P & R Hydraulics is a sales distributor for Turolla (a member of the Danfoss Group), which means we buy direct from them and can supply the items to you at very competitive prices.  We hold a wide range of Turolla products in stock because we understand the need to keep your equipment running for maximum productivity.  One such product is the Group 3 series of aluminium gear pumps, of which we have a variety of models on our shelves.

The Turolla Group 3 series is a range of peak performance fixed-displacement gear pumps.  Constructed of a high strength extruded aluminium body with aluminium cover and flange.  All pumps are pressure balanced for exceptional efficiency.

Features and benefits of Group 3 gear pumps


• Wide range of displacements from 22 to 90 cm3/rev [from 1.34 to 5.49 in3/rev]
• Continuous pressure rating up to 250 bar [3625 psi]
• Speeds up to 3000 min-1 (rpm)
• SAE, DIN and European standard mounting flanges
• High quality case hardened steel gears
• Multiple pump configurations in combination with SNP1NN, SNP2NN and SNP3NN

Pump design


SEP3NN

The SEP3NN gear pump is available in a limited displacement range from 22.0 to 44.1 cm3/rev (from 1.34 to 2.69 in3/rev).  They are suitable for applications where the pressure is lower than 210 bar (3045 psi).  The SEP3NN range is released into SAE and European configurations.  The overall length is reduced by 12mm (0.47 in) in respect of the SNP3NN.

SNP3NN

The SNP3NN is available in the full displacement range from 22.0 to 88.2 cm3/rev (from 1.34 to 5.38 in3/rev), and with higher pressure ratings than the SEP3NN.  This is due to the pressure balance on each side of the gears obtained with pressure-balance plates made in antifriction alloy that contribute to high volumetric efficiency and maximum sealing as well.
