How can we improve?

392 Products

Fluid Handling

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

Test Pumps

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

Drum Pumps

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

Manifolds

Distribute air or fluid to multiple places from a single source; also called headers

Hose Fittings

Create threaded, barbed, quick-disconnect, and other types of connections between lengths of hose

Hose

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

Flow-Adjustment Valve Manifolds

Flow-Adjustment Valve Manifolds

Control flow to multiple points from one source

Flow-Adjustment Valves

Flow-Adjustment Valves

Gradually open and close to control the volume of air and liquids through a line

Air Evacuators

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

Pressure Gauges

Pressure Gauges

Measure pressure in pumps, filters, regulators, and process lines

Material Handling

Jack Pumps

Pump hydraulic oil into jack rams to create hydraulic jacks

Jacks

Lift, hold, push, and position heavy objects

Jack Rams

Attach to jack pumps to lift, push, or pry apart objects with hydraulic power

Jack Mounts

Thread onto jack rams to secure them to a surface

Power Transmission

Hydraulic Power Units

Hydraulic Power Units

Create and supply hydraulic pressure to keep hydraulic systems running

Pump-to-Motor Mount Adapters

Pump-to-Motor Mount Adapters

Mount motors to hydraulic pumps to reduce noise and guard shaft and coupling connections

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
