High-pressure plunger pump:
It is the heart of the unit and is responsible for bringing the liquid to the desired level. There are different types of high-pressure pumps, e.g. plunger pumps, piston pumps or diaphragm pumps. What they all have in common is that they displace a liquid in some way. The pressure is then built up against a flow resistance or downstream consumers such as nozzles.
Electric motor or diesel engine:
The motor drives the pump and is usually connected to the pump via a belt drive, direct coupling or clutch. Electric motors are widely used, mobile systems are often powered by motors, especially when electrical power is not available. KAMAT pumps have an internal gearbox that reduces the drive speed to the required pump speed. This eliminates the need for a belt drive or external gearbox.
It allows the operator to control the pump unit, e.g. start and stop the pump, adjust the pressure and monitor the system performance. The control panel may include switches, gauges and other indicators, as well as an emergency stop switch.
Hoses and fittings, pipes:
These components transport the water from the pump to its destination, e.g. to a nozzle, spray gun or other tool. The hoses and fittings must be strong and durable enough to withstand the high pressure liquid flow.
Pulsation damper at the outlet:
Since the plunger pump delivers a discontinuous flow into the discharge line, the flow is often harmonised by a pulsation damper to reduce negative effects on the wear of downstream components. Valves and pressure relief devices: These components regulate the water flow and protect the system from overpressure. Pressure relief valves (safety valves), for example, open automatically to release excess pressure when the system reaches a dangerous level.
A pump unit may require a casing to dampen ambient noise and control the internal temperature of the unit, even in extremely hot or cold environments. Heating or cooling systems may be used to stabilise the temperature of the unit.
Tank or water source:
A pump unit requires a liquid source from which it can draw. This can be a tank or reservoir, a municipal water supply or any other liquid source that meets the requirements of the unit.
A device that stabilises the flow into the pump to minimise acceleration losses caused by the liquid source and prevent cavitation.
Overall, each component plays an important role in the operation of a high pressure pump unit and they must work together efficiently to deliver the desired high pressure fluid flow.
