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.

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

Length Code	AZ	AP	AN	AS	AT

Sample ΔP calculation

UR329 Series 20" length housing with F48 (3" SAE) split flange ports using AN grade media. Operating conditions 200 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
= (0.2 x 1.2/0.9) bard (housing)
+ ((200 x 0.72/1000) x 50/32 x 1.2/0.9) bard (element)
= 0.26 bard (housing) + 0.3 bard (element)
= 0.56 bard (8.1 psid)
