The VDR-1B and VDR-11B pumps are designed to handle high-pressure hydraulic systems commonly found in oil drilling rigs, hydraulic power units, and other oilfield equipment.
These pumps are driven by electric motors or internal combustion engines, depending on the specific application requirements.
The VDR-1B pump is a single-stage, variable displacement axial piston pump. It is capable of delivering a maximum flow rate of 150 liters per minute (lpm) and operates at a maximum pressure of 280 bar. The displacement range of this pump is adjustable between 20 cc/rev and 45 cc/rev, allowing for precise control over the hydraulic system's flow rate. The VDR-1B pump is equipped with a pressure compensator to maintain a constant pressure regardless of the load conditions.
On the other hand, the VDR-11B pump is a two-stage, variable displacement axial piston pump. It offers a higher maximum flow rate of 270 lpm and can operate at a maximum pressure of 320 bar. The displacement range of the VDR-11B pump is adjustable between 35 cc/rev and 77 cc/rev. This pump also features a pressure compensator to ensure consistent pressure during varying load conditions.
Both pumps feature a rugged construction using high-quality materials such as cast iron and steel, making them highly durable and capable of withstanding harsh operating environments.
They are also designed for easy maintenance and serviceability, with readily accessible components and a straightforward disassembly process.
To ensure efficient and reliable performance, the VDR-1B and VDR-11B pumps incorporate advanced hydraulic technologies. These include precision-machined components, low-friction seals, and optimized internal clearances to minimize energy losses and improve overall efficiency. The pumps are also equipped with robust filtration systems to prevent contaminants from entering the hydraulic system, thereby enhancing its reliability and longevity.
The VDR-1B and VDR-11B pumps can be customized with various control options to meet specific application requirements. These options include manual control, proportional control, or electro-hydraulic control, allowing for precise regulation of the hydraulic flow and pressure. The pumps can also be integrated into complex hydraulic systems using various accessories such as pressure sensors, temperature sensors, and flow control valves.
