Hydraulic Pumps
been the "standard" hydraulic fluid used in power circuits. This situation remains today, but is changing as safety considerations and government compliance agencies force greater acceptance of fire-resistant hydraulic fluids. Most pumps used today were designed for petroleum fluids -- oil

Hydraulic Hose
Hose is widely used in applications where lines must flex and bend. System pressure, pressure pulses, fluid velocity, temperature, fluid, and environmental conditions form important factors in the use of hydraulic hose. Hoses are impulse tested from 100 to 133% of rated pressure, to allow

Hydraulic fluids change with the times
The right chemistry minimizes operating problems and saves money. Hydraulic and Industrial Gear Additives Using the wrong hydraulic fluid can have severe and costly consequences, such as catastrophic pump failure. Hydraulic fluids are the workhorses of hydraulic systems. They transmit power

Body Armor for Hydraulic Hose
A leaky hose can shoot fluid at bulletlike velocities. Here's how to better-protect workers. Protective covers such as textile/nylon sleeving and flat plastic or metal-spring guards have long been used to prevent cuts and abrasive wear of hydraulic hose. But the covers typically offer little

Pressing need for hydraulic servos
Makers of stamping presses and die casters increasingly use servocontrols to boost throughput while minimizing equipment wear and tear. The trend is clear: More and more metalworking presses are going with servocontrol. "At trade shows, you increasingly see only hydraulic servos or presses running

Hydraulic "Batteries" Save Fuel
Accumulator-based energy recovery systems improve mobile-equipment efficiency. Hydropneumatic accumulators are widely used in industrial and mobile hydraulic systems because they provide auxiliary power during peak periods. This lets designers select smaller pumps, motors, and reservoirs
-
Hydraulic and Pneumatic Filters
The typical hydraulic system is cleaned by a single filter in the circuit. Often this filter is located on the inlet line in front of the pump, to protect the pump and downstream components; so used, it is occasionally called a "suction filter" or "suction strainer." Many pump manufacturers object

Body Armor for Hydraulic Hose
covers such as textile/nylon sleeving and flat plastic or metal-spring guards have long been used to prevent cuts and abrasive wear of hydraulic hose. But the covers typically offer little or no protection to workers from bursts and pinhole leaks. With the demand for more-compact,higher-pressure systems
