Performance

Housing pressure drop

Using fluid with s.g. 0.9 housing pressure drop is directly proportional with to specific gravity.

Bypass valve curves

Bypass valve pressure drop using fluid with s.g. 0.9. Valve pressure drop is directly proportional to fluid specific gravity.



Filter assembly clean pressure drop

=ΔP housing +ΔP element

Element pressure drop factor

Multiply flow rate byΔP factor/1000 to determine pressure drop (bar) with fluid at 30 cSt 0.9 S.G. Correct for other viscosities and specific gravity multiplying new viscosity in cSt/30 x new S.G./0.9.

Sample ΔP calculation

HH9680C20KNTBM at 200 L/min flow rate using a hydraulic fluid at 50 cSt and specific gravity (s.g.) 1.2.

ΔP assembly
= ΔP housing + ΔP element
= (0.3 x 1.2/0.9)
+ ((200 x 1.41/1000) x 50/30 x 1.2/0.9)
= 0.4 (housing) + 0.63 (element)
