1 Low-wear stainless steel piston
2 Improved suction performance and low pressure
losses by optimised stream cross sections.
3 Guide bar with large diameter and reduced friction
and wear characteristics by special suface treat-
ment.
4 Aluminium crankcase with special geometry for
optimised rigidness and reduction of the oil tem-
perature in the crank drive
5 Ventilation screw allows easy filling of oil and pre-
vents pressure accumulation and therefore leaks
in the oil room
6 Highly durable, forged crankshaft
7 Connection rod made of highly durable special
bronze with very good emergency run features
8 Large oil volume allows optimal lubrication of the
bearing and warrants large maintenance intervals.
9 High serviceability by robust, split bearing and re-
movable bearing covers
10 Oil filling nozzle
11 Maintenance-free, low wear high-pressure seal
set, hot water suitable up to 85°C, consisting of
high and low pressure seal.
12 The design of the valve screws makes for a relia-
ble seal and reduces the risk of excessive torque
values.
13 Pressure loss optimised stainless steel valves with
high hydraulic effect
14 High-strength, forged cylinder head made of cor-
rosion-resistant special alloy
ECO-brass
ECO-brass (lead free, food grade) is a special brass
alloy. Cylinder heads made of ECO-brass have a
high resistance against various aggressive media.
Side oil sight glass to monitor the oil level (not pic-
tured)
Note:
For thermal reasons the appliance should not
be operated with full covering (lid and rear cover).
