The MP-Series of hydraulic pressure intensifi ers are
reciprocating, and will automatically increase a supplied pressure to a higher end pressure. Fig. 1 shows
the basic principle of the intensifi ers, consisting of a
piston arrangement and a Piston Control Valve, PCV.
The position of the pistons will at the end of every stroke
prompt a signal S to the PCV, which makes this change
position, ensuring the pistons are moving in the opposite
direction. This cycle will continue until the end pressure
has been reached. At this point the pistons stop, and will
now only move to maintain the end pressure.
Function:
Fig. 1:
When a hydraulic fl uid is supplied to the P-connection of
the intensifi er and the T-connection is connected to tank,
the oil will be directed through the check valves CV1 and
CV2 to the high pressure connection HP. If the internal
pilot operated check valve POV is incorporated the oil will
go straight to the HP connection. In this situation all the
fl ow supplied goes to the high pres su re side ensuring a
fast fi lling of the system. When pump pressure has been
reached, the intensifi er pistons will deliver the fl ow to the
high pressure side, and continue to do so until the required
end pressure has been reached. The pistons then stop,
and will only move to make up for a pressure loss due to
leakage or consumption.
A general fl ow curve showing how the intensifi er works is
shown in Fig.2. For evacuating the high pressure side the
internal POV is used. This valve is opened by directing the
supplied pressure to the T-port and connecting the P-port
to tank. This allows the oil from the high pressure side to
fl ow directly back to tank.

The MP-T is an in-line pressure intensifi er designed to be positioned in a
low pressure hydraulic system, and will provide higher pressure exactly
where needed (max. 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 intensifi er which adds to safety.
The intensifi ers are offered with 7 different intensifi cation ratios as standard
with additional ratios on request to meet most intensifi cation requirements. The
compact design ensures easy installation in new as well as existing hydraulic
circuits.
Flow & Pressure:
The supplied fl ow and pressure to the MP-T are dependant on the intensifi cation ratio chosen. The table shows the fl ow
and pressure for each model. Flow Q1 is when the pump pressure has been reached, and fl ow Q2 is moving up the vertical part of the curve (see graph on page 2). Please note fl ow values will vary with the viscosity of the fl uid. Inlet values
must not be exceeded.
Ordering Code:
First decide whether the pilot operated check valve,
POV, is required, then decide the intensifi cation ratio
(i), and fi nally decide the connections (BSP or UNF).

Example:
MP-T with POV, intensifi cation 5.0 and
BSP connections: MP-T-P-5.0-G
Dimensions in mm
The standard MP-T will provide pressure intensifi cation as required. As an
option a built in pilot operated check
valve, POV, allows the high pressure
side to be relieved through the intensifi er (see page 3).
