Pump and Motor:
Synesso™ uses a Fluid-o-tec rotary
vane pump which boosts incoming water
pressure to 9 bar when the motor is acti-
vated. Pressure can be adjusted by loosen-
ing the nut on the right side fitting and then
turning the adjustment screw clockwise
(increasing pressure) or counter-clockwise
(decreasing pressure).
Pump configurations:
Until serial number 356, Synesso™ ma-
chines had a single inlet configuration as
the standard. After 356, the dual inlet con-
figuration is the standard. Hydras have a
separate pump and motor per group, there-
fore all Hydras come equipped with single
inlet style pumps.
Water Inlet control valves:
Serial numbers 1-340 feature the Skinner-style
valves shown in the upper part of the picture on
the left. These were replaced on serial number
341 onwards with the Parker ZB09 for ease of
repair or replacement.
Both valve styles feature electronic coils which,
when energized, move a piston which allows
water flow through the valve. When deactivated,
the piston’s presence in the valve stops the flow
of water.
The picture on the next page shows the steam
tank autofill configuration. All 3 of the water con-
trol valves are now Parker ZB09. Upgrade kits
are available through Synesso™.
