ScanWill is a supplier and pressure intensifier manufacturer for various applications including construction, mechanical, marine, and industrial.
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-Linear Actuator Standard Features:

Like all Eckart hydraulic rotary actuators, the SM4 is designed with helical spline technology. The actuator operates with a piston and a helical or sliding spline mechanism, which work in tandem to transform the piston’s linear motion into rotational movement.
High torque in a compact profile
Helical spline actuators deliver impressive torque within a compact construction, making them ideal for applications where space is limited.
Less risk of contamination and physical damage
Protective housing keeps all moving parts safe from debris and moisture, ensuring consistent operation in demanding environments, especially for mining applications.
Low maintenance and wear-resistant moving parts
All internal components are fully immersed in oil ensuring preventative wear.
Extended-period nitriding ensures a long service life of the rotary actuator.
Helical spline rotary actuators offer safer alternatives to linkages for the operator, since there are no exposed parts.
Standard Rotations:
Standard rotations are 90°, 180°, 270°,and 360°. Other rotations can be supplied on request by using the model with the next standard rotation up and limiting the stroke of the piston in accordance. Also available are special models with rotations in excess of 360°. 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.

The Eckart HSE4 rotary-linear actuator is a combination of a rotary actuator and a dual-action linear cylinder, allowing for full flexibility in a minimal amount of space. Consequently, both a rotary movement and a linear movement can be executed even when operated in an extremely small area. Additionally, since the rotary actuator and the linear cylinder are hydraulically-driven separately, any movement sequences can be selected: for example, rotating to the left and right, extending linearly, and retracting.
Furthermore, if both components are driven evenly, then both types of movement will be executed synchronously. The directional valve controls the movement of rod rotation and linear stroking. Because of its torque, angle of rotation, pressure range, positioning accuracy, stability of position, type of attachment, and its dimensions, the Eckart HSE4 rotary actuator can be used in a wide range of applications.
Common applications for the HSE4 include lifting and turning. Not only is the HSE4 a compact and robust unit, but it is also wear-resistant, efficient, and cushioning. Additionally, the HSE4 unit can be driven via “black and white” or with proportional, control, and servo valves. For the purpose of subsequent driving, the piston end-positions at the linear cylinder and at the rotary actuator can be scanned via electronic end-position acknowledgement mechanisms. Ultimately, with the HSE4, you have a high-performing product that is both robust and compact, allowing for optimal adaptation depending on your specific requirements.
