GAST Manufacturing introduces GAST range of vacuum pumps and compressors

January 20, 2017 - GAST Manufacturing, a designer and manufacturer of precision air products and member of IDEX Corporation’s Health & Science division, introduced a range of vacuum pumps and compressors. The three pump and compressor ranges include sixteen oil-free and oil-lubricated rotary vane models and, in a first for the organization, four claw pump models.

GAST Claw Pumps

GAST’s four claw pump models – PA.155, PA.315, VA.155 and VA.315 – use contactless rotors that are synchronized by gears without any lubrication in the pumping chamber. This frictionless operation avoids any residue (generated by rubbing during rotation) from contaminating the air supply.
With nominal capacities from 186 to 360m3/h at 60Hz, vacuum capability to 25.5”HgV and pressures up to 17psi, the GAST claw pump range is ideal for numerous vacuum, compression, aeration, extraction and drying applications in sectors including printing, environmental, medical, bulk material handling, CNC machining and vacuum hold-down.

GAST Oil-Free Rotary Vane Pumps

Adding to a portfolio of rotary vane pumps, two oil-free models – SB.16 and SB.40 – being introduced feature an industrial Monobloc design with the rotor assembled directly on the motor shaft. Additionally, a rear centrifugal fan ensures optimal cooling of the pump and each model is equipped with protective filters at the inlet and silencers at the outlet. Both models are also suitable for use as compressors.

A third model, the SC.100, has the rotor installed on the shaft and fixed by two bearings, with the motor being connected by a flexible coupling. The fan is installed between the pump housing and motor to ensure optimal cooling.

GAST’s oil-free rotary vane models offer nominal capacities from 19 to 150m3/h at 60Hz. All models provide vacuum in excess of 26”HgV and are ideal for applications including printing, conveying, wood/plastic presses, automated packaging and pick and place operations.

GAST Oil-Lubricated Rotary Vane Pumps

Ideal for applications such as laboratory conditioning/refrigeration appliances, mass spectrometry, packaging, medical equipment, thermoforming machines and glass and marble machining, GAST’s ten-model range of oil-lubricated rotary vane pumps – including the LB.8, LC.12, LC20, LC.25, LC40, LC60, LC106, LC151, LC.205 and LC.305 – are ideal where the intake flow may require higher flow and deeper vacuum.

Additionally, and for applications where intake vapour is considerable, a WR version also features an integral system that separates oil and water condensate, which is then expelled when the pump is stopped.

All six oil-lubricated models offer nominal capacities from 9 to 365m3/h at 60Hz and total final pressures between 1.5 and 0.08 Torr.
