Pumps & Compressors

Piston oil-free Air Compressor

There are typically three types of hydraulic pump constructions found in mobile hydraulic applications. These include gear, piston and vane; however, there are also clutch pumps, dump pumps and pumps for refuse vehicles such as dry valve pumps

For truck-mounted hydraulic systems, the most common design in use is the gear pump. This design is characterized as having fewer moving parts, being easy to service, more tolerant of contamination than other designs and relatively inexpensive.

This complexity falls to the equipment designer and service technician to understand in order to ensure the piston pump is working correctly with its additional moving parts, stricter filtration requirements and closer tolerances.

In general, they power a number of tools used for construction work or building, such as jackhammer, sanders, and grinders. Air compressors pump high-pressure air to fill gas cylinders, to supply divers, to help in powering pneumatic HVAC control systems, and to power pneumatic tools.

Hyperbaric patients often need dozens of treatments, each requiring a separate visit to a clinic or hospital with a treatment time of 90 minutes.
