∆P housing ∆P element Pressure

RF60 ∆P housing for fluids with sp gr = 0.86: ∆P element = flow x element ∆P factor x viscosity factor Drop KF30
Information
El. ∆P factors @ 150 SUS (32 cSt): Based on
8R3 .35 Flow Rate TF50
8R10 .30 and Viscosity

If working in units of bars & L/min, divide above
factor by 54.9. NOF30-05
Viscosity factor: Divide viscosity by 150 SUS (32 cSt).
sp gr = specific gravity
NOF50-760
Sizing of elements should be based on element flow information provided in the Element Selection chart above.

Notes ∆P filter = ∆P housing + ∆P element
Exercise: NMF30
Determine ∆P at 15 gpm (57 L/min) for
RF608R10SD5 using 200 SUS (44 cSt) fluid.
RMF60
Solution:
∆P housing = 5.0 psi [.35 bar] Cartridge
∆P element = 15 x .30 x (200÷150) = 6.0 psi Elements
or
= [57 x (.30÷54.9) x (44÷32) = .41 bar]
∆P total = 5.0 + 6.0 = 11.0 psi HS60
or
= [.38 + .41 = .79 bar] MHS60
