Low Noise Technology
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 availabel for Concentric gear pumps group 1 and 2 and 2.5 (group 3 on demand)..
-
Multiple Sections
Multiple Sections – PumpsTo meet specific customer needs, Concentric can design multiple section gear pumps Group 1 on demand (up to 2 sections).These pumps are ideally suited to supply flow to multiple hydraulic functions from one power source..Customer Value:Compact designCosts saving compared to separate pumps with associated fittings and hoses..
-
Valve Integration
Valve Integration – W-Series and F12-SeriesConcentric offers a wide range of integrated valve solutions for gear pumps and motors..
Examples:Anti-cavitation check valves(Proportional) pressure relief valvesValve manifolds for multiple functions.
Also speed sensors can be integrated.
