5 Safety Instructions for Hydraulic hoses
All instructions as to safe use of hydraulic hoses can be found in the booklet HR 1495 35 219
deliverd with the hoses.
6 Intended use
The hand pump ZPH 3/... serves mainly for operation of LUKAS double-acting cylinders. Jt must
be used only in connection with components out of the LUKAS Rerailing System or the Hydraulik
Tools System 50 MPa, resp. 70 MPa.
An operation of cylinders other than LUKAS is possible, but it must be approved by LUKAS in
each individual case.
Warning
The system operating pressure must not exceed the pressure rating of the lowest rated component
in the system.
Warning
NEVER set the relief valve to a higher pressure than the maximum rated pressure of the pump.
Higher settings may result in equipment damage and/or personal injury.
7 Description
All ZPH/ series hand pumps have the two-stage design, i. e. they are working with two different
speeds:
a high speed in the low-pressure range (LP) for fast extension of a cylinder without load and a low
speed in the high-pressure range (HP) for controlled extension of a cylinder with a load resting on
it.
Switch-over from low to high pressure mode is done automatically by a factory-preset switch-over
valve (see also technical data).
8 Putting into Operation
8.1 Preparing the pump
The pump is to be connected to a hydraulic cylinder by means of suitable hydraulic hose pairs.
Permissible hose pairs (red/blue)
-
5m (ref. 84072/1764)
- 10m (ref. 84072/1765)
The hose pair (with quick couplers) is to be connected directly to the quick couplers on the pump
head: red hose to connection A, blue hose to connection B.
Before pumping: Open the oil filter cap (4) by approx. 1/2 rotation (turn left) and swing away the
clamp (5)
8.2 Connection of hose coupling to cylinder and hand pump
Before coupling, remove the dust protection covers and unlock the connect socket with adjusting
ring by turning it. Withdraw the sleeve and connect plug and socket while holding the sleeve in
this position. Release the sleeve and set the showglass to „red“ with the adjusting ring. Now the
parts are connected and locked. Decoupling is done in the reverse order.
