Pressure Drop Information

Housing pressure drop using fluid with 0.9 S.G.

Housing pressure drop is directly proportional to specific gravity.

HCG300 Filter Elements – bard/1000 L/min (psid/US gpm)

Length Code	KN	KS	KD	KT
04	5.35 (0.29)	3.48 (0.19)	2.68 (0.15)	2.43 (0.13)

Multiply actual flow rate times factor in table above 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.

Sample ΔP calculation

G310 Series 4 in. length housing with C16 ports using KN grade media. Operating conditions 100 L/min flow rate using a hydraulic fluid at 45 cSt and specific gravity (s.g.) 1.2.

Total Filter ΔP
= ΔP housing + ΔP element
= (0.32 x 1.2/0.9) bard (housing)
   + ((100 x 5.35/1000) x 45/32 x 1.2/0.9) bard (element)
= 0.427 bard (housing) + 1.0 bard (element)
= 1.43 bard (20.70 psid)
