ABER – B33D,34D – Oil Hydraulic Tandem Gear Pump
Maximize your mobile machinery's hydraulic performance and streamline your drivetrain with the ABER B33D and B34D Series Tandem Gear Pumps. Available now at Thm Hydraulics, these highly advanced, dual-flow oil hydraulic pumps are engineered to power two independent fluid circuits simultaneously from a single power source. Covering an extensive range of high-capacity sizes from 38 up to 125, the B33D/34D Series operates efficiently within a broad rotational speed range of 500 RPM up to a blistering 2600 RPM. Designed for incredibly fast, direct assembly into standard Power Take-Off (PTO) units, this tandem series entirely eliminates the need for complex, heavy mounting brackets. Featuring bidirectional versatility, exceptionally low noise generation, and a remarkably lightweight footprint, the ABER Tandem Gear Pump is the ultimate solution for complex, multi-function commercial vehicles.

Key Features & Engineering Advantages
- Tandem Dual-Flow Efficiency: The double-gear architecture allows operators to drive two completely separate hydraulic functions—such as a heavy lifting cylinder and an auxiliary rotary motor—simultaneously from just one PTO slot, saving critical chassis space.
- Broad RPM Operating Range: Engineered to deliver consistent, reliable fluid power at low idle speeds (500 RPM) while safely sustaining continuous operation at high-velocity engine speeds up to 2600 RPM.
- Rapid Direct PTO Mounting: Designed to bolt directly into your commercial vehicle's PTO unit. This fast-to-mount architecture bypasses the need for vulnerable external drive shafts and drastically reduces installation labor.
- Versatile Bidirectional Operation: Available in fully bidirectional models or unidirectional versions featuring a safe, changeable direction of rotation, ensuring the pump adapts seamlessly to diverse drivetrain configurations without risking internal mechanical damage.
- Ultra-Compact & Acoustic Superiority: Despite housing two pumping sections, the tandem design remains remarkably light and small. Precision-meshed internal gears minimize fluid pulsation, ensuring low-noise operation for strict urban compliance.
Ideal Industry Applications:-
The tandem flow and direct PTO mounting of the ABER B33D/34D Series make it the mandatory hydraulic solution for:
- Multi-Function Commercial Trucks: Powering the primary and secondary hydraulic circuits on heavy roll-off refuse carriers, multi-deck car transporters, and heavy-duty recovery wreckers.
- Mobile Cranes & Lifting: Providing the simultaneous, dual-flow precision needed to safely operate the boom extension and winch circuits on truck-mounted knuckle boom cranes.
- Forestry & Agricultural Equipment: Driving demanding, independent auxiliary implements on heavy timber loaders, delimbers, and high-horsepower tractors.
- Municipal & Utility Fleets: Supplying reliable, dual-circuit power to heavy-duty plow hydraulics and salt-spreader augers simultaneously.
Why Choose the ABER B33D & B34D Series?
- Two Pumps in One Footprint: Save money, chassis space, and drivetrain complexity by powering two independent fluid circuits from a single, compact unit.
- Uncompromising Speed Range: Operates flawlessly across a massive 500 to 2600 RPM band, ensuring your hydraulics work effectively whether you are idling or running at full throttle.
- Accelerated Installation: Mounts directly to the PTO fast, allowing your maintenance team to get heavy vehicles back onto the job site earning revenue.
