GD Energy Products has created a perfectly-engineered system that will provide more useable energy than any other waterjetting product on the market. Each Multi-Blaster 450 Series unit includes a TX 450 pump with two fluid end options, a 475 HP diesel engine or electric motor, gearbox, pump filtration, fuel tank for diesel units, unit instrumentation and safety relief systems.

The new sectionalized fluid end design on the TX-450SB system allows for easy replacement of valves. The plungers, packing, and brass on this pump are also easily replaceable due to a larger working space in the well of the pump for easy access. The valves are soft-seated and which allow for “dirty water” from various sources.

The Horizontal “in-line” suction and discharge valves and seats eliminate intersection bores which can lead to premature fluid end failures at pressures above 15,000 PSI. Please contact your GD Energy Products authorized dealer for details.
