The ECOTRON® series in modular design allows the adaption of the high pressure system to the individual needs of the customer. A wide range of options is available.
BASIC EQUIPMENT
The basic design of this high pressure pump includes hydraulic drive unit with oil/water heat exchanger, high pressure intensifier and accumulator. The operating pressure is continuously adjustable via manual valve between 50 and 400 MPa. All components are mounted on a base frame.
RELIABILITY AND AND SERVICE-FRIENDLINESS
Standard hydraulic components ensure a high level of safety in operation and user-friendliness. The design of the base frame follows best practices and guarantees easy access to all components.
OPTIMIZED HYDRAULIC SYSTEM
The hydraulic units used are characterized by highly dynamic controls. Use of a soft-switching hydraulic valve with specially designed control geometry guarantees extremely short switch-over times.
LONG LIFE EXPECTANCY
Oil filtering and cooling take place in a separate and constant oil circuit, driven by an integrated gear pump. The excellent oil quality this achieves has a positive influence on operational safety and the life expectancy of the whole hydraulic system.
AT THE CORE: PRESSURE INTENSIFIER
The high pressure components in the intensifier are characterized by a long life expectancy. Besides the special stainless steels developed specifically for this application, a large plunger diameter and a long stroke both help to achieve this. Thanks to the special flange design and externally accessible check valves, the intensifier is easy to maintain. Wearing parts like seals and check valves can be replaced quickly and easily.
REDUCTION OF PRESSURE FLUCTUATIONS
Depending on the flow rate of the pump, the integrated accumulator has a large volume of up to 2.49 liters. This reduces pressure fluctuations to a minimum and thus prevents wear on the high pressure system.
Following options are available :
PRESSURE ADJUSTMENT
Dual and electronic pressure adjustment is available as option. With the dual pressure system two different operating pressures (e.g. piercing and cutting pressure) are manually adjustable. The switch-over between both pressures is done internally and externally via digital signal. Electronic pressure control is done via proportional valve. With this option the working pressure is adjustable at the operating panel directly at the pump or via external analog signal.
OIL/AIR COOLER
As alternative to oil/water heat exchanger an oil/air cooler is available.
HIGH PRESSURE PUMPS SERIES ECOTRON® ARE CHARACTERIZED BY THE FOLLOWING FEATURES:
FEED WATER SUPPLY
The fitted pre-filtering unit with 5 µm and 1.2 µm filters guarantees optimumfeed water supply.
BOOSTER PUMP
If the feed water pressure is less than 0.3 MPa, an optional booster pump is available to increase the water pressure.
HIGH PRESSURE BLEED DOWN VALVE
This pressure release valve is installed within the high pressure line of the pump. The valve is activated via the stop button or the emergency stop circuit. In addition it can also be controlled externally, if needed for the piercing process with abrasive waterjet.
PUMP CONTROL
Depending on the pressure control system (manual and dual or proportional) two different versions for the electric control of the high pressure pump are available. The switch box is directly mounted at the base frame of the pump. The control is done via the integrated panel. All warnings and monitoring functions are displayed in clear text. Important functions are remotely controllable and the connection to an external control is possible
via interface.
SOUND INSULATION
A sound insulated housing is available as option. On request, multiple-voltage and multiple-frequency motors are available for ECOTRON® series high pressure pumps.
