Group 4 gear pumps attributess
•Wide range of displacements from 60 to 200 cm3/rev [from 3.66 to 12.2 in3/rev]
•Continuous pressure rating up to 220 bar [3191 psi]
•Speeds up to 3000 min-1 (rpm)
•SAE and European standard mounting flanges
•High quality case hardened steel gears
•Multiple pump configurations in combination with SNP1NN, SNP2NN and SNP3NN

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.
