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 30 to 520 U.S. gpm (114-1,855 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.
