Interface Devices is a world leader in manufacturing air-driven liquid pumps for hydraulic applications with intermittent flow and pressure demands. These pumps are ideal for situations where a constant pressure is required, especially over longer periods of time. If no leaky valves are present, the intensifier pump will hold pressure for days on end without consuming any energy or generating heat. All moving parts are non-ferrous and there is no metal-to-metal contact, making the pumps suitable for use in explosion-proof and Hazmat environments. In many applications, IDI Air-driven liquid pumps can be an economical alternative for traditional electric Hydraulic Power Units. They are nearly 100% efficient, so no energy is wasted.
