HIGH PRESSURE

Hydraulic Pressure Intensifiers – MP-2000 Series

The MP-2000 is an in-line pressure intensifier designed to be positioned in a low-pressure hydraulic system and will provide higher pressure exactly where needed (max. 2.000 bar). Having all the required high-pressure valves incorporated, the need for additional high-pressure components is minimized ensuring a cost-effective system. Controlling the high-pressure side is achieved by valves on the low-pressure side through the intensifier adding to safety. The intensifiers are offered with 4 different intensification ratios to meet most intensification requirements. The compact design ensures easy installation in new as well as existing hydraulic circuits. The MP-2000 is offered with a pilot operated check valve (POV) integrated, which allows the high-pressure side to be relieved through the intensifier. 

Key Features of the MP-2000:

  • In-line pressure intensifier, reciprocating type for continuous flow
  • Medium-high pressure and medium flow rate applications
  • Optional top plates are available for high pressure connections

MP-2000 Configurations:

  • MP-2000-XP: The MP-2000-XP is made for installation in smaller power packs, where a higher end pressure is required, for example, a bolt tensioner. It is designed for smaller high-pressure power packs up to 2,600 bar/37,700 psi. This model also features an extra HP port for gauge mounting.

    When the XP-intensifier is connected to P and T, it will automatically increase the supplied pressure proportionally to the required end pressure. For evacuation of the high-pressure side, a pilot operated check valve is integrated, and when activated, the flow from the high-pressure side is led through a separate side port directly to tank, where it will be cooled and filtered before being pumped back in the hydraulic circuit. 
  • MP-2100: The MP-2100 supports a higher maximum inlet flow up to 4 gpm (15 lpm) compared to the MP-2000’s 3.4 gpm (13 lpm), making it ideal for applications requiring greater flow efficiency.

Technical Data:

  • Inlet Flow:
  • MP-2000 and MP-2000-XP: up to 3.4 gpm (13 lpm)
  • MP-2100: up to 4 gpm (15 lpm)
  • Supply pressure: up to 2,900 psi (200 bar)
  • End pressure rating:

LOW/MEDIUM PRESSURE

Hydraulic Pressure Intensifiers – MP-C Series

The MP-C Series is a pressure intensifier specifically designed for Cetop/NG6 mounting.

Key Features of the MP-C:

  • Cetop/NG6 pressure intensifier, reciprocating type for continuous flow

MP-C Configurations:

  • Hydraulic stacking system applications (MP-CT): The MP-CT Series intensifier is made for installation in hydraulic stacking systems, where a higher end pressure is required for a specific job. Higher pressure is suppled through a separate female port G1/4″. The supply circuit will not be affected by the higher pressure and will not have influence on other functions in the chain. Using the MP-CT in a hydraulic system offers the advantage, that the system pressure can be kept as low as possible, as any higher pressure can be obtained where needed. This way pressure reduction in the whole system and energy wasting can be avoided.
  • No change of pressure in A & B ports, separate port for high pressure
  • Main difference between MP-C and MP-CT is the CT’s external port for the intensified pressure, typically utilized for cases where intensified pressure exceeds the rating of the Cetop DO3/NG6 mounting interface

Technical Data:

  • Inlet Flow: up to 4 gpm (15 lpm)
  • Supply pressure: up to 2,900 psi (200 bar). The supply circuit will not be affected by the higher pressure and will not have influence on other functions in the chain. 
  • End pressure rating:
  • MP-C: 290 – 7,250 psi (20 – 500 bar)
  • MP-CT: 290 – 11,600 psi (20 – 800 bar)
  • The end pressure is dependent on the ratio and is always proportional with the supplied pressure.
  • Multiple intensification ratios
  • Integrated high pressure valves, including pilot operated check valve (POV):
  • MP-C: Allows the high-pressure side to be evacuated back to tank through the intensifier
  • MP-CT: Operated by a directional valve on the supply side and will activate the high-pressure side to tank
  • Weight:
  • MP-C: 5.94 lbs (2.7 kg)
  • MP-CT: 5.28 lbs (2.4 kg)

