RPG GTR

The GTR Pitot tube pump is a single-stage, ‘lowflow, high-pressure’ rotodynamic pump. The design concept behind the revolutionary Pitot tube pump is remarkably uncomplicated, with a rotating case using centrifugal force to accelerate liquids through a stationary Pitot tube. The result is a steady, pulsation-free, high-pressure stream achieved with relatively low operating speeds.

The simplicity of this true single-stage pump design practically eliminates maintenance. There are no packing glands, wear rings, throat or throttle bushings as in conventional centrifugal pumps. No complex pistons, rods, valves, springs, or sophisticated system controls of reciprocating pumps – these are all worries of the past.

Drive shaft bearings are isolated from liquid flow, protecting from washout and possible pump damage. Thousands of on-line applications throughout the world – millions of operating hours – have proven the durability and efficiency of this design. There is only one dynamic seal in the suction side of the pump. No high-pressure dynamic seal. This means superior performance, simpler operation, lower operating costs, reduced parts inventory and longer pump life.
