Part number 03212135 (often appearing as 03212135S01) refers to a Becker VX 4.25 oil-free rotary vane vacuum pump used in ASM SIPLACE pick-and-place machines. It provides the negative pressure (suction) required for the nozzles on the placement heads.
Key Specifications
This pump operates dry (100% oil-free) and utilizes self-lubricating graphite composite vanes, eliminating the need for oil changes. At 50Hz, it offers a pumping speed of 25 m³/h, an ultimate vacuum of 100 mbar, and a power rating of 0.75 kW; it produces approximately 62 dB(A) of noise and weighs about 26 kg (including the motor). At 60Hz, the pumping speed increases to 30 m³/h, with a power rating of 0.9 kW.
Role in Pick-and-Place Machines
This vacuum pump serves as the negative-pressure source for the machine’s pneumatic system and is specifically designed to support the vacuum-driven operation of CP20 series placement heads. Compared to vacuum generators powered by compressed air, an independent vacuum pump provides more stable and consistent suction, which is advantageous for the high-speed pick-and-place of miniature components. The graphite vanes are consumable parts (reference part number 03077679); as they wear down, the vacuum level will decrease, leading to an increase in component rejection rates (pick-and-place errors).
