Process pump gains fluororesin body
The PA series of compact high-capacity process pumps now includes a fluororesin body version for use in high technology environments.
SMC's PA series of compact, high capacity, process pumps, for the transfer and recovery of a wide variety of fluids, has now been enhanced with the introduction of a new fluororesin body version, which can be used in high technology environments These process pumps are designed for transferring liquid by suction, atomising liquid, transferring liquid by pressure and the stirring of liquid

Grease free stainless-steel fittings offer very high levels of corrosion resistance and can also be used with numerous piping materials.
Solenoid valves work well under pressure
Valves answer requests from process industry and PET machine builders for both two- and three-port pilot-operated solenoid valves with high pressure performance.
And these functions are used in many industries, such as coating/printing, cleaning, transfer and stirring of cleaning solvents, liquid transfer, filling and recovery of chemicals, machinery, metals automotive oils, organic solvents coating materials, and ceramics.
With the introduction of the new PA33/PAP33 series, with fluororesin body, the unit can now be utilised within food processing, for example where the transfer and replenishment of food products is required, as well as in the semiconductor industry where the transfer of acid and base resist liquids is undertaken.
(The PAP version has been introduced specifically for clean room environments, and is assembled in a clean room and shipped in a clean double package).

Positioning driver for AC servo motors
Positioning driver for use with AC servo motors is for point to point applications and can set parameters such as velocity, acceleration, deceleration and torque.
All units are rugged and can be specified as automatic (not requiring electric control) or air operated (with a reset function as standard - this is ideal when a pump is in an environment where the reset button cannot be operated manually).
In addition, the air operated type gives stable operation even with a minimal flow rate, low pressure, or liquid entraining gases.
The discharge rate is easily controlled, and repeated stoppage causes no problems to the pump.
(Maximum discharge, depending upon model chosen, can be up to 13 litre/min).
The units are compact and light - 124 x 152 x 19cm and around 2.1kg (PA33/PAP33).
SMC is confident that this new version will be as equally successful as the recently launched other versions.
Customer feedback has been very encouraging and one customer using the pump in a paint/solvent application has agreed to be quoted, saying: "Some of the most aggressive thinners and solvents were used during the tests, some of which were left in the pump for 48 hours.
We know that with any of the traditional pumps (within the finishing industry) that the 'thinners' test would be more than likely have required replacement of all seals in contact with the material".
He continues: "We took your pump apart, gave it a quick wipe around, and were extremely impressed with the ease of maintenance.
Its design, as simple as it is, is years ahead, includes design feature within the contact areas of the fluid chambers, which I have been wanting (no sharp edges, nice radii at critical points, easy to clean, good sealing features etc).
Another important feature is the fact that we can use the same pump to feed solvent, and/or water based materials.
Such a pump is difficult to find elsewhere".
