Return line Filters Series UCMF
Description
UCMF series filters are suitable for applications on the return line of hydraulic circuits, installed semi-immersed in the oil tank.They are available with connection ports from 1/2" up to 2" and flow rate from 30 up to 400 l/min.The filters series UCMF are supplied as standard with By-pass valve in the cartridge.
Technical data complete filter
l Filter head and cap in aluminium alloyl Bowl in fiber glass reinforced Nylon or steell Max working pressure = 3 barl Max test pressure = 6 barl Burst pressure = 10 barl Differential collapse pressure filter elements = 3 barl By-pass valve set at 1,7 bar ± 10%l Working temperature -25°C up to +95°Cl Connections: BSP - NPT - SAE threaded ports from 1/2" up to 2"
Technical data filter elements
l A/B: paper treated with resin, filtration rating 10 and 25 microns βx ≥ 2l F/N/G/H: inorganic fibres, filtration rating 3, 6, 10 and 25 microns βx ≥ 200l L: stainless steel square wire mesh (AISI 304), filtration rating 60 micronsl C/E: brash square wire mesh, filtration rating 90 and 125 micronsl End cap in Polyamidel Support tube in galvanized steell Support mesh in galvanized steel with epoxy coating

By-pass valve pressure drop
By-pass valve pressure drop
All the curves have been obtained with mineral oil with a
density of 860 Kg/m 3. The pressure drop is proportional to the
variation of density.
Pressure drop (in accordance with ISO 3968)
The assembly pressure drop is obtained by adding the
pressure drop of the filter housing with the pressure drop of
the filter element.
