Open the catalog to page 1V100 BLACK INTELLIGENT PUMP Technical Datasheet BLACK EDITION MICRO PUMPS FROM XAVITECH CUSTOM CALIBRATION Xavitech’s Black edition is our pump model with the most functionality and flexibility. Our goal is for you to be able to use this micropump in your new system or as a dropin replacement in your existing system, in an easy and convenient way. The Intelligent Black edition pumps have built-in microcontrollers which makes it possible to create customized firmware for various purposes. Examples of customized firmware: • Set the flowrate to a specific value • Silent mode 20 000 hours,...
Open the catalog to page 2V100 BLACK INTELLIGENT PUMP General flow performance Free flow: 225 ml/min Flow can be calibrated to deliver a certain flow at a certain vacuum level. Ask us for more information. Maximum vacuum: -225 mbar Maximum pressure: 100 mbar IMPORTANT NOTES Pump Flow: Flow is one-directional, it cannot be reversed. Filters: To ensure lifetime, air filters should be used to prevent contaminations like dust to enter the pump. Connections: Incorrect lead connection can damage the pump. STANDARD MODELS (PART NUMBER) LIFE TIME (Hours) ANALOG FLOW CONTROL MAXIMUM PRESSURE/ MAXIMUM VACCUM (mbar) CONNECTION...
Open the catalog to page 3V100 BLACK INTELLIGENT PUMP Electronic interface Inside Pump 2.85 V DC Pull-up Molex 52610 or 52271 or similiar for flex cable Molex 530470510 for 3 or 5-wire connections Note: A VCC capacitor is required for 24-volt pumps * Serial interface applies on pump with flex or 5 wire connection Figure 2: Electronic interface INTERFACE DESCRIPTION Pump Cycle Maximum input voltage: Calibrated voltage + 0.5 V DC. The pump can be damaged otherwise. Minimum input voltage: 3.2 V DC. However, the pump performance is reduced if the voltage is set lower than calibrated value. Xavitech recommends to always...
Open the catalog to page 4V100 BLACK INTELLIGENT PUMP I/O X This is a general I/O connected to an A/D converter of the microcontroller inside the pump. The default functionality is frequency control: • 0 - 0.05 V DC: Pump stops • 0.06 - 2.7 V DC: Frequency control of the pump • 2.7 - 2.8 V DC: Maximum frequency of the pump • Max input voltage: 3.3 V DC (the pump can be damaged if exceeded) Note that the frequency adjustment can only lower the frequency from the factory default frequency. Normally a pump is calibrated to have its maximum frequency (maximum flow) set as default at factory. The use of I/O X can be...
Open the catalog to page 5V100 BLACK INTELLIGENT PUMP Serial interface I2C Interface To use the I2C interface, pull-up resistors needs to be added to the SDA and SCL lines (see Figure 2). Suitable values depend on the bus capacitance. Some master devices have built-in pull-up resistors. A Raspberry Pi for example has 1.8 kOhm resistors installed. Recommended I2C speed grade is standard mode: 100 kbit/s, but up to 400 kbit/s (full speed) is supported. Actual maximum speed depends on bus capacitance, pull-up resistors used and interference from other circuitry etc. Logic levels are 2.8 V (max 3.3 V). The standard...
