Air Driven Liquid Pumps Ideal for Intermittent Pressure Applications:

Milford, Conn., February 15, 2007 – Hydraulic pressures from 100 to 10,000 psi with only 60 psi air drive pressure can be achieved with positive displacement air driven liquid pumps with flows up to 6 GPM.

Interface Devices, Inc. (IDI), offers four different model air driven liquid pumps. The pumps incorporate robust design features such as aerospace PTFE based dynamic seals and aircraft quality aluminum components in a compact package.

E, H and P Series air driven pumps can be supplied with integrated hydraulic circuitry for cylinder actuation, pressure sensing and control or any other hydraulic function. The standard single acting TASQ™ pumps come with a NFPA DO3 valve pad. All IDI air driven pumps have a built-in air regulator for pressure control. Available options include self-contained oil reservoir, integrated shut-off valve and countless hydraulic circuit options built into the pump eliminating plumbing and external manifolds. The pumps require no lubrication or regulator. Clean and dry compressed air is all that is needed to operate.

E, H & P Series pumps are available in double acting and multi-ratio configurations for optimal efficiency. Multi-ratio pumps use a patented design to deliver high flow at low pressure and switch to high pressure mode on demand so minimum compressed air is used for each pressure cycle while maximizing actuation speed.

Air driven liquid pumps are well suited for intermittent flow and pressure applications such as clamping, crimping, roll tensioning, static pressure testing and power work holding. The pumps consume little or no energy upon achieving the desired hydraulic pressure. No heat is generated while maintaining pressure, eliminating the need for larger than required oil reservoirs or heat exchangers used with electric driven hydraulic units. In periodic pressure applications, air driven pumps are significantly cheaper to operate than traditional power units.
