100% Stainless Steel
Without Oil Reservoir
Without Adjustable Overload Relief Valve
Without Manual Pressure Release Valve

These pumps, either base or flange mounted style, have only check valves. They have no reservoirs, overload relief, or release valves, and are used on equipment that has its own reservoir and control valves. These pumps provide a low cost efficient means for manually developing or increasing pressure in a hydraulic system. In emergencies they furnish reliable hydraulic power to operate presses, valves, doors, safety locks and other devices.

Features:

• Available in hand or foot operated versions
• A flange mount version is available
• Provides pressure up to 10,000 PSI
• Supplied with a 24" operating handle or foot lever
• Often used as a stand-by pump for emergencies
