Pump design
TAP4NN
The TAP4NN gear pump is available in a displacement range from 60.0 to 200.0 cm3/ rev [from 3.66 to
12.2 in3/rev]. Suitable for applications where the pressure is lower than 220 bar[3191 psi] continuous, the
TAP4NN range is released into SAE and European configurations.

Caution
The rated and peak pressure mentioned are for pumps with flanged ports only. When threaded ports are
required a derated performance must be considered. To verify the compliance of an high pressure
application with a threaded ports pump apply to a Danfoss representative.

General Information
Determination of nominal pump sizes
Use these formula to determine the nominal pump size for a specific application:
Vg = Displacement per rev. cm3/rev [in3/rev]
pHD = Outlet pressure bar [psi]
p
= Inlet pressure bar [psi]
ND
Δp = pHD – p
n = Speed min-1 (rpm)
ηv = Volumetric efficiency
ηm = Mechanical (torque) efficiency
ηt = Overall efficiency (ηv • ηm)
ND