LOW/MEDIUM PRESSURE

Hydraulic Pressure Intensifiers – MP-T Series

The MP-T Series is an in-line pressure intensifier designed to be positioned in a low-pressure hydraulic system and will provide higher pressure exactly where needed (max. 11,600 psi / 800 bar). Having all the required high-pressure valves incorporated, the need for additional high-pressure components is minimized ensuring a cost-effective system. Control of the high-pressure side is achieved by valves on the low-pressure side through the intensifier which adds to safety. The intensifiers are offered with 7 different intensification ratios as standard with additional ratios on request to meet most intensification requirements. The compact design ensures easy installation in new as well as existing hydraulic circuits.

Key Features of the MP-T:

  • All round, in-line pressure intensifier, reciprocating type for continuous flow
  • Most common model in the MP-Series

MP-T Configurations:

  • Rotating Applications (MP-T-R): The MP-T series of hydraulic pressure intensifiers is ideal for making specials, to meet the market demands. The MP-T-R pressure intensifier is based on the MP-T series, but modified to be inserted in a rotating application, where it rotates at 1,500 rpm, while intensifying a supplied pressure of 435 – 3,000 psi (30 – 210 bar).
  • Small Power Pack Applications (MP-T-XP): The MP-T-XP Series hydraulic pressure intensifier is based on the MP-T and is identical to it, except that the MP-T-XP adds a dedicated radial G1/4” port for returning the flow from the high-pressure side to tank. This ensures the oil from the high-pressure side is returned for filtering and cooled before entering the intensifier circuit again. This is used frequently in small power packs and provides for more clean and cool oil flow through the intensifier and the connected tools by allowing the oil to circulate through the tank. 

Technical Data:

  • Inlet Flow: 4 gpm (15 lpm)
  • Supply pressure: up to 2,900 psi (200 bar)
  • End pressure rating: 290 – 11,600 psi (20 – 800 bar). The end pressure is dependent on the ratio and is always proportional with the supplied pressure.
  • 8 intensification ratios
  • High pressure valves integrated
  • Optional built in POV valve
  • Weight: 2.86 lbs (1.3 kg)

Ordering Code Example:

First decide whether the pilot operated check valve, POV, is required, then decide the intensification ratio (i), and finally decide the connections (BSPP or UNF).

Example: MP-T with POV, intensification 5.0 and BSPP connections: MP-T-S-P-5.0-G

Helical Spline Hydraulic Rotary Actuators:

Our rotary actuators are the helical spline design. This means, a piston and a helix, or sliding spline, work together to convert the linear motion of the piston into rotational motion. Composed of two moving parts and some form of housing, the sliding helical splined gear concept within the actuator is used in many applications where a rotary movement is required. Helical Spline Actuators function when the piston is axially displaced using hydraulic pressure causing simultaneous rotation of the piston. Standard amounts of rotation are 90°, 180°, and 360°; but are available generally up to 720° or more. Additional rotation is created by making the spline gears longer while maintaining the same diameter. The primary benefit to this type of product compared to alternative designs such as linkages using hydraulic cylinders (linear actuators) is its compact design.

Hydraulic Rotary Actuators – E3

The Eckart E3 is a hydraulic rotary actuator that has been especially designed for mobile applications; however, it is not limited to such applications. This rotary actuator functions according to the “helical gear” principle and, due to its compact design, only requires a minimum amount of space.

The Eckart E3 is identical in form to the products of its competitors, but has unique selling points which can offer considerable advantages: firstly, there is virtually no backlash; secondly, there is no play in the 4-point roller bearing; and thirdly, no compact seals which can be subjected to stress on both sides are used. Consequently, there is no more wobbling, such as on the work platform, when a lateral movement is made.
