Parker 3349111292 Hydraulic Gear Pump

Parker P/N: 3349111292 Hydraulic Gear Pump (PGP511 Series) – New

The Parker Hannifin 3349111292 is a high-pressure, fixed-displacement external hydraulic gear pump built on Parker’s heavy-duty PGP511 aluminum-body architecture (complete model code: PGP511A0140CS2D3NL2L1B1B1). Engineered for severe-duty marine, industrial, and mobile fluid power circuits, this pump delivers 14.0 cm³/rev (0.85 in³/rev) displacement, sustaining continuous working pressures up to 250 bar (3,625 psi) and peak intermittent pressures up to 275 bar (3,988 psi).

The 3349111292 minimizes internal hydrodynamic blow-by and oil slip while achieving volumetric efficiencies exceeding 93% across varied thermal operational bands. This unit is suited for demanding marine auxiliary power units (APUs), electro-hydraulic steering trims, deck capstans, bow-thruster controls, and industrial power packs requiring long-duty cycles and low structural noise.

Model Details

• Manufacturer: Parker Hannifin
• Manufacturer Part Number (MPN / Ordering Code): 3349111292
• Full Engineering Model Code: PGP511A0140CS2D3NL2L1B1B1
• Product Series: PGP511 (Group 2 Series)

Features

1. Continuous 250 Bar Capability: Rugged 12-tooth drive/driven gear profiles optimize tooth engagement, lowering operational pulsation while maintaining reliable 250 bar continuous operating pressure.
2. Hydrostatic Thrust Plate Balancing: Self-compensating axial thrust plates eliminate thermal seizure risks and curb high-pressure bypass leakage across the entire operating viscosity profile.
3. High Volumetric Efficiency (>93%): Precision-ground journal bearings and low clearance tolerances provide optimal flow repeatability at drive speeds up to 3,500 RPM.
4. Standard European 4-Bolt Mounting Flange: Features a standard 36.5 mm pilot/centering register with a 71.4 mm x 96 mm bolt circle, paired with a heavy-duty 1:8 conical taper drive shaft.
5. Low Noise Footprint for Enclosed Engine Rooms: Optimized gear-root relief chambers alleviate trapped fluid shock load, reducing sound emission in closed marine machinery spaces.

Frequently Asked Questions

How do I verify the rotation direction of the Parker 3349111292 before install?

The 3349111292 is configured for Clockwise (Right-Hand / CW) rotation. Looking directly face-on at the drive shaft end, the inlet (larger port, Code L2) is positioned on the left, and the high-pressure outlet (smaller port, Code L1) is situated on the right. Never run this unit in reverse; driving a clockwise gear pump counter-clockwise will rupture internal balancing thrust seals within seconds.

Can this pump run on fire-resistant or bio-degradable hydraulic oils (EAL)?

Standard units ship with Nitrile (NBR) shaft and body seals suitable for mineral oils (DIN 51524 types HLP, HLVP). If operating with synthetic esters (HEES) or phosphate ester fluids (HFDR) commonly required for offshore environmental regulations (Vessel General Permit – VGP), specify FKM (Viton) seals prior to commissioning to avoid compound swelling.

What is the difference between Parker PGP511 and legacy Commercial Intertech gear pumps?

The PGP511 series is Parker’s refined generation of the proven Commercial Intertech Group 2 pump architecture. It features tighter internal running clearances, optimized low-noise gear teeth profiles, and higher continuous pressure ratings (250 bar vs. 200 bar on older cast units), while maintaining interchangeable European mounting and port dimensions.

What is the recommended filtration rating for the 3349111292 hydraulic pump?

To ensure the target lifespan of >10,000 operational hours, install a return-line filter maintaining ISO 4406 Cleanliness Level 19/17/14 or better, paired with a filter element rating of β10≥200. Do not use fine suction strainers below 125 microns, as high-viscosity cold fluid may cause pump cavitation.
