscosities from 0.2 to 4,250 cP, making them suitable for viscous liquid transfer applications.
What maintenance parts are recommended for the X and XH Series pumps?
Recommended maintenance parts include complete maintenance kits for each port size and individual wear parts such as vanes, rotors, shafts, and mechanical seals. Regular replacement of these components helps ensure optimal pump performance and longevity.
