Performance

Pressure Drop Information

Housing pressure drop using fluid with 0.9 S.G.

Housing pressure drop is directly proportional to specific gravity.


Element Pressure Drop

Multiply actual flow rate times factor in table below to determine pressure drop with fluid at 32 cSt (150 SUS), 0.9 S.G. Correct for other fluids by multiplying new viscosity in cSt/32 (SUS/150) x new S.G./0.9. Note: factors are per 1000 L/min and per 1 US gpm.

299 Series Filter Elements — bard/1000 L/min (psid/US gpm)

Sample ΔP calculation

UT279 Series 8" length housing with C16 (1" BSP) threaded ports using AN grade media. Operating conditions 50 L/min flow rate using a hydraulic fluid of 50 cSt and specific gravity (s.g.) 1.2.

Total Filter ΔP
= ΔP housing + ΔP element
= (0.04 x 1.2/0.9) bard (housing)
+ ((50 x 2.83/1000) x 50/32 x 1.2/0.9) bard (element)
= 0.05 bard (housing) + 0.29 bard (element)
= 0.34 bard (4.9 psid)
