Extra Large Comet Pumps
Similar in construction to the comet pumps, with the exception that the plunger is drilled and tapped to accept the threads of a hydraulic cylinder. Since these large comets require several tons of pressure to compact the material, a hydraulic press is recommended for their production. These pumps are sized so the finished comets can be directly shot from 3, 4, 5, and 6 inch mortars. This produces a truly spectacular sight. All extra large comet pumps come nituff coated.
Note: When ordering the 4½" or 5½" comet pumps, please allow at least six weeks for delivery since they are not kept in stock and must be made to order.
