X model positive displacement rotary pumps, part of the Iron Line of sliding vane pumps, utilize a unique sliding vane design to offer the best combined characteristics of sustained high level performance, energy efficiency, trouble-free operation and low maintenance cost. Also, the high suction lift capability of these pumps makes them especially suitable for pumping from underground tanks, bulk plant service and aircraft refueling.
Blackmer® X model pumps are available in 2-, 2.5-, 3- and 4-in flanged port sizes with capacities from 10 to 520 U.S. gpm (38-1,855 L/min). Cast-iron construction is standard on all models except the X4 model which is ductile iron construction. All models have external ball bearings isolated from the pumpage by mechanical seals. X model pumps feature a 90° porting orientation, while XH model pumps have a 180° porting orientation.
Blackmer fully Integrated Unit Assemblies are the pre-engineered and pre-designed drop-in pumping solution. These unit assemblies, include motor, gearbox, baseplate, coupling safety covers, and a XLW Sliding Vane Pump (2, 2.5, 3 & 4-inch size). No alignment required with these pre-configured fully Integrated Unit Assemblies as they are ready for immediate drop-in installation.
Features and Benefits
- Durable pumps for fast and quiet operation
- Latest 6-vane design contributes to reduced noise levels in the pumps
- Blackmer mechanical seal and ball bearing construction provide maximum reliability
- Symmetrical bearing support assures even loading and wear for long life.
- Adjustable relief valve protects pump against excessive pressures.
- External ball bearings are isolated from pumpage by mechanical seals to maximize bearing life and minimize contamination risk.
- Advantages of sliding vane technology:
- Unique sliding-vane pump design self-adjusts for wear to maintain flow rates
- Excellent self-priming and dry-run capabilities
- Sliding vane design provides sustained performance and trouble-free operation
- Easy maintenance: vanes can be easily replaced without removing the pump from the piping system
- High suction lift and line-stripping capabilities
- Low maintenance and low life-cycle costs
