Greener pump ranges for greater flow and deeper vacuum

13 April, 2017

Gast – the designer and manufacturer of precision air products and member of the IDEX Corporation – is introducing a new range of vacuum pumps and compressors to its extensive portfolio. These new products are simple in operation, robust and an effective source of compressed air. The three pump and compressor ranges include 16 oil-free and oil-lubricated rotary vane models and, in a first for the organisation, four claw pump models.


Gast Group’s Andrew Lidington, commented: “Gast is already renowned as a world-class manufacturer of vacuum pumps and compressors and these additions to our portfolio will provide customers with products that, compared to our traditional offering, can deliver even greater flow and deeper vacuum. The addition of claw pumps also perfectly complements our portfolio and opens up new industries and sectors that we haven’t been able to participate in previously.

“Using simulation software and the latest manufacturing techniques, we believe that the performance of our new rotary vane and claw pump models are class-leading. The range is also more environmentally-friendly than ever and, thanks to extended maintenance schedules, total cost of ownership is also significantly improved.”

Gast claw pumps

Claw pumps are an often-overlooked technology due to a slightly higher initial cost. However, compared to oil-free rotary vane, claw pumps use significantly less horsepower to provide similar vacuum capability. They also provide 100% duty cycle and, with no carbon vanes and significantly less gear lubricant to replace, are quicker, easier and cheaper to maintain.

With only moderate energy consumption and very high efficiency, Gast’s four new claw pump models – PA.155, PA.315, VA.155 and VA.315 – use contactless rotors that are synchronised 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; and means lower maintenance and operating costs, longer lasting performance and improved total cost of ownership.

With nominal capacities from 155 to 250m3/h at 50Hz, vacuum capability to 150mbar(abs) and pressures up to 2bar, 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 an already impressive portfolio of rotary vane pumps, two new oil-free models – SB.16 and SB.40 – being introduced feature an industrial Monobloc design with the rotor assembled directly on the motor shaft. This direct-drive design means fewer moving parts, making these new dry vacuum pumps extremely compact, reliable and easy to maintain. 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.
