COMPATIBILITY (ISO 2943:1999)
Full with fluids: HH-HL-HM-HV-HTG (according to ISO
6743/4). For fluids different than the above mentioned,
please contact our Sales Department.
All tests performed according
to the following standards:
ISO 2941: Element collapse resistance test
ISO 2942: Production integrity test
ISO 2943: Fluids compatibility
ISO 3723: End load test method
ISO 3724: Flow fatigue resistance method
ISO 3968: Pressure drop versus flow rate
ISO 16889: Multipass test.
For further information contact our Technical Dept.
The KTS 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 with a 50 kPa (0,5 bar)
pressurization. The exceeding flow rate goes into the
reservoir.
A flow rate 50% higher that the flow required by the boost
pump is recommended in normal operating conditions.
Two versions are available:
- with internal bypass system.
- with external bypass valve
ADVANTAGES
- One filter for two functions: filtering the oil returning
from the hydraulic system and feeding the boost pump
with cleanest oil
Anti-Cavitation
Valve
125µm
Protection Strainer
- Pressurization allows absolute filtration on the suction
of the boost pump
- No cavitation risk

Pressurization Valve
- Filter element working from inside to outside allows
retained contamination to be completely removed
when replacing the element
