High-pressure pitot tube pumps
High head.
Low flow.
Application-led.
EHIK PUMP supplies single-stage pitot tube pump solutions for demanding high-pressure duties—and independent replacement reviews for Roto-Jet®-type applications.
Send a nameplate photo, datasheet or performance curve. We will identify the remaining data needed for review.

Operating conceptVelocity → static pressure
01Duty-point review
Selection begins with actual flow, head and suction conditions.
02Fluid-specific configuration
Materials and sealing are checked against the process liquid.
03Replacement assessment
Hydraulic and dimensional suitability is confirmed model by model.
Operating principle / 01
Pressure is created in one rotating stage.
A pitot tube pump is a centrifugal pump in which the rotating casing adds energy to the liquid. A stationary pick-up tube then converts velocity energy into static discharge pressure.
Actual performance depends on the complete operating conditions, liquid properties and pump configuration.
Rotor adds energy
Rotation accelerates the liquid toward the outer diameter.
Tube collects flow
The stationary pick-up tube intercepts the high-velocity liquid.
Pressure is recovered
Velocity energy is converted into static discharge pressure.
Replacement engineering / 02
Evaluating a Roto-Jet® pump replacement?
EHIK PUMP provides an independent technical evaluation for existing pitot tube pump installations. A direct drop-in replacement is never assumed: hydraulic performance, interfaces and materials are reviewed before a configuration is proposed.

Selected duties / 03
Where pitot tube technology fits.
Commonly considered where high differential head is required at relatively low flow. Final suitability is subject to engineering review.
Boiler feed & condensate
High differential head duties where suction conditions and temperature must be checked carefully.
↗Water & process injection
Controlled injection duties for water and compatible process liquids.
↗High-pressure cleaning
Central cleaning, spray and wash systems requiring steady high-pressure delivery.
↗Reverse osmosis feed
Application-based selection for membrane feed and related high-pressure water service.
↗Pulp & paper showers
High-pressure shower service for selected paper-machine applications.
↗Chemical process duty
Selected chemical and hydrocarbon services, subject to full materials and seal review.
↗Selection input / 04
The pump must fit the process.
Pressure and flow alone are not enough. Send the available data—even if some fields are still to be confirmed.

Technical notes / 05
Before you specify.
Direct answers to common project questions.
Can EHIK PUMP replace my existing Roto-Jet® pump?
It may be possible, but interchangeability cannot be assumed. We compare hydraulic performance, dimensions, interfaces, materials, sealing and driver data first.
Can you select from flow and discharge pressure only?
Only a preliminary review is possible. Suction conditions, liquid properties, temperature, materials and installation requirements are needed for final selection.
Is a pitot tube pump right for every high-pressure duty?
No. NPSHA, viscosity, vapor pressure, solids, corrosion, temperature and sealing limits must be reviewed for each application.
Can you quote from a nameplate photograph?
A nameplate helps identify the existing unit. A reliable proposal usually also needs the duty point, curve, datasheet and installation details.
