Select correctly High-pressure pump
Từ định nghĩa, dải thông số đến 3 bước chọn model — tất cả trong một mạch.
High-pressure pump (high-pressure piston pump) in plunger design uses reciprocating cylindrical pistons (plungers) inside cylinders, forcing fluid through check-valve assemblies to generate very high pressure (up to ~3,000 bar). Multi-plunger configurations (triplex/quintuplex) deliver uniform flow and durability for continuous operation.
Applications: high-pressure water jetting, waterjet cutting, hydro-demolition (concrete breaking), descaling, pipeline/vessel hydrotesting, and high-pressure hydraulics. Flow rate and pressure trade off against each other — select based on the specific operating point.
1
Define pressure & flow rate
Determine the working pressure (bar) and flow rate (l/min) for the application — pressure and flow trade off against each other, so the required operating point must be clearly established.
2
Select plunger configuration & drive
Triplex/quintuplex based on flow uniformity and power requirements; electric motor or diesel engine drive depending on available power source and mobility needs.
3
Select accessories & brand
Spray gun, nozzle, cutting head, safety valve, and pulsation dampener according to the application. Choose Kamat (Germany) with CO-CQ documentation; TKT engineers provide configuration consultation.
High-pressure plunger pump or centrifugal pump?
When very high pressure is required, a positive-displacement plunger pump is the appropriate choice; centrifugal pumps are suited to high flow rates at moderate pressure.
| Criteria | High-pressure plunger | Centrifugal |
|---|---|---|
| Very high pressure | Suitable (up to ~3,000 bar) | Limited |
| High flow rate | Moderate | Suitable |
| Jetting / waterjet cutting | Suitable | No |
| Flow uniformity | Pulsation dampener required | Smooth |
| Efficiency at high pressure | High | Low |
| Cost | Higher | Lower |

Questions frequently asked
It is a positive-displacement pump that uses reciprocating cylindrical pistons (plungers) in cylinders through check-valve assemblies to generate very high pressure (up to ~3,000 bar). Triplex/quintuplex configurations deliver uniform flow and durability for continuous operation.
Essentially they belong to the same family: a 'high-pressure piston pump' is a plunger pump — using a cylindrical piston (plunger) reciprocating to generate very high pressure. 'Plunger' is the technical term for the cylindrical piston in industrial high-pressure pumps; both terms refer to the same type of positive-displacement pump used for water jetting, waterjet cutting, and hydrotesting up to ~3,000 bar.
Depending on the model and configuration — industrial plunger pumps can reach pressures up to approximately 3,000 bar (some models higher). Pressure and flow rate trade off against each other; for specific figures see the brand page or contact TKT engineers.
Centrifugal pumps are efficient at high flow rates and moderate head; at very high pressures their efficiency drops significantly. Piston/plunger pumps (positive displacement) maintain high efficiency at high pressure and are therefore suited to water jetting, waterjet cutting, and hydrotesting.
Triplex has 3 plungers, quintuplex has 5 plungers. More plungers produce more uniform flow (lower pressure pulsation) and better load distribution, suitable for higher power and continuous duty.
Yes. Hydro-demolition uses high-pressure water jets to remove deteriorated concrete while preserving reinforcing steel — clean and with less vibration compared with mechanical breaking. A high-pressure plunger pump and specialised spray head are required.
Electric motor or diesel engine (for mobile site work). Select based on available power source, required power output, and mobility requirements.
