The Danfoss Industrial Square Vane Pumps V10, V20, V20H, V2010, and V2020 are a series of pressure-balanced vane pumps suitable for a variety of low- and medium-pressure mobile and industrial applications. Here's an overview:
Design Features
Pressure-Balanced Design: The 12-vane pressure-balanced design reduces flow pulsation and noise, extending pump life and improving maintainability.
Modular Design: Single and dual pump options are available with a variety of displacements to meet the needs of various applications.
Performance Specifications
Displacement: The V10, V20, and V20H offer displacements ranging from 3 to 42cc (0.2 to 2.6 cubic inches).
Pressure: The V10 and V20 have continuous pressure ratings up to 172 bar (2500 psi), while the V20H has a continuous pressure rating up to 205 bar (3000 psi).
Flow Rates: The V2010 dual pump offers flow rates of up to 49 l/min (13 us gal/min) for the shaft-end pump and 26 l/min (7 us gal/min) for the cover-end pump; the V2020 dual pump offers flow rates of up to 49 l/min (13 us gal/min) for the shaft-end pump and 42 l/min (11 us gal/min) for the cover-end pump.
Model Features
The V10 and V20 are single, fixed-displacement pumps with hydraulically balanced rotors. They are suitable for small industrial or mobile machines and can also serve as pilot or auxiliary pumps in complex systems.
The V20H is a high-pressure version of the V20. While maintaining the same dimensions, it delivers higher pressures, up to 205 bar (3000 psi), making it suitable for applications requiring higher pressures.
The V2010 and V2020 are dual pumps that can power two independent hydraulic circuits from a single power source, or combine the two components to provide higher flow rates. They feature a compact design and simple installation.
Applications
They can be used as main system pumps in small industrial and mobile equipment, or as pilot and auxiliary pumps in complex systems.
They are commonly used in standard steering pump technology for heavy-duty trucks and interstate buses, as well as in power steering, fan drives, street sweepers, forklifts, and other applications.

What are the primary applications for Danfoss V10 and V20 series pumps?
They are commonly used as primary or auxiliary pumps in small industrial machinery, heavy-duty trucks, steering systems for interstate buses, power steering configurations, fan drives, street sweepers, and forklifts.
How does the pressure-balanced design benefit the pump system?
The 12-vane pressure-balanced configuration drastically minimizes flow pulsation and noise. This extends the service life of internal components and greatly simplifies pump maintenance.
What is the difference between the standard V20 and the V20H model?
The V20H is a high-pressure variant of the standard V20. While maintaining the identical physical dimensions, it can achieve a higher continuous pressure rating of up to 205 bar (3000 psi) compared to the 172 bar (2500 psi) limit of the standard V20.
What flow rates can be expected from the V2010 and V2020 double pumps?
For the V2010, the shaft-end delivers up to 49 l/min and the cover-end provides up to 26 l/min. For the V2020, the shaft-end delivers up to 49 l/min and the cover-end provides up to 42 l/min.
What type of mounting and shaft styles are available for these vane pumps?
They utilize a standard SAE-A 2-bolt mounting format and offer versatile shaft variations including splined 11-tooth configurations and 3/4" straight keyed options.
