China Wholesale LFZ Medium Pressure Filters Series /Hydraulic Line Filter

China Wholesale LFZ Medium Pressure Filters Series /Hydraulic Line Filter

1.LFZ series filters are installed on the medium pressure line, with these characteristics of high filtration accuracy, small flow rate resistance,low initial pressure loss, high dirt-holding capacity, which can meet the various requirements from the customers (can replace Hydac LF series).

2.Filter basic construction
LFZ series filter consists of the cover and the spin-on housing . 
2.1 Housing material
Filter cover: High strength casting aluminum alloy
Filter bowl: High strength aluminum alloy 
2.2 Seals
Perbunan (=NBR) (-30~+120°C);  Viton=FPM (-20~+200°C)
2.3 Filter element
Filter medium material
High strength carbon steel skeleton
2.4 Optional accessories
Without clogging indicator,with steel plug
Visual clogging indicator:CM-03
Electrical clogging indicator:CM-05
Combined visual /electrical clogging indicator:CM-08
Bypass valve(setting 6 bar)
2.5 Type of connection (chosen according to the filter type)
Inch threaded connection

5.The total filter assembly pressure drop is the sum of housing and element pressure drop,filter selection calculated as per the following curves.
5.1 Housing pressure drop / flow rate characteristic curves
Housing pressure drop /flow rate characteristic curves are according to ISO3968, and suitable for the mineral oil with density 0.86  kg/dm³ and kinematic viscosity 30 mm²/s. 

5.2 Differential pressure / flow characteristic curves of filter element
The characteristic curves of filter element are suitable for the mineral oil with kinematic viscosity 30mm²/s. . Differential pressure and viscosity is proportional.

DFFILTRI was founded in 1995, since then we devoted ourselves to research, develop and produce many kinds of hydraulic filters, air filters, hydraulic system accessories, cleaning and filtration equipments, pump valve components. DFFILTRI is our brand, which enjoys high popularity and it has successfully achieved the position both in China and across the world.
DFFILTER filtration technology testing center covers a total area of 450 square meters, of which, clean room area of 200 square meters, and cleanliness is up to 100,000 levels. The centre undertakes filtration technology inspection and testing for in-house science research, production and industry service.   
On-line particle counter of BETAB-HIAC/POYCO type (8000A/8000S) provided by HIAC/POYCO company in USA, and its supporting machine"Multi-pass test" and "single-pass test" implements ISO16889 new standard and other international standards perfectly.
Testing center also has the developed equiment for filter performance testing, which can make the comprehensive examination for filter element/cartridge performance. These can insure that company's filter with high capacity, long life, high reliable in full compliance with our customer's  requirement.
The testing centre can take 7 tests of hydraulic filter performance evaluation, they are as follows:
ISO 2941 Verification of collapse/burst resistance
ISO 2942 Verification of fabrication integrity and determination of the first bubble point
ISO 2943 Verification of material compatibility with fluids
ISO 3723 Method for end load testing
ISO 3724 Verification of flow fatigue characteristics
ISO 3968 Evaluation of pressure drop versus flow characteristics
ISO 16889 Multi-Pass method for evaluating filtration performance
