Power Transmission

Hydraulic Power Units

Hydraulic Power Units

Create and supply hydraulic pressure to keep hydraulic systems running

Hydraulic Motors

Hydraulic Motors

Power equipment where electric motors aren't safe and air-powered motors aren't strong enough

Hydraulic Cylinders

Hydraulic Cylinders

Push and pull heavy loads to operate forklifts, compactors, and other machinery

Air to Hydraulic Power Units

Air to Hydraulic Power Units

Power a hydraulic cylinder with air to avoid the setup, cost, and mess of hydraulic fluid

Hydraulic Actuators

Hydraulic Actuators

Turn heavy loads to do everything from opening tank doors to pivoting conveyors

Hydraulic Check Valves

Hydraulic Check Valves

Open to allow hydraulic fluid flow in one direction and close when flow stops or reverses

Hydraulic On-Off Valves

Hydraulic On-Off Valves

Control the flow in high-pressure hydraulic systems

Fluid Handling

Double Diaphragm Pumps

Double Diaphragm Pumps

Transfer liquids, chemicals, and slurries using compressed air

Test Pumps

Force air or liquid through your system to look for leaks; often called hydrostatic test pumps

Gear Pumps

Create fixed liquid flow rates to cool engines, power hydraulic equipment, and extract liquids

Rotary Vane Pumps

Rotary Vane Pumps

Evenly move water or hydraulic fluids at high pressures in low-flow applications

Drum Pumps

Draw liquids out of drums, pails, and other small containers

Pipe and Fittings

Pipe and Fittings

Generally thicker and more rigid than tubing for distributing liquids and gases

Hose

Flexible and stronger than tubing; often used to convey liquids and gases under pressure

Tubing

Typically more flexible than pipe for carrying liquids and gases in short runs around equipment

Hose Crimpers

Crimp ferrules onto hose to secure fittings

Pressure-Regulating Valves

Pressure-Regulating Valves

Reduce inlet pressure to a lower outlet pressure to protect sensitive equipment

Pressure-Relief Valves

Pressure-Relief Valves

Protect equipment by opening at a set pressure and closing when the pressure drops; for repeated use

Hydraulic Accumulators

Hydraulic Accumulators

Maintain pump flow, stabilize pressure, and absorb shock during pump failure

Air Evacuators

Flush air bubbles from hydraulic fluid without using compressed air or electricity

Hydraulic Fluid Filters

Hydraulic Fluid Filters

Move where needed to add hydraulic fluid to systems and strain out contaminants

Directional Control Valves

Directional Control Valves

Manage the flow of fluids to move equipment in air- and hydraulic-powered systems

Flow-Regulating Valves

Flow-Regulating Valves

Maintain the set flow rate of fluid through your system

Containers, Storage, and Furniture

Hydraulic Tanks

Hydraulic Tanks

House fluids for hydraulic power units and circulating-oil systems
