Buy VDR-11A VDR-11B VDR-11A/11B-1A2/1A3 Vane Pump | Partsdic®

Vane pumps are positive displacement pumps that consist of a circular rotor with radial slots and vanes that slide in and out of these slots.

As the rotor rotates, the vanes create chambers between the rotor and the pump housing, which draw in and transport fluid. Let's delve into the specific features and specifications of the VDR-11A, VDR-11B, and VDR-11A/11B-1A2/1A3 vane pumps:

VDR-11A: The VDR-11A is a single-stage vane pump with a compact design suitable for medium-duty applications. It offers a maximum displacement of 11 cm³/rev and can handle pressures up to 175 bar (2,540 psi). The pump's operating temperature ranges from -20°C to 80°C (-4°F to 176°F), making it suitable for a wide range of environments. The VDR-11A incorporates high-quality materials to ensure durability and long service life.

VDR-11B: Similar to the VDR-11A, the VDR-11B is a single-stage vane pump designed for medium-duty applications. It shares many features with the VDR-11A, including the maximum displacement of 11 cm³/rev and the operating temperature range of -20°C to 80°C (-4°F to 176°F). However, the VDR-11B offers enhanced performance with a maximum pressure rating of 210 bar (3,045 psi), making it suitable for applications requiring higher pressures.

VDR-11A/11B-1A2/1A3: The VDR-11A/11B-1A2/1A3 is a two-stage vane pump that combines the features of both the VDR-11A and VDR-11B, providing a broader range of capabilities.

It offers a maximum displacement of 11 cm³/rev and can handle pressures up to 210 bar (3,045 psi). The pump is designed to operate in temperatures ranging from -20°C to 80°C (-4°F to 176°F). The two-stage configuration enables improved efficiency and higher pressure outputs, making it suitable for demanding applications.

All these vane pumps feature a robust construction with high-quality materials such as cast iron or aluminum alloy for the pump housing, ensuring excellent durability and resistance to wear. The vanes are typically made from carbon composite or other suitable materials to provide smooth operation and reduce friction.

These vane pumps are self-priming, meaning they can evacuate air from the system and create a vacuum, allowing efficient fluid transfer even in situations with limited fluid availability. They exhibit low noise levels during operation and have relatively low pulsation characteristics, contributing to smoother system performance.
