SMC Pneumatics has released the PA3310 and the clean room PAP33135 compact process pumps on the Australian market.

Among their attractions, the new pumps use PFA for all wetted parts, ensuring high corrosion resistance and long life.

One of the greatest factors differentiating the new pumps from others on the market, however, is their design, which brings high performance and output to a tightly compact unit.

The pumps are 120mm deep, 140mm long, 110mm wide and weigh in at just 2.1kg.

Capable of working with ambient and fluid temperatures of 0 to 100ºC, the pumps have a proof pressure of 0.75MPa and a pilot air pressure of 0.2 to 0.5MPa.

The new pumps are suitable for most environments, particularly those where access may be difficult. They feature air pilot actuation as standard, enabling resetting to be carried out by releasing the air pressure after supplying it to the reset port.

Air pilot actuation also facilitates constant cycling, repetitive stopping during operation, and stability in conditions of minimal flow, low pressure or when gases are entrapped.

For clean applications, the new PAP series pumps are assembled and double-packaged in a clean room environment. To ensure the integrity of the pump is retained when in use, its side bodies and ports have been moulded to greatly reduce the chance of dust generation.

Both the PA and PAP series pumps are suitable for a range of applications using fluids such as IPA, de-ionised water, methyl ethyl ketone and hypochlorous acid soda, and have a discharge rate of up to 13L/min depending on whether air pilot actuation or auto-operation is selected.
