Pumps (English) - pulsationsfreie einstufige Hochdruckpumpe high pressure pul

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 wash-out 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.

Only one Suction Mechanical Seal, no Pressure Seal. This means superior performance, simpler operation, lower operating costs, reduced parts inventory and longer pump life.

The basic concept behind the DBIC Pitot-Tube-Jet Pump is remarkable simple. The pump consists of two basic working parts, the stationary pick-up tube and rotating rotor. Liquid enters the manifold and passes into the rotating case where centrifugal force causes the liquid to accelerate and enter the rotor under pressure as it jets into the pick-up tube. The liquid flows through the pick-up tube and is discharged.

It should be noted that the only wetted contacting parts in the single stage DBIC Pitot-Tube-Jet Pumps are the mechanical seal faces which operate under suction pressure only. This eliminates the performance deterioration, possible seizure and maintenance costs incurred by multistage pumps with wear rings, balancing discs, interstage bushings, etc.

The DBIC Pitot-Tube-Jet Pump runs at relatively low speeds compared with high speed pumps with a resultant lower noise level.

A pitot pump offers distinct benefits in comparison with multi-stage and high speed centrifugals as well as positive displacement pumps which have been formerly used to develop pressures up to 200 bar, 8.000 rpm.
