Low Noise Technology (Calma-Series)
Low Noise Technology – Calma-Series (Dual Flank Engagement)
Concentric has developed the Low Noise Calma-Series for gear pumps, based on the patented Dual Flank Engagement. The Calma-Series provides a reduced pressure pulsation by 75% vs. traditional gear pump designs, resulting in a low noise operation.
.
Calma-Series gear pumps are well suited to applications on electrical forklift trucks and other mobile equipments, where low noise and high efficiency are required.
.
The Calma-Series is available for Concentric gear pumps Group 1 and 2 and 2.5 (Group 3 on demand)..
-
Multiple Sections
Multiple Sections – Pumps
To meet specific customer needs, Concentric can design multiple section gear pumps, also in combination of different pump groups (e.g. Group 2.5 + Group 2).
These pumps are ideally suited to supply flow to multiple hydraulic functions from one power source.
.
Customer Value:
Compact design
Costs saving compared to separate pumps with associated fittings and hoses.
.
Multiple gear pump combinations are available with up to four sections with a wide interface range.
-
Valve Integration
Valve Integration – W-Series and F12-Series
Concentric offers a wide range of integrated valve solutions for gear pumps and motors.
.
Examples:
Anti-cavitation check valves
(Proportional) pressure relief valves
Valve manifolds for multiple functions
.
Also speed sensors can be integrated.
-
Reinforced Front Bearing
Reinforced Front Bearing – F12-Series
Concentric offers reinforced front bearings (with SAE-B interface) for extended radial and axial drive shaft load capabilities.
.
Max. radial load: 4700 N
Max. axial load: 1300 N
.
Examples:
Fan drives
Belt drives
