DYNAVIS®-formulated hydraulic fluids
DYNAVIS® is a technology for formulating hydraulic fluids which optimizes their viscosity. Fluids with constant viscosity ensure greater efficiency and less energy consumption – whether in construction equipment like excavators, wheel loaders, skid steer loaders and backhoes - in mining equipment like screening plants and dump trucks or - in industrial equipment like injection molding machines, robotics and all other types of stationary equipment using hydraulics.
Simply changing the hydraulic fluid to one formulated with DYNAVIS® technology allows nearly any hydraulically powered machine to operate more efficiently, dynamically, and accurately.
The use of hydraulic fluids formulated with DYNAVIS® technology pays for itself in just a short time, most notably in extremely demanding applications, while also ensuring higher returns with lower energy consumption and reduced emissions.
Demands for Hydraulic Fluids
So the viscosity has to be high enough to protect the equipment and to guarantee pump efficiency.
On its way from the tank to the pump, the fluid has to pass several bottlenecks like valves. Friction within the fluid itself and friction on the walls creates heat. Compression in the pump creates more heat. The heat reduces the viscosity.
Ideally the viscosity in the pump doesn't get too low to maintain power. For this reason, a fluid with a higher viscosity is normally used because it heats up and becomes thinner on its way to the pump, thus requiring more power for transportation.
Hydraulic fluids following the DYNAVIS® performance standard keep their viscosity over a broad temperature range. So they save energy, enhance performance and protect the equipment. So the viscosity has to be high enough to protect the equipment and to guarantee pump efficiency.
