TA-TB COMBINED RETURN-SUCTION FILTER - 2

CLOGGING INDICATOR A visual or electrical indicator is available as an option and allows to monitor the element condition. The port for the indicator is a standard feature. SERIES 30 CLOGGING INDICATOR INTERNAL BYPASS (TA SERIES) RETURN FROM THE SYSTEM The TA-TB filters are designed to work in hydraulic systems combined with hydrostatic transmission, when the return flow is higher than the flow of the boost pump in any operating condition. The oil from the return line of the system is filtered from the inside to the outside of the filter element and goes to the suction of the boost pump...

TA-TB COMBINED RETURN-SUCTION FILTER - 4

INSTALLATION DRAWING TA 23 WITH INTERNAL BYPASS TB 23 WITH EXTERNAL BYPASS WORKING SCHEME Options A and C are recommended for horizontal lter mounting. Options B and D are recommended for vertical lter mounting (drain hole). Options C and D a 125 μm strainer protects the emergency valve in case of brief lack of oil in the suction of the boost pump (situation to be anyway avoided)

FILTER HOUSING PRESSURE DROP Δp (bar) Δp (kPa) CLEAN FILTER ELEMENT PRESSURE DROP N.B. All the curves have been obtained with mineral oil having a kinematic viscosity 30 cSt and specic gravity 0,9 kg/dm3; for uids with different features, please consider the factors described in the rst part of this catalogue. All the curves are obtained from test done at the UFI HYDRAULIC DIVISION Laboratory, according to the specication ISO 3968:2005. In case of discrepancy, please check the contamination level, viscosity and features of the uid in use. BYPASS VALVE PRESSURE DROP FILTER ELEMENT
