New problems, new solutions

Hydraulic fluid producers introduce additives (usually several, as an additive package) into base oils to give them the characteristics they need for the demanding conditions of hydraulic systems. Additives improve viscosity, reduce friction, prevent wear, and allow the fluid to tolerate high temperatures without oxidizing. Group I base oils contain aromatics, most of which are toxic, and zinc, a heavy metal that promotes wear resistance. Because of their toxicity and potential threat to environmental systems, they no longer comply with current international environmental standards....More

Hydraulic filter puts a new spin on contamination control

Keeping hydraulic fluids clean and contaminant-free is easier with a specialty-engineered hydraulic filter from Bosch Rexroth Corp. The new 110 LE(N) "cyclone" filter series features a filter head that is designed to force incoming fluid to veer off at an angle alongside the filter instead of flowing directly through the filter element. The hydraulic fluid deflects off a protective sleeve and flows in a spiral pattern around the filter materials as it moves down toward the filter bowl....More

Product release: Self-contained filter cart

Model BFC 553 filter cart allows cleaning and transferring of petroleum-based fluids at a work site. It is designed to remove contamination as fluids are transferred from a drum and “polish” fluids in existing system. Its dc motor operates from an on-board rechargeable power supply, so it does not require an external power source. It can also be plugged into a 115-V power supply....More
